TEMPERATURE CONTROLLER DIGITHERMO OT-9

Digital Setting / Digital Display

DIGITHERMO OT-9

This temperature controller is small but high-quality, equipped with heater friendly PID control.
Evolved from previous model (OT-3) , this controller has timer/alarm/communicating function, supporting two types of sensors.
OT-9 can widely support temperature adjustment needs.
