The sensor mounting height depends the type of application and on the density of the gas relative to air. Heavier than air gases should typically be detected 6 inches from the floor, lighter than air gas sensors should typically be placed on or near the ceiling, and gases which have a density close to that of air should have sensors installed in the "breathing zone" 4 6 feet from the floor.
GasEye Cross Duct SO2 insitu SULFUR DIOXIDE ANALYZER. GasEye SO2 is a high performance insitu sulfur dioxide analyzer. Suitable for safety applications and process control. 24/7 continuous operation. No sample preparation. No zero drift.
The GasAlert Extreme SO2 Monitor offers reliable protection for personnel at risk for sulfur dioxide exposure. This sulfur dioxide meter has a range of 0100 ppm, well above the OSHA limit of 5 ppm TWA. The stout, rubberized case is waterresistant and requires little maintenance. The immediate readout on the LCD screen, along with its multiple alarms and alligator clip, makes it a convenient ...

DualSense technology uses two sensors of the same type to determine the concentration of a target gas in the atmosphere and reduce the risk of instrument failure while improving gas reading accuracy. LENS is the first wireless gas detection solution that allows personal monitors and area monitors to communicate gas readings and alarms with one another.
10/12/2012· SO2 sensors have a cross sensitivity of approximately 150% to acetylene gas meaning if there are 45ppm acetylene gas in the air then your SO2 …
The SGTP portable sulphur dioxide monitor has a leading 24 month warranty from despatch. In addition to this, the SO2 sensors have an industry leading 35 year lifetime. This ensures that when you buy a SGTP portable sulphur dioxide detector from IGD, you are guaranteed to have a monitor that will withstand even the harshest environments.

Calibration gas is a reference gas or a mixture of gases which are usually compressed. The composure of calibration gas exists of one initial gas and is enhanced by one or more component (s). Calibration gas is used to calibrate gas analysers or gas detectors. All SEMA calibration gases are traceable according to national (Dutch) as well as ...
C2H2 gas detector (Acetylene) As acetylene is colorless and odorless when pure, only a C2H2 gas detector can accurately measure concentrations of this gas. Two acetylene detection methods are available: either in toxicity with a ppm measurement (PortaSens), or in explosivity with LEL percentage measurement (combustible gas detector).
The sensor data listed is based on the test data under normal lab test conditions (20°C to 25°C, 0% RH to 60% RH, normal atmosphere pressure); observed performance may vary based on the actual monitoring system and the sampling conditions employed. NOTE: The SO2 sensor should not be used with O3 or HF sensor in the same Midas®M unit.
For highly sensitive and accurate acetylene (C2H2) detection, a nearinfrared (NIR) offaxis integratedcavity output spectroscopy (OAICOS) sensor system based on an ultracompact cagebased absorption cell was proposed. The absorption cell with dimensions of 10 cm × 8 cm × 6 cm realized a densepattern and an easilyaligned stable optical system.
DrägerSensor XXS. Dräger has developed miniature electrochemical sensors specially for the Dräger Pac ® , Xam ® 1/2/5 and Xam ® 8000 generation. The sensors detect many different gases and vapours. They are also very reliable and stable over the longterm, thereby reducing your operating costs. Request a Quote.
Conversely, some gases are extremely poisonous to the sensor and can ruin its accuracy in a matter of minutes. Gases that absorb onto the catalyst (, acetylene for CO sensors) or gases that react and inhibit the catalyst (, NO2 for H2S sensors) will prevent proper
One example is to use a CO or an SO2 sensor to detect Phosphine fumigation gas. Both the CO and SO2 sensors have high crosssensitivity to PH3 gas and are suitable for high ppm level PH3 monitoring. Problematic Cross Sensitivity CO sensors are highly responsive to H2, Acetylene, Ethanol and Alcohol.

Cross references. Electrochemical sensors are manufactured as specific sensors for one gas, for all that there exist some cross sensitivities to other gases. Generally these cross references are not a problem in gas detection in the area of safety, but they can be a complication in the process detection they can cause false alarms.
