Product description
The HK8 NIR-LED-H2O-Meter uses a unique NIR-LED technology to precisely measure the moisture in various materials. The device works on the principle of reflection measurement, in which the diffuse NIR light analyzes the water molecules in the product. It is particularly noteworthy that the HK8 does not use color filters with a filter wheel or halogen lamps, which results in a more stable measurement. The drifting of the measured values, as is often the case with other NIR systems, is fully compensated.
Thanks to its modular design, the HK8 can be used flexibly, whereby the sensor and the evaluation unit can be installed separately. This enables installation even in places that are difficult to access. The sensor is installed above a wide variety of products to be measured, such as bulk materials (sand, cement, gypsum, etc.), textiles or paper webs.
The Specter8 software enables simple and user-friendly calibration. Up to 8 calibrations can be stored in the device, which increases the versatility of the device for different applications.
What sets the HK8 apart
