Carbon Dioxide Monitor Devices
Our devices monitor carbon dioxide and carbon monoxide concentration, temperature and relative humidity. The Air quality parameters on many models are displayed simultaneously on the LCD display. Built in data logging kits can store multiple data points.
Applications
These Carbon Dioxide Monitor devices are the ideal tools for investigating Indoor Air quality and performing thermal comfort studies. They simultaneously measure and data log multiple parameters. They will accurately measures carbon dioxide (CO2), temperature, humidity, and calculates dew point and % outside Air.
Sources of Carbon Monoxide
Unvented kerosene and gas space heaters; leaking chimneys and furnaces; back-drafting from furnaces, gas water heaters, wood stoves, and fireplaces; gas stoves; generators and other gasoline powered equipment; automobile exhaust from attached garages; and tobacco smoke. Incomplete oxidation during combustion in gas ranges and unvented gas or kerosene heaters may cause high concentrations of CO in indoor Air. Worn or poorly adjusted and maintained combustion devices (e.g., boilers, furnaces) can be significant sources, or if the flue is improperly sized, blocked, disconnected, or is leaking. Auto, truck, or bus exhaust from attached garages, nearby roads, or parking areas can also be a source.
Carbon Monoxide Monitor over view
A Carbon Monoxide Monitor or CO detector is a device that detects the presence of the carbon monoxide (CO) gas in order to prevent carbon monoxide poisoning. CO is a colorless and odorless compound produced by incomplete combustion. It is often referred to as the "silent killer" because it is virtually undetectable without using Carbon Monoxide Monitor technology. Elevated levels of CO can be dangerous to humans depending on the amount present and length of exposure. Smaller concentrations can be harmful over longer periods of time while increasing concentrations require diminishing exposure times to be harmful. A Carbon Monoxide Monitor is designed to measure CO levels over time. While a Carbon Monoxide Monitor does not serve as a smoke detector and vice versa, dual smoke/CO detectors are also sold. Smoke detectors detect the smoke generated by flaming or smoldering fires, whereas a Carbon Monoxide Monitor warns people about dangerous CO buildup caused, for example, by a malfunctioning fuel-burning device. In the home, some common sources of CO include open flames, space heaters, water heaters, blocked chimneys or running a car inside a garage.
About VOC and VOC Monitor Device Instruments
VOCs may be natural or synthetic. Like organic chemicals in general, there are many different compounds which may be classified as VOCs. The compounds the nose detects as smells are generally VOCs. Modern industrial chemicals such as fuels, solvents, coatings, feedstocks, and refrigerants are usually VOCs.
As organic chemicals, VOC may have health consequences, but this is depending on the specific chemicals that are part of the umbrella definition "VOC". For indoor Air purposes, there are long lists of limit values published. Because they tend toward the gaseous state, management of toxic VOCs is more difficult than with non-volatile compounds. Human exposure to VOCs can be through contact with the solid, liquid, or gaseous forms, inhalation of the gaseous form, or ingestion of the liquid form or solutions containing the VOC.
Background to dust monitoring Instruments for Indoor Air Quality
dust is generally understood to be an aerosol of solid particles, mechanically produced, with individual particle diameters of 0.1µm upwards and can be a problem in almost any industry, from bakeries to building sites. Nuisance dust is generated by a wide range of activities, including traffic; construction/demolition; mineral workings and general industry.
With increasing awareness of the problems caused by dust generated from such works, many local authorities are now including dust monitoring as a planning requirement. Often there is a requirement to undertake a baseline survey, particularly as part of an EIA, in order to formulate acceptable thresholds.
Vibration Noise Monitoring Instruments
Vibration white finger (also known as hand-arm vibration syndrome and dead finger) is a secondary form of Raynaud's disease, an industrial injury triggered by continuous use of vibrating hand-held machinery. Use of the term Vibration White Finger has generally been superseded by Hand-Arm Vibration Syndrome or HAVS. The symptoms of VWF are the vascular component of HAVS.
