Description:
This portable AsH3 arsine gas detector is a professional safety measuring instrument for arsine high‑toxic hazard early warning. Arsine belongs to highly toxic electronic special gas, commonly found in semiconductor epitaxial process, special gas supply cabinet and non‑ferrous metal smelting workshops. Even low‑concentration inhalation of AsH3 will cause serious damage to human blood system, internal organs and nervous system, which may lead to life‑threatening risk. This detector is equipped with high‑stability imported electrochemical sensor, featuring fast response speed, low zero drift and stable measuring performance. It continuously collects and displays real‑time AsH3 concentration data of ambient air. When detection value reaches preset alarm threshold, sound‑light‑vibration triple alarm will trigger, reminding operators to cut off gas source, evacuate personnel and strengthen ventilation immediately. Adopting ergonomic lightweight handheld housing, it supports long‑time on‑site patrol and special gas equipment inspection. Adjustable alarm threshold and low power consumption satisfy daily safety inspection, environmental regular monitoring and emergency detection for semiconductor factories, special gas distribution stations and metallurgical sites.
Features:
Semiconductor technology of ultra low power 32 bit microprocessor, 24 bit ADC acquisition chip, so with the high accuracy.
2.4 inch IPS industrial grade color screen.
Support English language menu.
The gas concentration unit support for the ppm, mg/m3, %LEL, %vol.
With the inner pump and the suction strength is adjustable in different level.
Explosion proof grade of Ex ia IIC T4 Ga.
Function:
Inspect the gas concentration and alarm when it up to the preset alarm level.
With auto-test and data recover function.
One-key operation to restore to factory default setting.
Temperature and pressure compensation function.
Adjustable two stage audible-visual alarm threshold value.
Powered by rechargeable lithium battery with big capacity.
Working under the micro negative pressure is available.
Overload protection, over charge protection, anti static interference, anti magnetic interference, etc.
