The Michell Instruments SF82 Dew Point Transmitter is designed for control of dew point
and moisture content in compressed air dryers to maximize energy efficiency. The SF82
is capable of providing fast, accurate dew-point measurements down to -60°C (-76°F) dew point.

The SF82 uses proven thick film measurement technology coupled with sophisticated
microcontroller electronics to provide accurate and stable measurement across the
transmitter lifespan. It is available with a range of process connections and electrical
connectors for easy installation.

M12 5-pin connector version enables the SF82 to output 4 to 20mA and Modbus RTU over RS485 outputs.
