Johnson Controls A99BB 200C Temperature Sensor Review

This was a replacement part, my last probe broke accidentally. Installation was easy (5 minutes) and the device worked again as before.

Works as expected. Checked the resistance with an ohmmeter and verified the accuracy against the table and thermometer. I bought it to use with a salvaged Johnson Controls 350 series temperature controller for a homebrew cabinet. Fast delivery.

This was a direct replacement for a sensor that was starting to register 184 degrees for my 55 degree pool. Needless to say, the thermostat didn't call for heat! The new probe was installed in a few minutes and works perfectly. Shipped on time and received quickly. Thank you!
