Sensidyne is a manufacturer and distributor of gas detection and air sampling instrumentation and a major supplier of gas detection tubes.
In 1995, the Gilian Instrument Company was acquired to expand the existing line of personal air sampling pumps. The trademark of Gilian® continues to flourish under the Sensidyne banner and continues to be the most recognized brand globally for high performance vapor and particulate monitoring equipment.
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.
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.
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.
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.
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.
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.
