4500 High Accuracy Smart Probe Thermometer

The Model 4500 Series Ultra-High Accuracy Thermometer takes metrology-level temperature measurement to the laboratory, the production floor and the field.

Ultra-high system accuracy is achieved because the thermometer and probe function as if they were calibrated together as a system even though they can be purchased separately. The 4500 System uses coefficients stored in each probe with the Steinhart-Hart algorithm to calculate the exact temperature reading every time you plug in a probe to take a measurement.

The 4500 series thermometers accept a wide range of plug-in probes equipped with proprietary Smart Probe system. The probes utilise super stable thermistors capable of providing high resolution, fast response and ultra high accuracy.
