Our Hygrocontrol Type 83 Hygrometer was constructed for critical relative humidity and stainless steel are available in different lengths and diameters.  Analog current calibration over RS 232 3V. There are several different sensor filters available.

• Moisture meters with the highest accuracy for mea­suring relative humidity and temperature in enclo­sures with protection class IP 65 with fixed probes.
• Various probe tubes (from PP to stainless steel) are available, including pressure-proof for operation pressure + vacuum. 
• Measured values are relative humidity and tempera­ture. 
• Microprocessor-controlled measurement and cali­bration.
• Linear measurements outputs for humidity.
• Readings of humidity and temperature is also via CAN-BUS available (Type 84).
