Measurements are precise within 1 percent, with a max resolution of 0.1°F/°C.
Users can adjust high and low set points to take advantage of the thermometers robust alarm function. The 42509 offers an audible alarm to alert the user when the measured temperature falls above or the below the High/Low range.
