Accurate and stable measurements for any industrial application
  • IP65 rated housing provides corrosion-resistant protection
  • Graphically monitor measurement trends on LCD (display models only)
These transmitters provide reliable and long-term stability of humidity and temperature measurements. Select RH/temperature transmitters or universal transmitters — with or without a display. The RH/temperature transmitters measure relative humidity and temperature. The universal transmitters measure relative humidity, temperature, dew point, absolute humidity, wet bulb, mixing ratio, and enthalpy. Transmitters with a display provide both numerical and graphic measurement capabilities. The graphical display shows measurement trends and parameter history up to one year.
Integral Probe Transmitters are ideal for HVAC and condition monitoring applications. The 43/4”L x 1/2”-dia probe is directly attached to the housing and features a stainless steel filter.
Tight-Space (Duct-Mount) Probe Transmitters let you measure in remote installations and small spaces.
