Thermistor Calculator
Below is the Capgo Thermistor Calculator.
The calculator is initialized with calibration coefficients
of the popular YSI 44004 thermistor
To use it you need a browser that supports Java applets.
The calculator is multifunctional
and bidirectional, allowing you to:
 select your preferred temperature units
 select a predefined thermistors by
manufacturer's part number OR
 calculate the calibration coefficients
from three calibration points OR
 direct entry of the calibration coefficients
from manufacturer's data
 calculate the temperature from the
thermistor's measured resistance
 calculated the thermistor's resistance
from its temperature
Comments:
The calibration coefficients correspond to a, b and
c in the Steinhart & Hart equation:
T = 1 / ( a + b.ln(R) + c.ln(R)^{3})
where the temperature T is always converted
to degrees Kelvin and the resistance R is in ohms. When using the calibration
feature of the calculator, ensure the temperatures of the three calibration
points are approximately equally spaced, and cover the range over which
the sensor will be used.
Note, the calculator uses the values as seen on the display.
The output is rounded to 0.1°C and 0.01 Ohms, so when an output is
subsequently used as an input, the result will reflect this rounding

it may be a little different to the original input.
