Details: Professional series H2S monitor with the pump by FORENSICS. High precision for accurate measurements in fieldwork, inspections, occupational safety, industrial, and environmental applications. The pump allows for a robust point probe or continuous sampling. Comes factory-calibrated. The detection range of H2S is 0 - 100 ppm within 30 seconds, with an error of less than +/- 5% full scale. Advanced features include temperature detection, alarm recording, alarm setting, backlight, high-resolution LCD, and calibration.
The handheld pump gas input is taken from a stainless probe (8.6-inch length). Gas output is a male 3.2 mm tube that connects to standard 3/16" aquarium tubing. The pump has a rechargeable DC 3.0V Li-battery (1500 mAh) charged via a USB cable. The backlight LCD shows temperature detection, time, and date in high resolution. The power and pump resistance are also clearly indicated so the user has insight into the pump load. Ideal for point sampling toxic gas remotely (can operate up to 50 feet). We also offer a built-in pump version with our FD-600-H2S H2S Monitor Analyzer.
Included: H2S Monitor, user manual, computer USB charging cable, calibration cover, and certified calibration certificate. The pump unit comes with the pump, stainless probe, 3 ft silicone tubing, USB charging cable, and user manual.
