SPM FLEX Optical Gas Analyser

The SPM FLEX is an optical gas analyser combining the colour change of a chemically impregnated paper strip with a powerful optic analysis system. It is particularly suitable for the detection of mineral acids (HNO3, H2SO4), hydrides (H2Se, H2S, SiH4), amines (DMA, TD-MAT), and diisocyanates (TDI, MDI, HDI) at low concentrations (in ppb).

  • Detection of hydrides, mineral acids, oxidants, amines, diisocyanates, phosgene, hydrazines, hydrogen peroxide, etc.
  • Patented Chemcassette┬« technology: fast, highly accurate analysis method insensitive to interferences
  • Integrated gas sampling pump (up to 30 meters for some gases)
  • Digital display of target gas concentration in ppb (parts per billion)
  • Minimal maintenance with no need for calibration
Additional information

The SPM FLEX optical gas analyser has a sampling pump for remote gas sampling. The gases go onto a chemically impregnated paper strip. Upon reaction with the target gas, the paper strip will change colour for analysis by a highly optical system.

CHEMCASSETTE measurement strips are interchangeable, pre-calibrated, and Plug-n-Play, which greatly facilitates maintenance and associated costs as there is no need to perform a calibration after replacement. It is particularly relevant for periodic verification of the gas sensor as there are no calibration gases with such low calibration concentrations.

The SPM FLEX optical gas analyser contains three alarm relays, a 4-20 mA analog output, Modbus and TCP digital outputs for instrument connectivity, a USB port for sharing configuration, and updating software and downloading data.
