The FORENSICS DETECTORS FD-90A-O2-PUMP oxygen detector with external pump measures O2 concentrations from 0 to 30%, with a resolution of 0.1%. It uses a NANO-GAS electrochemical sensor and supports spot measurements or continuous sampling. The pump has a flow rate of 0.5 LPM and enables remote sampling from up to 50 ft away.
Adjustable alarms are audible, visual and vibration-based. The detector also features temperature detection, alarm logging and adjustment, a backlight and calibration mode. It is shock-resistant, water- and dust-resistant, and ATEX-certified (Ex ia IIC T4 Ga). It is not intended for continuous indoor oxygen monitoring.
