ULTRA™ THERMOMETER ACCURACY
Ultra™ thermometers are tested at selected test points to be within tighter than normal tolerances to assist in
providing improved accuracy. Other points will not necessarily fall within the same accuracy as those found at
the selected test points, but will be within an accuracy of ±1°C.
