CheckTemp® Digital Thermometer

The Mack Truck of Digital Thermometers

CheckTemp® Digital Thermometer We recently came across an  old CheckTemp® Digital Thermometer in an out of the way location.  Looking at the serial number, we could tell that it was at least 10 years old.  We turned it on and it was ready to measure temperature right away.  A quick cross check showed accuracy right on specification.

That is what you can expect if you buy this time tested instrument.  It has a minimum of controls, so there is zero training.  It is accurate.  But, best of all, it lasts and lasts.  If you have had problems with durability of digital thermal probes in your operation, give the CheckTemp a close look.

In keeping with the theme of simplicity and durability, the CheckTemp batteries are easy to access and change.  There are separate °F and °C models, so no confusion there.  Just flip the on switch and start using.
