HMK15 with HMP3, HMP4, HMP5, HMP7, and HMP8 probes
Before inserting the probe head in the salt jar, remove the filter and inspect the sensor
element. If the leg pins of the sensor are longer than 7 mm (0.28 in), attach the 211302SP
calibration adapter. This prevents the sensor from being submerged in the salt solution.
Composite sensors typically have long leg pins.
211302SP is the longer of the two adapters included with HMK15. With this adapter attached,
use the 13.5 mm hole on the salt jar cover.

12 mm (0.47 in) diameter probes where the leg pins are shorter than 7 mm can be inserted in
the salt jar without an adapter. Note that you can still use the 218377SP calibration adapter to
fit a 12 mm probe in the 13.5 mm hole. This allows you to have multiple probes inserted in a salt
jar at one time.
Sensors on the probe head are vulnerable to damage when the
filter is removed. Handle the probe carefully and avoid touching the sensors.
CAUTION!
