Electrochemical sensors. Comes FACTORY-CALIBRATED. 🌇 DETECT: Sensor ≤ ± 5% F.S. and response time: < 30 sec. Zero and span calibration options. Comes factory-calibrated. Perfect for point, continuous, air, gas, and vapor sampling. 🎆 ALARMS: Adjustable audio, visual, and vibration alarms alert when preset levels are reached. 💪 STRONG: Designed for industrial fieldwork. Shockproof, water-resistant dust-proof, and explosion-proof with belt clip. Rechargeable Li-ion battery 1500 mAh via micro-USB cable, comes with all accessories. 🕵️ TRUSTWORTHY: 1-year limited warranty. Arrives with a signed and dated calibration certificate. 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 a 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. Not to be used as a continuous indoor monitor. Use FD-60-O2 for indoor continuous oxygen monitoring. Comes factory-calibrated. 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. The pump LCD shows temperature detection, time, and date with a 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: Oxygen gas detector, 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.
