1 Product description：
Portable Single-Gas Personal Detector works in a continuous way of detection of toxic gas concentration, as intrinsically safe equipment, it’s suitable for explosive hazardous places.
2 Features and benefits：
Key component failure detection function, monitor the normal working condition:
Low consumption, long standby, rechargeable lithium battery design.
Normal detection power consumption is less than 500μA
Battery power consumption 650mAH
Sustainable at least 50 days (24 hours a day).
No power consumption if off
Temperature compensation function:
Ensure accurate measurement over the entire operating temperature range.
Display the field temperature
Zero adjustable setting and full scale calibration without open it
With low/high limit, STEL and TWA etc. alarm functions, easily rewrite the alarm point
Sound, light, vibration 3 kinds of alarm
Silence function
LCD display, continuously shows real-time gas concentration, background light automatically open
