Handheld Pump Oxygen Meter, Oxygen level detector for Concentration and Air Quality Detection

Measuring Range :


The Handheld Pump Oxygen Detector is an advanced O2 gas detector designed for accurate oxygen concentration detection in various environments. This air quality detector features a fast response time of ≤30s, thanks to its internal sampling pump and high-precision sensors from world-renowned brands, approved by third-party testing organizations.

Key features include:

  • The oxygen monitor is fast-responding, highly accurate and comes with a built-in sampling pump.
  • Switchable gas concentration units (PPM and mg/m3) with a single press.
  • Self-calibration and zero calibration functions for improved accuracy and reliability.
  • Easy restoration to factory settings with one press to avoid mis-operations.
  • Oxygen meter has multi-mode alarms, including light, sound and vibration, and can set alarm points to enhance user safety.
  • Extensive data logging capability with storage for over 100,000 sets of data, quickly accessible on the detector.
  • High-speed USB data transmission for efficient downloading to PC.
  • Long-lasting lithium polymer rechargeable battery providing 14 hours of continuous operation for toxic gases and 10 hours for combustible gases.
  • Durable high-intensity engineering plastic housing, suitable for various conditions and environments, with IP65 protection making it water-proof, dust-proof, and explosion-proof.

This detector is ideal for use in farms, livestock areas, liquid ammonia plants, public toilets, septic tanks, and other industrial applications.
