DA-800-VOC

Introduction
DA-800 detects various combustible, toxic and VOC gases leaked from industrial areas and display its density for gas producers, gas users, gas reservoirs, gas by-producers, and so on.
It is an indicator and transmitter type gas detector which converts detection signal into a standard current signal and transmit output to external devices.
Transmitter of DA-800 displays sensor¡¯s current and voltage signal by gas density on LCD, still converts into 4-20mA standard current output signal and transmit to external side.
4-20mA standard current output signal can be transmitted to various controller such as Gas leakage alarm system (GMS1000, GMS2000) PLC, DDC, MMR to build a integrated or individual gas monitoring system.
Features
Built-in micro processor realizes various artificial intelligent functions which result in more convenient, more accurate, and more efficient gas detection environment.
Built-in HD(high dissolution) A/D converter for accurate output signal.
LOW/HIGH 2 step relay contacts (AL1/AL2) enable to interlock with a various external devices like FAN.
4-20mA output enables stable and long distance (maximum 2.5km) signal transmission.
User programmable Menu offers to set user¡¯s own operating functions.
