WM-SEM227 - Louver versatile sensor

Maritex would like to inform you about the extension of the meteo sensor offer with the Louver versatile sensor WM-SEM227. WM-SEM227 has the ability to integrate several meteorological sensors in one housing with a radiation shield:

  • Air: temperature, humidity, pressure;
  • Illuminance;
  • Noise, CO2, PM2.5 / PM10 / PM1.0, O2, H2S etc. (for details refer to the table below);

  • One-piece radiation box structure with the possibility of integrating several sensors;
  • Integration of TVOC, CH2O, O3, oxygen, H2S, methane, carbon monoxide, nitrogen dioxide (NO2), sulfur dioxide (SO2), hydrogen (H2), ammonia and many other measuring sensors;
  • The sensor is characterized by a wide measuring range and high water resistance;
  • Electrochemical and catalytic sensors are used in the gas concentration measurement element, which are characterized by excellent sensitivity and repeatability;
