Fluval digital thermometer

Hi all I’ve recently purchased this fluval thermometer as I had the basic glass one before hand just wondering how accurate these are as my old one currently shows 26 degrees Celsius thanks.

Sorry - I’ve never used this brand, but most digital thermometers are relatively accurate.

This one doesn’t have a remote probe though? It reads through the tank wall? Those are inherently less accurate due to variation in tank wall thickness.

The best thing to do would be to confirm its accuracy with a known accurate thermometer.
