Moisture Meters


IM Series Infrared Multi Analyzer

The IM series is an on-line multi IR wavelength analyzer utilizing infrared absorption technology for measuring product constituent and/or thickness. Signal processing capabilities are built into the compact, Stand-Alone detector unit for easy installation and operation. A maximum of 99 calibration curves can be stored into the detector memory for numerous measurement applications. The detector can be used by itself or connected to a PC/plant control system, as both analog and digital outputs are provided. A remote setting display unit, connectable up to 9 detector units, can be used to set various detecting parameters and also displays measured values.

Up to 10 wavelengths, able to measure 4 constituents, moisture, film-thickness, organic properties, and coating-thickness in real time.
Communicate with multi interface, RS-485 (MODBUS), Ethernet (LAN) (option)
High-speed (28ms) & High-repeatability.
Multi-calculation function.
Self-diagnostic function, easy maintenance.
Conforms to CE standards and IP-65.
