1-Point Calibration
Water-Saturated Air
1. Remove the storage cap from the top of the
calibration chamber and replace it with the vented
calibration cap.

2 Vented calibration cap
2. Place the sponge wafer in the bottom of the
calibration chamber and saturate with approximately
10 mL water.

5. Allow 5 to 10 minutes for temperature stabilization
prior to starting the calibration procedure. Do not
leave the instrument in the calibration chamber for
more than 30 minutes. This can allow condensation to
form on the sensing material, which will produce false
low readings after calibration. If condensation does
occur, remove the instrument, dry the sensing
material, place the instrument in the chamber, and
calibrate.
3. Gently dry the instrument and sensing material with a
paper towel, making sure there is no water or debris
on the instrument or on the sensing surface.
4. Place the instrument into the calibration chamber
about 2.5 cm (1 in.) above the water-saturated
sponge.

2-Point Calibration
100% and 0% Saturation
1. Set up the calibration procedure as previously
described, and perform a water-saturated air
calibration.
2. Remove the water-saturated sponge from the
calibration chamber and fill the chamber to the fill line
with approximately 60 mL of fresh sodium sulfite
solution.

2 Temperature sensor
2. Place the instrument into the solution. Leave at least
13 mm (0.5 in.) between the surface of the sensing
material and the bottom of the chamber.
3. Ensure that the temperature sensor is completely
submerged in the solution.
4. Allow at least 5 minutes for the temperature to
stabilize prior to performing the calibration procedure.
5. Once calibration is complete, remove the sensor, and
thoroughly rinse to remove all of the sodium sulfite.
