S230 / S231 Dew Point Sensor (-100 … +20 °C Td)

The SUTO S230/S231 Dew Point Sensors provide reliable dew point monitoring for industrial and hazardous applications. SUTO’s unique dual sensor technology optimizes sensor sensitivity and accuracy by automatically selecting the ideal sensor type for the situation.

Useful: measure down to -100 °C Td
Precise: advanced QCM sensor technology
Integrated: easy setup with SUTO data loggers

Description

The SUTO S230 / S231 dew point sensors provide reliable, long term stable dew point monitoring for hazardous industrial applications. SUTO’s unique dual sensor technology automatically selects between two sensors included in both the S230 and S231, providing higher levels of sensitivity and accuracy. The S230 / S231 comes ready-to-use with your choice of 4-20mA or Modbus/RTU (RS485) outputs. If required, parameters can quickly and easily be configured through the SUTO service software.
