Review on 🌡️ Universal Digital PID Temperature Controller Meter Indicator with C/F Display, SSR Alarm Output, 40A Solid State Relay, and Thermocouple Probe with Heat Sink - Jaybva by Jason Cho

It works. The only thing I could ask for is another page of instructions explaining in more detail how to install the software. For example, the pulse width modulation period is short, about 1 second. This is good in systems with an electrical resistance heater controlled by a built-in solid state relay. Other loads such as B. a motor, but can perform better with slower shifting. Such geeky software details are not explained in the 2 pages of included instructions. That's a great price at $30.
