Cross-sensitivity Lowered by H2S Sensors

Jan 29 2009

Membrapor (Switzerland) has successively lowered the Cross-sensitivity of its H2S-sensors. The type H2S/C-50 for measurements in the range of 0 – 50 ppm H2S exhibits an interference to CO of only 0.4 percent, which is an unbeatable figure. The product line has now been developed for concentrations of up to 5,000 ppm of Hydrogen sulphide.
Also with the Hydrogen sensor H2/CA-1000 the cross-sensitivity to CO could have been lowered further and is now as low as just 1 percent.
A shortening of the response time has been achieved with the SO2-sensors. They show now a t90 less than 20 seconds and an extremely stable signal over extended time. A new replacement of the 3-Series, the SO2/SF-100-S (Range 0-100 ppm, overload at 500 ppm) has been launched. This Slim-sized sensor represents our product line for flue gas analysers, which exhibit a quality you can rely on under the harsh conditions of emission gas monitoring.
The housing of the Compact-size has been redesigned to offer the robustness and durability required for industrial applications. It allows for a Compact sensor to be easily mounted on an exhaust pipe ensuring full functionality.
The favoured HCl-sensor in the Compact-housing is now available with a measurement range of 0 to 200 ppm. For the same concentration range the new ozone sensor O3/C-200 has been introduced. In the Miniaturehousing, a two-electrode variation of the ammonia sensor has also been released.
Due to continuous efforts in development at the research centre in Zürich a product range of sensors for 16 gases has been successfully established. Membrapor has further extended its market position as independent sensor producer for toxic gases. All of the more than a hundred different sensors are produced in Switzerland and supplied to the world`s gas detector manufacturers for flue gas analysers, personal safety monitors, fixed-point detection systems, portable gas detectors, breath checkers and air quality monitors.
