The new BAT-10 is the most versatile thermometer we have ever designed. Wide temperature range and extensive choice of probes can be used in applications as diverse as cryogenic measurements for blood banking and cryosurgery, skin temperature measurements in exercise experiments, liquid measurements in spectrophotometer cuvettes, melting points of plastics and all types of animal and insect temperature measurements.

BAT-10 accuracy is NIST traceable and in each temperature range accuracy is the same as the resolution. For instance, in the 0.1°C range, accuracy is 0.1°C (± 1 least significant digit). Few digital thermometers will do this.

In most instruments there is a difference of several tenths between specified accuracy and resolution. At physiological temperatures, where minute changes can be critical, the differential range allows readings to 0.01°C with 0.01°C accuracy.
