Domestic HCHO detector 4160-II detector 4160-19.99

Description :

4160-II domestic HCHO detector is the cost-effective choice for indoor HCHO detection

4160-II type detector product overview:

The 4160-II detector is composed of an imported American INTEASCAN electrochemical sensor and a central processing unit. The electrochemical sensor is a highly sensitive detection probe, with a sensitivity 20-200 times greater than that of a diffusive sensor. It is very sensitive to detecting low concentration gases in indoor environments and can detect very low volatile gases in indoor air.

The INTEASCAN electrochemical sensor from the United States is a unique electrode sensor that does not require an independent reference voltage, has a unique gas storage chamber, can return to zero in polluted environments, has a long service life (5 years), and is maintenance free.

The gas is sucked in by the gas pump and comes into contact with the sensor storage chamber and the sensitive electrode of the electrochemical sensor, and undergoes an electrochemical reaction to output a stable electrical signal. The electrical signal is processed by the central processor, and the gas concentration value can be accurately displayed on the LCD screen in numbers.

The 4160-11 detector adopts a 3800mA large capacity lithium-ion rechargeable battery, which can measure continuously 50 times. The operation is simpler, and the sensor can automatically return to zero in polluted indoor environments. It can be widely used as a specialized equipment for indoor environmental detection, indoor environmental governance, environmental decoration, chemical engineering sites, and scientific research and teaching.

The main features of the 4160-II detector are:

1. The 4160-11 detector uses the standard unit ppm;

2. Can return to zero in polluted environments;

3. Electrochemical sensors have an ultra long service life of over 5 years;

4. Electrochemical sensors are maintenance free and do not require water injection for maintenance;

5. The sensitivity of electrochemical sensors is 200 times greater than that of diffusive sensors; Lower concentrations of molecules can be detected,

6. B-TEST mode can detect the service life of electrochemical sensors;

7. The electrochemical sensor of the 4160-11 detector is a unique two electrode sensor that does not require an independent reference voltage or battery power supply;

8. The instrument automatically monitors the capacity of lithium-ion batteries during operation to prevent over discharge of the batteries;

9. Adopting DC8.4V, 3800mA large capacity lithium-ion rechargeable battery, it can measure continuously 50 times;

10. Adopting imported American INTEASCAN electrochemical sensors and central processing units, domestically assembled and easy to maintain;

To summarize the above characteristics, compared with the American 4160-2 detector, the domestically produced 4160-11 detector has more superior features, lower prices, and can replace it
