2. Use a threading tap to create a M10×1.5 thread in the hole.
3. Install the base of the cable gland in the hole and tighten with a 13 mm wrench.
4. Insert the seal of the cable gland in the base and place the nut of the cable gland over the
probe head.
5. Insert the probe head in the cable gland up to the black plastic part of the probe head.
Leave the black plastic part entirely outside the cable gland. Tighten the cable gland to
finger tightness.
6. Tighten the nut of the cable gland with a 13 mm wrench until the probe head stops
moving. Do not overtighten.

Vaisala HUMICAPâ Moisture in Oil Probe MMP8 enables fast and reliable measurement of
moisture in oil. It uses proven Vaisala HUMICAPâ sensor that was developed for demanding
dissolved moisture measurements in transformer and lubrication oils, hydraulic fluids, and
other liquids.
MMP8 measures dissolved moisture in oil in terms of the water activity (a
w
), relative saturation
(%RS), and temperature (T). Water activity or relative saturation indicate directly whether
there is a risk of free water formation. This data is relevant in lubrication oil applications where
detecting water ingress and preventing free water formation is crucial. The measurement is
independent of oil type and age.
