Hello, I have a PinPoint remote thermometer that seems to read high. I've sent it back to be calibrated and it kept the same temperature as the other thermometers I'm using to check it then after a few weeks it seems to be about 2.5* high. I have another digital brand along with 4 different regular thermometers through the tank and sump to make sure I'm getting a fair representation. This is the second time this has happened. Does anyone have experience with this? Thanks.
