This is a digital thermostat with easy ON-OFF and PID control. The switch with breaker, SSR (solid-state relay) and terminal block are all integrated.
Since this thermostat features a self-tuning function, it will tune itself even when the control amount is affected by vibration due to some disturbance... which settles (stabilizes) vibrations in the control amount, providing an exceptionally accurate temperature reading.
The thermostat can be easily operated on screen via a personal computer, thanks to its onboard communication functions.
This makes it useful as a basic data logger or for saving temperature data collected to hard disk.
