CTH1000 carbon monoxide detector intelligent carbon monoxide detector with high accuracy

CTH1000 Carbon Monoxide Detector Product Introduction

The CTH1000 carbon monoxide detector is an intelligent carbon monoxide detector made of electrochemical components. Using a microprocessor to process data, with high accuracy and functions such as undervoltage indication and automatic shutdown, it can continuously monitor the concentration of carbon monoxide in the ambient air, and has an over limit sound and light alarm; Continuous working time of over 150 hours, displaying the charging battery voltage during charging, and automatically stopping charging in case of overpressure. The tester adopts a high brightness LED luminous Nixie tube, which is very eye-catching and intuitive, small in size, light in weight, stable and reliable in operation, simple in operation and maintenance, and widely used in various occasions in coal mines to detect the concentration of carbon monoxide.

Structure and working principle of CTH1000 carbon monoxide detector

The CTH1000 carbon monoxide detector is composed of sensors, operational amplifiers, microprocessors, LED displays, alarm circuits, charging circuits, charging control, voltage stabilizing circuits, and other components. The carbon monoxide signal detected by the sensor is sent to the microprocessor for processing by the operational amplifier and then sent to the display to indicate the corresponding carbon monoxide concentration. When the concentration reaches or exceeds the set alarm point, the alarm circuit works and gives an audible and visual alarm. When the battery voltage drops to 3.75V, the undervoltage decimal point lights up (the last Decimal separator). When the voltage drops to 3.7V, the tester automatically shuts down.
