OC‑905 Handheld PH3 Gas Detector with inner pump, high‑precision electrochemical sensor, triple alarm, data log & USB export, for grain silo, chemical plant, fumigation site phosphine leakage monitoring.
OC-905 Portable gas detector with inner pump
Description:
OC‑905 handheld phosphine gas detector adopts built‑in pump suction sampling for fast and accurate phosphine (PH₃) concentration detection and leakage inspection. Equipped with high‑precision electrochemical PH3 sensor, it delivers rapid response and stable measurement performance. Clear high‑definition screen displays real‑time gas concentration data. Audible, visual and vibration triple alarms activate immediately once readings exceed preset safety thresholds. Built‑in large‑capacity rechargeable battery supports long‑time continuous field operation. It supports data logging and USB data export for on‑site record keeping and post‑job data analysis. Compact handheld structure, dust‑proof and explosion‑resistant design adapts to harsh industrial working environments.
Features:
Used the original imported sensor, semiconductor technology of ultra low power 32 bit microprocessor, 24 bit ADC acquisition chip, so with the high accuracy.
2.5 inch dot matrix display interface.
All English operation menu and easy operation.
Unit data available for LEL, VOL, ppb, ppm and mg/m3.
The circuit installed the four layers of wire, so well anti-interference.
Explosion proof grade is Ex ib IIC T4 Gb.
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 could be controlled.
