The FORENSICS DETECTORS FD-4S multi-gas detector measures oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S) and flammable gases (LEL). It uses electrochemical sensors for CO, H2S and O2, and a catalytic sensor for LEL. The colour LCD and graphical displays make readings easier to view. Sampling is by diffusion, without a pump, and the device is supplied calibrated.
Adjustable alarms alert you with LEDs, a buzzer and vibration. The detector is resistant to shock, water, dust and explosions, and comes with a signed and dated calibration certificate.
