Coralife Digital

Help my thermometers are confused!?

I just bought a second Coralife Digital Thermometer yesterday with the aim of water changes. Would the test so I put back into the tank. 84.2 The new registered! My father read 78.2. Do not go with the new by the former has been underway for some time. It is said that these thermometers are + – 1.5 f, so that is only 3 degrees. Should I go with the new? Could the previous low Cell? I think I I'll take because I put new batteries in the old and still the same bed. I'll buy a mercury float. There is more logical that the new service because I have my heater was 78.

I will be the new more reliable. The old equipment when it does is not replaced in time, and the team did not tend to last as we believe. If you want to prove that, replace the batteries former. If you still get a reading, you can buy third. So if your two new read the same, you can throw the old and now 2 new replacements. If the thermometer is in the third phase with his former grade 78, you know how to repay the second purchase defective. (If this happens, and threw the receipt, use the receipt of third thermometer to return the second, because the same product.)