HAVS is a widespread recognized industrial disease affecting tens of thousands of workers. It is a disorder which affects the blood vessels, nerves, muscles, and joints, of the hand wrist and arm. Its best known effect is vibration-induced white finger (VWF), a name coined by the Industrial Injury Advisory Council in 1970. Injury can occur at frequencies between 5 and 2000 Hz but the greatest risk is between 5 and 150 Hz.
The Control of Vibration at Work Regulations 2005 is the legislation that governs exposure to vibration and assists with preventing HAVS occurring.
Good practice in industrial health and safety management requires that worker vibration exposure is assessed in terms of acceleration amplitude and duration. Using a tool that vibrates slightly for a long time can be as damaging as using a heavily vibrating tool for a short time. The duration of use of the tool is measured as trigger time, the period when the worker actually has their finger on the trigger to make the tool run, and is typically quoted in hours per day. Vibration amplitude is quoted in metres per second squared, and is measured by an accelerometer on the tool or given by the manufacturer. Amplitudes can vary significantly with tool design, condition and style of use, even for the same type of tool.
The UK Health and Safety Executive gives the example of a hammer drill which can vary from 6 m/s² to 25 m/s². HSE publishes a list of typically observed vibration levels for various tools, and graphs of how long each day a worker can be exposed to particular vibration levels. This makes managing the risk relatively straightforward. Tools are given an Exposure Action Value (EAV, the time which a tool can be used before action needs to be taken to reduce vibration exposure) and an Exposure Limit Value (ELV, the time after which a tool may not be used).
The National Institute for Occupational Safety and Health published a similar database where values for sound power and vibrations for commonly found tools from large commercial vendors in the United States were surveyed. Further testing is underway for more and newer tools.
The effect of legislation on worker vibration limits is intended to drive employers to provide better-designed, better-maintained tools, and to train workers appropriately. It also drives tool designers to innovate to reduce vibration. One example is the suspension mechanism designed into chainsaws.
ATEX approved Intrinsically Safe Noise dosemeter
A noise dosimeter (American) or noise dosemeter (British) is a specialised sound level meter intended specifically to measure the noise exposure of a person integrated over a period of time; usually to comply with Health and Safety regulations such as the EU Directive 2003/10/EC, or the equivalent American OSHA rules.
The next technology breakthrough came when in the 1990s the United Kingdom Department of Trade and Industry awarded a SMART grant to design an ultra-miniature dosimeter. It was to be so small and light that it would not affect the worker and as well was to have no microphone cable. The resulting device, the first true dosebadge - was a twin channel device able to meet all the requirements of the European Directive and also the market need for data storage. An important design criteria was that the device had to have no internal display nor any controls, so workers would not be tempted to try to 'modify' or affect the readings; instead the acquired data was transmitted and the device was controlled by an infra-red link. Normally, the acquired exposure data from several badges is transferred to a reader unit where it can be read and stored. As well, most manufacturers offer software to transfer the reader's data to a computer where it can be archived and as well put into a database to allow full and complete reports to be generated.
Today, such devices are available from several manufacturers - at least one with a full Intrinsic Safety certificate for use in hazardous atmospheres. Some sophisticated ones have extra channels to store data on the state of the battery, any 'out of range' signals and some units are able to be used on the USA OSHA as well as EU equal energy rules, although a different physical badge is usually needed. Others have a "Time History" store, where the exposure minute by minute is stored for the full working shift, allowing Health and Safety Officers to pinpoint the exact time of any high energy noise and assist in determining the cause.
These new devices are split into two groups. Those that have no display on the body-worn acquisition unit, and those that include such a display. Latest generation Noise dosemeter can be set up from the simple front panel or from a PC via QuestSuite Pro software Displays Leq, Lmax, Lpk, runtime as well as dose and sound measurement
