Techne hand-held Model 4400 Series Ultra-High Accuracy Thermometers take extremely accurate temperature measurement to the laboratory, the production floor, and the field.

Ultra-high thermometer accuracy up to ±0.015°C is achieved because the thermometer uses extremely stable. The 4400 System uses coefficients for the Probes with the Stienhart-Hart algorithm to calculate the exact temperature reading every time you plug in a probe to take a measurement.
