1,Overview
The YQ7 multi-parameter detection alarm instrument (hereinafter
referred to as the "detector") can simultaneously and continuously
detect seven 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 detected gas 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.
