Raytek MI3 series is the latest release from the world leader in infra red temperature measurement. The replacement for the highly successful MID series has many improvements and extensions to the range. There are digital transmitters for 4 or 8 heads, giving very low costs per measured point, and there is an OEM head that can be integrated to PLCs or digital controllers directly.  Cables can be cut to length and are available from 1 to 30M lengths. The new digital heads have low temperature coefficient, are rated to 120C,(option 180C) IP65, and retain their calibration - allowing hot swapping of heads.

There is a full range of mounting and protection accessories such as air purge, window assemblies and brackets. Digital Communications can be RS485 Serial, Modbus, or Profibus in different models. 1 micron and 1.6 micron high temperature units listed separately.
