Product Details
Product Overview
The HM-ZHS1 is an online near-infrared moisture analysis system that measures the moisture content of moving material continuously and without contact. Water molecules absorb near-infrared energy in specific bands and absorb most strongly around 1.45 μm and 1.94 μm; within that spectral range the absorbed energy is proportional to the water content of the material. The instrument selects wavelengths with optical filters, converts the returned infrared light into an electrical signal with a photoelectric detector, and displays the result as a moisture percentage.
The system is mounted on a conveyor or in a process line and reports moisture while the material is still running, so that process adjustments can be made without waiting for laboratory sampling. Detection is non-destructive and the probe never touches the product. The HM-ZHS1 uses a 4-band, 8-path optical design intended for materials with uniform texture, stable colour, even particle size and small process fluctuation. Measured results can be uploaded over Wi-Fi or Ethernet to a self-developed cloud data platform that is provided to users free of charge.
Key Features
- Non-contact, non-destructive measurement: the probe reads the material from a working distance of 250 ± 50 mm, so the moving product is neither touched nor destroyed.
- Dual-detector measurement: the main detector and the auxiliary detector compare the infrared signal of every wavelength one by one, so the output signal relates only to the substance being measured and instrument drift is effectively eliminated.
- Multiple onboard temperature sensors: secondary compensation for the slight temperature drift of the two detectors, together with monitoring of the whole system so that each component keeps working normally.
- 4-band, 8-path optical design: a mature and stable optical configuration that meets the requirement for continuous, accurate measurement under normal working conditions.
- Imported high-efficiency halogen light source: high efficiency and long service life, which reduces maintenance cost.
- Imported high-detection-efficiency detector: improves the signal-to-noise ratio of the system and makes the data more reliable.
- Fast response: the filtering range can be set between 0% and 2.5%, a single measurement takes only seconds, and the result is output quickly, which suits rapid screening of large batches on line.
- Android 10 operating system with a 7-inch, 1024 × 600 touch screen: a clear and efficient interface for operation, model work and data review.
- User-built quantitative models: users can take representative samples of their own material and build, validate and maintain the calibration model with the built-in software.
- Free cloud platform: results can be uploaded over Wi-Fi or Ethernet to a self-developed data management platform that is open to users at no additional cost.
- Automatic alarm: low-limit and high-limit alarms with queryable alarm records.

Model Selection
| Model | Optical configuration | Intended material and working conditions |
|---|---|---|
| HM-ZHS1 | 4 bands, 8 optical paths | Continuous and accurate measurement under normal working conditions, on materials with uniform texture, stable colour, even particle size and small process fluctuation |
| HM-ZHS2 | 7 bands, 14 optical paths | Materials with colour variation, dark colour, slight caking, mottled surface or complex composition, and demanding measurement environments |
Both models share the same host, probe, operating system, interface configuration and 200 detection channels. They differ in the optical design and in the material conditions the optical design is intended for. The optical path diagram among the product images above illustrates the wider 7-band, 14-path configuration of the HM-ZHS2; the HM-ZHS1 described on this page uses the 4-band, 8-path optical design.
