I have the original Apex Gold that I bought brand new about 2 years ago.
I had it on my frag tank and worked perfectly. Moved it over to another tank and the Temp setting read 30 degrees F. Tried to calibrate it, but it only lets me calibrate the temperature between 5.9 and 35.9 F. Figure I had a bad probe, so I ordered another one.
Plugged in the brand new probe and same reading. Still only able to calibrate it up to 35.9 F. I switched it over to Celcius and it reads 1.6....
Any suggestions????
