OC-905 pump suction portable H2 hydrogen gas detector, high precision hydrogen monitor with sound-light alarm, for hydrogen plant, hydrogen energy station and pipeline leakage safety detection.
Description
OC-905 portable pump-suction hydrogen gas detector is a handheld gas monitor with built-in sampling pump. It adopts high-precision H2 sensor to quickly and accurately detect hydrogen concentration on site. LCD screen displays real-time gas data, and sound-light alarm will trigger when concentration exceeds preset threshold. Compact handheld design supports mobile field inspection for hydrogen leakage safety monitoring.
Function:
Inspect the gas concentration and alarm when it reaches preset alarm level.
High accuracy, good stability and good repeatability, long working life.
One-key operation to restore to factory default setting.
Adjustable two-stage audible-visual alarm threshold value.
Powered by rechargeable lithium battery with big capacity.
The built-in pump, stable flow rate, can be opened or closed;
Feature:
Multi Gas Detection: Supports combustible gas, oxygen (O2), carbon dioxide (CO2), toxic gases and TVOC
Built-in Pump Sampling: Stable flow rate (300ml/min) for fast and accurate detection
High Precision Sensors: Imported sensors with intelligent algorithm and temperature compensation
Audible & Visual Alarm: Dual alarm system with ≥75dB buzzer and LED light
Data Storage & Export: Stores up to 100,000 records, USB data export supported
Explosion-Proof Design: Certified Ex ib IIC T4 Gb for hazardous environments
Long Battery Life: Rechargeable lithium battery, up to 12 hours operation
