EST-301-CO Carbon monoxideTesterIt is aFixed gasConcentration measuring instrument，useHigh precisionCircuit design, using original imported sensor chips as the core, afterWanyi TechnologyDevelopment calibration, signal amplificationCalibration, rigorous testing，Only then was it given to the factory.

instrumentDesign and produce according to relevant national regulationsStandard:

EST-301-CO Carbon monoxideTestermainused for：

1. Gas storage leakage monitoring
2. Indoor environment detection Indoor natural gas, coal gas, and carbon monoxide detection from smoking.
3. Underground parking car interior environment detection Measurement of carbon monoxide produced by automobile exhaust emissions.
4. Coal, metallurgy, and petrochemical industries Carbon monoxide is a product of incomplete combustion of carbon containing substances such as coal and petroleum. It is a colorless, odorless, and non irritating toxic gas
5. Other environmental testing agencies

EST-301-CO Carbon monoxideTestermain features：

1. Explosion proof safety chamber design, in compliance with IEC60079Electrical explosion-proof requirements; Aluminum explosion-proof shellHas good sealing, corrosion resistance, long life, low temperature resistance, resistance to sulfide and silane gas poisoning; Suitable for use on offshore platforms, as well as in various harsh environments such as high temperature and high humidity.
2. Adopting advanced imported sensors with high precision, long service life, repeatability, and stability.
3. Automatic recognition of sensor probes, which can use sensor probes for different types of gases; After replacing the sensor probe, the program automatically recognizes and obtains parameters such as gas type, range, low point alarm value, and high point alarm value.
4. Equipped with backlit LCD, on-site display of concentration values, on-site and remote maintenance settings do not affect the control unit; The non-contact method of magnetic induction completes calibration and parameter setting.
5. Four special highlightsLED lights, respectively indicating power, low, high alarms, and function prompts, with programmable low and high alarm action values; At the same time, the sound alarm will sound and inform the on-site staff of the time.
6. Simultaneously possessing numbers/Simulate two types of signal outputs, with the analog signal being a standard three wire 4-20mA current signal;The digital signal isRS485， It is very convenient to communicate with the upper computer.
7. A password can be set to enter the menu to prevent other personnel from operating or changing parameters at will, ensuring safety and reliability.
