The good old mercury thermometer, as cheap as can be. remains the reference. I can put all the ones I have in a bucket and they always all concur.
I have a heater that is set to 70 and the tank is maintaining a good 76 and more during seasons.
Depending on how the heater is installed the settings on the thermostat, the resulting temp in the aquarium can vary a lot. A good way to have a good compensation is having a slightly overkill heater in a area with the greatest water movement.
Avoiding to create hot spots is key. The longer it runs when heating and the longer it stays off between uses, the better.
