SC-DEW - Humidity/Temperature Controller
This humidity controller has been designed for wet/dry bulb humidity applications. It comes factory precalibrated to suit 385 RTD input, and features dual 4-20mA analogue output and a dual display for temperature and R.H.
- Dual 3-wire RTD input (385/392, Pt100). Suits wet/dry bulbs
- Dual display for simultaneous viewing of humidity and temperature
- Dual analogue output (4-20mA)
- Simple, intuitive interface with scrolling text prompts
- Factory precalibrated for 385RTD. Two point recalibration (no input signal needed)
- Security PIN protected calibration and setpoint access
