IR-M1000 Series - Moisture Meters

The IR-M1000 Series is reflection system on-line moisture meters utilizing the infrared absorption of moisture. Converting capabilities are built into the compact designed detector unit for easy installation and operation. Maximum 99 calibration curves can be stored into memory for many applications. The unit can be used by itself or by combining with personal computers as an analog output and a communication function are provided with. A setting display unit connectable with maximum 9 detector units can set various kinds of setting items of the detector unit and displays moisture value.

Features

Built-in converting capabilities
The converting capabilities are built into the small, lightweight and compact detector unit.
Measurement with high-speed and high sensitivity
By high-performance CPU and improved optical components, high speed (output renewal cycle: 28ms) and high sensitive measurement can be performed.
Setting display unit
The setting display unit has a front panel of 96 x 96 mm and can connect with up to 9 sets of the detector unit. The communications interface between the setting display unit and the detector unit is by RS-485.
Protective structure conforming to IP-65
The enclosure of the detector unit and the front panel of the setting display unit conform to IP-65 for severe atmospheric condition.
CE-marking
CE-marking models are available.
