This is a single toxic Gas Detector with exquisite appearance and portable pocket; user-friendly display with backlight at the same time, which is convenient for viewing the indicated value in dark environments; 360° multi-function alarm and easy operation, saving users time and operating costs. Strong and durable, especially suitable for workers with toxic and harmful gases on site. This series of Gas Detectors can be used to detect more than 30 kinds of gases such as H 2 S, CO, O 2 , SO 2 , HCL, CL 2 , NO 2 , H 2 , NH 3 . (Please refer to the detailed model for details)
It adopts plug-in electrochemical sensor, which applies the principle of constant electrolytic potential method. Its structure is to place three electrodes in the electrolytic cell, namely, the working electrode, the counter electrode and the reference electrode, and apply a certain polarization Voltage. The outside world is separated, and the measured gas passes through the membrane to the working electrode , and a redox reaction occurs. At this time, the sensor has an output current, which is proportional to the concentration of the poisonous gas. After sampling, the current signal becomes a Voltage amplification, Then through the conversion circuit , the Voltage signal is converted into a current signal, and the corresponding gas concentration is displayed on the screen through the display screen.
The machine is small in size, light in weight , and easy to carry; vibration alarms of different frequencies can easily distinguish the alarm status it has adjustable secondary instantaneous alarms and TWA, STEL alarms ; The normal operation of the sensor and the battery, and the automatic zeroing after power-on ensures the accuracy ; the built-in sound alarm can reach 95 decibels, and there is also a bright LED flashing light that is clearly visible within 10 meters of the light alarm; And precise temperature compensation function.
