YQ7 Multi-parameter Detection Alarm Instrument

I. Product Introduction

The YQ7 multi-parameter detection alarm instrument (hereinafter referred to as the “detector”) can simultaneously and continuously detect 7 parameters including CH4, O2, CO, CO2, H2S, °C, and m/s. It can also trigger an alarm when the parameters exceed the limit. The detector uses an 8-bit microcontroller as the control unit and employs high-precision detection components, featuring high sensitivity and fast response speed. The screen adopts a 3-inch color LCD, providing clear and reliable display. When the concentration of the gas to be detected in the environment reaches or exceeds or falls below the preset alarm value, the detector immediately issues an audible and visual alarm to alert us to take timely safety measures to ensure the safety of life and property. The detector has been reviewed and inspected by the designated national legal authority. The detector is suitable for all workers, including professional technicians, operators, and leaders.
