The FORENSICS DETECTORS FD-4S-PUMP 4-gas detector with pump measures oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S) and combustible gases (LEL). The pump supports sampling with a probe or continuous sampling, while the detector features a 32-bit microprocessor, a color LCD and graph display. It comes with a signed and dated calibration certificate.
The CO, H2S and O2 sensors are electrochemical, while the LEL sensor is catalytic. The unit features LED, audible and vibration alarms and is intended for testing the air before entering or working in confined spaces.
