JX-817 infrared spectrophotometer

Main feature

1. The electric modulation light source not only reduces the heating intensity of the light source to facilitate the heat dissipation of the system, but also simplifies the structure of the instrument and improves the reliability of the instrument by reducing the mechanical cutting motion device.

2. Real-time automatic zero adjustment, the computer not only collects the signal when the light source emits light, but also collects the signal when the light source is extinguished, realizing the zero-point real-time automatic adjustment, thereby simplifying the operation and improving the long-term stability of the signal.

3, the analysis efficiency is high, the instrument can complete the analysis and determination of one sample within 30 seconds (non-dispersive infrared method for 2 seconds).
