What does everyone out there use to calibrate your temperature controller? This all started because I noticed my Hanna salinity checker is consistently 1 degree below what my controllers say. Here are my options:
So, where would you set the controller in this case? I’m not going to buy some crazy expensive instrument over a possible 1 degree variance.
- The controller itself.
- Cheap glass thermometer that came with a 20g tank: 72 degrees. So that’s useless.
- Infrared thermometer from a local hardware store: agrees with the temperature controller.
- Hanna salinity checker: consistently 1 degree below the controller.
- Seneye: 1.2 degrees below the controller.
