Moisture measuring instrument HK8-mini

near-infraredLEDfor food applications

Unique NIR- LED technology • continuous online moisture measurement • no moving parts • specially designed for continuous online measuring of moisture/ TS in liquid products in pipes or tanks • in large pipes or tanks the sensor is penetrating the product. On small pipes the sensor is flanged on a sight glass • Color has no influence on the measured signal • no maintenance • easy to use calibration software The HK8-mini is a device for continuous NIR reflection measurement with infrared LED's. The NIR-H2O-Meter is a modular unit, evaluation and sensor system are mounted in different housings. The distance between the sensor and the evaluation unit can be up to 50 meters. The HK8-mini is a further development of our proven HK8. It was specifically designed to dive into large pipes or to be flanged via a sight glass on a small pipe. The measured value of the H2O content is available as digital (RS232, optional RS485) and analogue value (0/4-20mA). Advantages: In contrast to conventional IR- or NIR-systems of other suppliers, the HK8-mini is not equipped with colour filters or halogen bulbs. The used LED illumination cares for an improved stability with a lifetime of 10 years. Measurement Design: The sensor is either completely inserted into the product (flange in large pipes or a tank), or attaches through a sight glass. Depending on customer requirements, the fitted sight glass or HK8-mini sensor can be equipped with borosilicate glass or sapphire.
