traceable accuracy
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.

Differential Measurements
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.
Analog
Output
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.
