Touch-type Online Infrared Moisture Analyzer NIR Moisture Meter Real-time Infrared Moisture Test Machine

Working Principle

1. The hydrogen-oxygen bonds in water molecules absorb near-infrared light of specific wavelengths. At this specific wavelength, the energy of the reflected near-infrared light is inversely proportional to the energy absorbed by the water molecules in the material. The moisture content of the measured material is calculated based on the amount of energy loss.

2. When water molecules are excited by a specific energy band, they become vibratory. This band is particularly strong for water molecules in the near-infrared region of the spectrum, and the instrument is also easier to implement in terms of energy emission, filtration, and reception.

3. Near-infrared measurement technology is a non-destructive, non-contact, real-time measurement technique.

Structural Features

• Employs a single-sensor, five-wavelength detection method, significantly improving stability compared to six-beam or eight-wavelength methods.
• Five wavelengths provide more reference wavelengths, enhancing measurement stability and accuracy.
• Average testing accuracy reaches approximately 0.1%-0.5% (depending on the material being measured), meeting production process requirements.
• Enables online dynamic real-time detection with a response time of only 8ms, achieving real-time control of product moisture content.
• Highly integrated electronic components and SMT-technology circuit boards result in low failure rate and stable, reliable quality.
• Smaller filters than traditional brands, less affected by bandwidth limitations.
• Single lead sulfide sensor avoids linearity issues associated with dual sensors.
• Dynamic real-time diagnostic system, requiring no regular maintenance.
• Multiple output signal options: RS485, 4-20mA analog signal, and USB interface.

Functional Features

1. Non-contact, using infrared technology to measure moisture through diffuse reflection.
2. Multi-channel configuration: The moisture analyzer has 50 channels, numbered 1-50. Each channel number represents a set of channel parameters. Changing the channel number selects different channel parameters to accommodate the measurement of different types of materials using the same instrument.
3. Minimal impact from external light variations: Features automatic temperature compensation, ensuring excellent long-term stability despite temperature changes.
4. Simple installation and quick operation: Installation and commissioning do not disrupt normal production. The moisture analyzer uses pre-calibration; on-site calibration only requires adjusting the intercept (zero point).
