· S230 For Low Dew Point Applications
The S230 Dew Point Transmitter provides accurate results of a range down to -100 °C Td. This makes it perfectly suitable for special applications where a low dew point needs to be measured.
· Ex Areas Solution
The optional IECEx approval makes it the perfect tool to be used in explosive environment (Ex area). SUTO’s unique dual sensor technology optimizes sensor sensitivity and accuracy by automatically selecting the ideal sensor type for the situation.
· User-Friendly Output Signals
The S230/S231 come ready to use and simple to install with your choice of 4-20mA or Modbus RTU (RS485) outputs. If required, parameters can be quickly monitored through the SUTO service software. The transmitters can also be connected the SUTO S331 (stationary) or S551 (portable) data logger and the data can be transferred for further analysis.
