Very nice write up!I still think Ranco is a great thermostat. They can be set to 1 degree differential which I hardly consider inaccurate. I know they are made for HVAC but we have cold boxes at work which store Acetaldehyde. Ranco's control the temperature in the boxes. Acetaldehyde has a boiling point of 68 degrees and is stored in sealed containers. This means if a Ranco fails the containers stored inside would start exploding!
