Innovative Handheld Digital Thermometers TEGAM's 820 Series Thermometers are easier to use, more accurate, and provide more functions than any competitive unit at any price, including Fluke's 50 series. Easy to use because every function is controlled by its own accessible front panel key. Easy to understand because the status of every function is shown on the display. Easy to program because one touch of the user friendly keypad changes TC type from K to J to T. One touch changes °F to °C. One touch begins or ends min. max. data recording, views recorded data, or holds the display. It's easy to repeat procedures because the unit retains the functions you've selected even when turned off. The dual input models allow you to view T1, T2, or T1 minus T2, or to continually scan all three modes. Their six data logging registers automatically record the minimum and maximum temperatures of all three modes simultaneously. These thermometers are more accurate, with accuracies of 0.1 % and a resolution of 0.1 ° full range in °F and °C. You get fast, accurate and repeatable readings, and an unmatched two year calibration guarantee to prove it.
