The comparative chart below clearly shows that a Checktemp 1 thermometer is the wisest choice for your routine temperature measurements. Checktemp 2 is a high accuracy thermometer with a Teflon coated, folding 110mm long probe. The folding probe allows multiple angles for measurement in difficult places. The Teflon coating enables Checktemp 2 to stand up to the harmful effects of chemicals. The probe utilizes a high-tech NTC thermistor sensor to measure the temperature.
Thermistors make it possible to obtain extremely high accuracy in a very short period of time.
Checktemp 2 is available in C and F models. World's First Calibration Check Feature Glass thermometer users do not worry about their thermometers' accuracy because the method of measurement is physical liquid expansion. The largest problem associated with electronic thermometers is the stability of the circuitry that measures the temperature. For this reason users are hesitant to trust electronic thermometers. To overcome this, a calibration test device has been incorporated into the meter.
