Infrared Gas Analyzer

Product Introduction

The Infrared SP4100 gas analyzer is a non-dispersive infrared (NDIR) gas analyzer, operating on the principle of selective absorption of infrared radiation by specific gases. The instrument features a single light source, single-chamber half-gas cell, and advanced series-type thin-film microphone detector. It boasts exquisite craftsmanship, high analytical precision, and excellent stability. Utilizing advanced digital processing technology and a new LCD display interface.

Product Features

1. German-origin NDIR gas sensor with high accuracy, long service life, and fast response; high-precision temperature control system eliminates the influence of ambient temperature fluctuations on measurements.

2. 4–20 mA analog output with a maximum load resistance of 750 Ω and extremely high accuracy.

3. Can be directly installed in a 19-inch rack for convenient operation; built-in precision filter effectively removes dust and impurities above 0.2 μm.

4. Automatic pressure compensation system eliminates effects of ambient pressure and flow variations.

5. Background gas interference can be corrected via static compensation or filtering gas cell, ensuring high measurement accuracy.

Application Fields

This product is widely used in industries such as industrial, agricultural, medical, and electronic sectors where real-time monitoring of gas concentrations like CO, CO₂, CH₄, SO₂, and NO is required.
