Product Overview

OVERVIEW

 New 

UQ-100 series CH4 explosion-proof gas detector


It is suitable for use in various dangerous places and corrosive environments with strong acids and alkalis. It is wear-resistant and will not fade or peel off within 10 years.


UQ-100 explosion-proof CH4 gas detector is used for 24-hour continuous online monitoring of various gas concentrations on site and measurement of temperature and humidity. It can display concentration on site and sound and light alarms for exceeding standards, and transmit remote data.

A 2.5-inch high-definition color screen is used to display the concentration in real time. According to different detection gases, gas sensors based on electrochemical, infrared, catalytic combustion, thermal conductivity, and PID photoion principles, high-precision capacitive digital temperature and humidity sensors, HNAG1000 advanced circuit design, and mature core algorithm processing are used. Thus, a new generation of multi-functional fixed-online four-in-one gas detection detector that is currently leading in the industry was born.








Features

FEATURES

■Intrinsically safe circuit design, explosion-proof certification, secondary lightning protection, anti-static, lightning protection and anti-static capabilities exceed national standards, and can withstand high-intensity pulse surge current impacts. High reliability and stability. Anti-reverse connection design, any form of reverse connection will not damage the instrument.

■The standard infrared remote control can realize operations without opening the cover in dangerous situations, such as: modifying alarm points, concentration calibration, zero point calibration, silencer, factory reset, entering menu, viewing records, 4mA output, 20mA output (this function is required to calibrate other collection equipment).

■Chinese and English interfaces are selectable. The default Chinese interface supports free switching of gas concentration units. Conventional gases do not need to enter the molecular weight. Special gases will automatically calculate and switch after entering the molecular weight. The units are optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.

■The 2.5-inch high-definition color screen (LCM) displays real-time concentration, time, temperature, humidity, storage status and other information. It can detect 4 to 6 gas concentrations and temperature and humidity at the same time. The menu interface uses high-definition simulation icons to display the function names of each menu, and concise Chinese or English operation prompts.

■Three display modes can be switched: displaying multiple gas concentrations at the same time, large fonts cyclically displaying single-channel gas concentration and real-time curves, automatically or manually switching between channels, setting whether to display the maximum value, minimum value, and gas name, and viewing historical record curves.

■Automatically tracks zero point to prevent drift, temperature compensation, multi-level calibration, and can comply with national standards and local and provincial metrology bureau standards in various regions.

■Data recovery function and concentration calibration misoperation automatically identify and prevent, which can avoid defects caused by improper operation.

■It can record calibration logs, maintenance logs, troubleshooting countermeasures, sensor life expiration reminders, and next concentration calibration time reminder functions.


Application fields

Petroleum, chemical industry, medicine, environmental protection, flue gas analysis, air management, tunnels and other occasions that require fixed installation and online detection of gas concentration.
