Note: Volumes of liquid as low as 1/4 tsp (1.24 mL) can also be tested with the Small
Volume Test Kit Accessory. Contact your C-Therm representative for more information.
Step 2 - Place the sensor into the beaker.
Slowly slide the sensor into the liquid at a slight angle so that bubbles do not form on the sensor’s
surface. If the liquid is a highly viscous material, waiting may help to ensure stability if bubbles are
entrained in the sample.
Step 3 – Perform the test.

Blotter or Thin Sample Testing
When testing thin materials, meaning samples with less than the recommended minimum
thickness or with high k filler materials, it is necessary to confirm that the heat wave from the
sensor is not passing completely through the sample. This is accomplished by performing a test
with a blotter material and overlaying voltage time curves from test results taken with and without
the blotter material. If there is a deviation point between the two curves, the samples must be
stacked or a custom calibration performed with shorter timing parameters.

Step 1 – Place the sample on the sensor.
Use a contact agent if necessary.
Step 2 – Place the blotter material on the sample.
If available, use the foam or polymer reference material. Otherwise, use any available piece of
low k material (foam, wood, plastic).
Step 3 – Place the weight on top of the blotter material.
Step 4 – Begin the test.
Step 5 – After 4 measurements, pause the test.
Step 6 – Remove the blotter material.
