Overview

Description

XT-OPGD1000II / XT-OPGD1000II PRO open path gas detector is manufactured using high-performance photosensitive detectors and micro-controllers, combined with advanced SMD technology. It has good repeatability and temperature and humidity characteristics, as well as long service life and easy operation.

Applications

This gas detector is widely used in natural gas valve stations and storage stations, as well as in oil and petrochemical industries such as refineries, chemical plants, metallurgical industries, and power industries where combustible gases may be generated.

Features

High accuracy, stable performance, and long service life

3-wire 4-20mA analog signal output

3 relay outputs (low alarm, high alarm, and fault)

High performance LCD screen display, intuitive and clear

Using a magnetic rod/infrared remote control (optional) to operate the detector is easy to carry and operate

Professional matching installation brackets, easy and convenient on-site installation

Fast response, high sensitivity, only responsive to CH4, strong resistance to cross interference and water vapor

Measurement distance is maximum 100 meters

Supports Bluetooth function and can communicate data with portable instruments with Bluetooth devices

Equipped with remote upgrade function

Supports a Hart manual operator, which can perform parameter settings and query functions on the detector

Support external digital sound and light alarms
