Details: Professional series O2 detector with pump by FORENSICS. High precision for accurate measurements, robust fieldwork, research, inspections, occupational safety, industrial, and environmental applications. The pump allows for point probe or continuous sampling. Comes factory-calibrated. The detection range of O2 is 0 - 30% within 30 seconds with an error less than +/- 5% full scale. Advanced features include temperature detection, alarm recording, alarm setting, backlight high-resolution LCD, and calibration.

The handheld pump has a gas input from a stainless probe (8.6-inch length). Gas output is a male 3.2 mm tube connector that connects to standard aquarium tubing with a diameter of 3/16 in. The pump has a rechargeable DC 3.0V Li-battery 1500 mAh, charged via a USB connector. Pump LCD shows temperature detection, time, and date with high-resolution backlight. The power load indicator of pump resistance is also clearly shown so the user has insight into the pump load. Ideal for point sampling of toxic gas or remote sampling (can operate up to 50 feet).

Included: Gas detector, English manual, computer USB charging cable, calibration cover, and USA NIST calibration certificate. The pump unit comes with the pump, stainless probe, 3 ft silicone tubing, USB charging cable, and English manual.
