BX171 Disposable Portable Gas Detector

Detailed Product Description

Portable Gas Detector Description
BX171 is a disposable portable single gas detector that can detect H₂S, CO and O₂ with small size and firm configuration. It is mainly intended for individual used to detect a confined space or the working environment where dangerous gases existed and harm to personal safety. It is normally clipped on belt, lapel or breast pocket. 
It can be widely used in the oil and gas industries, steelworks, chemical plant, mining,marine, power plants, sewage treatment plant, environmental protection, city construction, labs etc.

Electrochemical Sensor Principle

1. Principle:

Using the active chemical properties of the gas to be measured, it has reducing or oxidizing properties. In the process of participating in the chemical reaction, electrons are released or absorbed. A large number of electrons form a current. The current size is proportional to the gas concentration. The concentration of the gas to be measured can be measured by measuring the current size.

2. Advantages:

The performance is relatively stable. Most toxic and harmful gases can be measured by electrochemical sensors, and the measurement linearity is very good.

3. Disadvantages:

Electrochemical sensors are consumables with a relatively short service life. The service life is 1-2 years in general environment, and needs to be replaced every 3-6 months in harsh environment. The maintenance cost is relatively high.

4. Use:

It is mainly used for the detection of toxic and harmful gases.
