Even from a distance, the sensor reliably captures oxygen and hydrogen sulfide gas. The gas concentration is clearly displayed at hand.
■ Separation type for display and sensor units In underground locations such as manholes, gas can be measured by inserting the sensor unit from above ground. This separation type takes advantage of pre-safety checks and ensures the safety of workers, making it useful in various settings. ■ Large LCD display that is easy to read. User-friendly one-touch operation. Gas concentration is displayed in large, easy-to-read three-digit digital numbers. Operation is simple with one-touch functionality. ■ Simultaneous measurement of two gases (oxygen and hydrogen sulfide). Both oxygen and hydrogen sulfide gases can be measured simultaneously. The concentration display for each can be easily switched by pressing a button. ■ Equipped with alarm function. An alarm sounds when the oxygen concentration falls below 19.5% or when the hydrogen sulfide concentration exceeds 10ppm, and the LCD also flashes to alert. ■ The sensor unit has a drip-proof structure. The display unit is also made drip-proof with a leather case. ■ Automatic calibration at 21.0vol% and adjustment function for 0ppm.
