Product Details

Product Introduction

KQ-O2 single point wall mounted oxygen alarm is a fixed instrument that can continuously detect gas concentration in the working environment.

KQ-O2 is a natural diffusion method for detecting gas concentration, using imported electrochemical sensors with high accuracy, accurate measurement, anti-interference, stable performance, high sensitivity, and fast reaction time;

KQ-O2 uses a large LCD screen to display the real-time concentration value of leaked gas. If it exceeds the preset alarm point, it will immediately activate the sound and light alarm signal or drive the exhaust system; International Standard

The 4-20mA output signal can be directly connected to the factory DCS system, and the RS485 digital signal is connected to the factory upper computer; The instrument adopts embedded microcontroller technology, with a simple Chinese menu operation, complete functions, high reliability, and overall performance leading in China.

KQ-O2 has been widely used in fields such as aquaculture, tunnel construction, fire protection, coatings, greenhouse cultivation, and agricultural production, and has become an essential protective equipment in industrial safety production.

Main features:

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

◆ 128 * 64 dot matrix ultra large LCD display

Users can set their own high and low alarm points

◆ The all Chinese menu is convenient for domestic users to use

◆ First alarm time display function

◆ Equipped with real-time clock function

◆ replaceable modular sensors

◆ Simple calibration function to reduce measurement errors

◆ Automatic storage of 1000 alarm records

The backup battery can work for more than 24 hours in non alarm state (optional for users)

Standard 4-20mA output signal can be directly connected to the factory DCS system (optional for users)

Standard RS485 digital signal connected to the factory's upper computer (optional for users)
