This versatile thermometer has a wide temperature range and 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's accuracy is NIST traceable and in each temperature range the 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.
When probes are connected to inputs 2 and 3, the difference between the probes is displayed to 0.01°C. Linearization is centered at 40°C. Because the BAT- 10 has such high accuracy and sensitivity, measurements accurate to 0.01°C can be made around this point. Repeatability, which is most important for this type of measurement, is 0.01°C.
BAT- 10 is supplied with a non-linearized analog output suitable for most chart recording applications. This output is directly proportional to the reading on the display.
