Does anyone know how to calibrate the thermometer? My thermometer is reading ice water as 106 degrees F! Any help would be awesome. Thanks in advance.

The only thing I could contribute would be it sounds like you either have old batteries, or, maybe there's a glitch and removing the batteries for a moment then putting them back in may reset the unit.

Im in the HVAC field and have compared temps using other digital thermometers to this one, and its right on the money. There are also calibration screws for both leads. The directions recommend using a glass of ice water and calibrating it to 32F or 0F. Nice little unit. Batteries last a long time. Durable construction. And a useful magnetic hangar on the carrying case.

I didn't calibrate mine. I haven't compared it with other thermometers, but it seems to be working just fine.

I believe you have the thermometer reading in Celcius instead of Fahrenheit. Check the upper right hand corner to See if there is a C of F displayed. To change the scale, When you turn on the unit hold done the button until you see the hourglass. The thermometer will change.

As I may have mentioned in the review, in ice slush it measures 32F and is also spot on with the predicted boiling temp at the elevation of Abq (200F) but that varies slightly with weather. I'd guess +/- one degree, but have just the one sample and no AST certified thermometers with which to compare.

I did not "calibrate" my oven thermometer I just just the Admetior in the middle of the oven. Heated it to 350. Checked they were the same. 20 minutes later I checked again and they were the same. I can't really read my oven thermometer anymore, but at least I know it works.

You have to calibrate it. It was beyond me. But i had a friend who'd done well in chemistry. He was unsuccessful in getting a reading that made sense, but I blame that more on him, than the reader. I would look for a pre-calibrated meter for someone with limited tech skills. i needed it to test PH in pond water. I have several mud ponds. The PH is a little different in each of them.

In order to calibrate such a probe, the manufacturers would have to add a calibration potentiometer to the circuit. Without opening up mine I doubt it was made for field calibration. You can test the accuracy of the device by filling a 8 oz glass with ice and water. Allow to set for 3 to 5 minutes and insert the probe. That water ice mixture should be 32 deg F. what your device shows should be considered where 32 is. That means if your device shows 29 you are off by -3 deg. this should not be a big deal a plus or minus 2 degs. Also, as the battery degrades, it will affect accuracy. Test your probe once a month and replace battery based on any drifting away from what you started out. I have used these types of probes for many years in hvac and they fail long before I lose accuracy.

The top button is your answer, sounds like it might be faulty. I'm sure you've already tried to just take it out and unplug it and let it sit an hour or so then 1) put it back in the water for 20-30 minutes, 2) plug it in and set the temp. I love mine - and 78 works for my Beta but it will cycle through the choices just fine. I like the way it blinks at a different temp to show actual water temperature.

Yes. I put the probe tip in ice water and got the reading down as low as 35° F. Just don't get the entire probe wet or it will short out.

Yes. The procedure to recalibrate the thermometer is on the back of the original packaging. It involves slushy ice water, letting the thermometer reading get down to correct reading, etc. I don't have my package with me here at work, so cannot walk you through it step by step. If you no longer have your packaging, contact me again and I will retrieve the information and get it to you.

Depends what you mean by accurate, since there are no numbers on the dial. I suggest getting a thermometer and testing the temps. On mine, the temperature I want for green tea is just slightly lower than the range of the green section, but I like the water cooler than most people want. Once you test it a few times, you will know what the dial range is, and you can get pretty close temps without measuring every time.

Hi Brent, I've just opened one of them up, and the answer is no. There is no off set or gain potentiometer that would allow a calibration. I have been using temperature devices for years, and I have to have them calibrated annually. I have never had a 0.5C thermocouple be out out of spec--only an RTD one that goes to hundredths of a degree. They typically do not go bad or drift (unless damaged). Regards, Daryl

As far as I know, no you can't, of course you can test the unit you get with ice and boiling water, its what I did just to double check. Seems to be a pretty straight forward out of the box thermometer.

You can adjust the temperature ("calibrate") by up to 270F up or down, read the manual to learn how to do it. In your case, you will adjust from 362F to 250F, i.e. 112F lower than shown.

I have not measured it with a thermometer, but if the spacing on temp markings on the thermostat are consistent it would be trying to keep a temp of about 150 degrees F. However, the the temperature readings when measured seem to run hot and be somewhat uneven across the surface.

yes dear Hippychick it says on the front of the package that it is Recalibratable. The instructions for recalibration are pretty simple. Using ice and water. i have been very happy with my Thermometer.
