4500 High Accuracy Smart Probe
Thermometer
The Model 4500 Series Ultra-High Accuracy Thermometer take metrology-level temperature
measurement to the laboratory, the production floor and the field.
Ultra-high system accuracy, ±0.015°C , 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 utilize super stable thermistors capable of providing high resolu-
tion, fast response and ultra high accuracy.
