Product Details

YD-812N fixed dichloromethane gas detector with display

Product Overview

Our company's intelligent gas detector uses natural diffusion to detect gas concentration, and adopts imported catalytic combustion sensors and infrared sensors with excellent sensitivity and repeatability; LCD or LED digital displays suitable for factory applications display the concentration value of leaked gas in real time, and immediately activate a light alarm signal when it exceeds the preset alarm point; The international standard (4-20) mA signal can be directly connected to the factory DCS system; The instrument adopts embedded microcontroller technology, with simple operation, complete functions, high reliability, and overall performance leading in China.

Main functions

The instrument adopts advanced 16 bit ultra-low power embedded microcontroller

LCD display (two-wire detector) or LED digital display (three wire detector)

Users can set their own high and low alarm points

Automatic calibration function to reduce measurement errors

Important operations require password verification to effectively prevent accidental operations

The standard (4~20) mA signal can be directly connected to the factory DCS system
