BAT-12 Microprobe Thermometers

We designed the world’s first thermocouple thermometer, Model BAT-4, in 1969. It soon found uses in the lab, factory, hospital O.R. and in the field. The new BAT-12 has improvements for all these applications:

Bat-12 Microprobe Thermometers

In the lab: Readings to 0.1° C; near perfect stability.

In the field: A superior “cold junction reference” which maintains accuracy with ambient temperature changes from O°C to 50°C; sealed construction, carrying case.

For recording: Analog output for strip chart recording is a standard feature.

BAT-12 is the ideal instrument for use with microprobes. These 5 sensors are among our most popular and there are many more to choose from:

Flexible Implantable Microprobe, IT-18
Needle Micropbrobe, MT-26/2
Surface Probe, BT-1
General Purpose Probe, HT-1
Sensor Six Pack, PT-6

BAT-10 Microprobe Thermometers

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.
