Valterra Horst Miracle Probes, For Black Water Tanks, Pack of 4, Carded

Sludge and soap residue build-up on the sides of RV black and gray water tanks can lead to false readings.  The sludge acts like a conductor between the positive content level sensors down the tank to the negative probe that is located at the bottom of the tank.  This will trigger the indicator panel to show that there is liquid level in the tank even when there is none.  The patented design of Horst Miracle Probes prevents similar false readings in the following ways:

– Horst Miracle Probes are considerably longer than standard probes and the sensor is surrounded by a Delrin body and teflon tube which prevents any liquid residue or sludge from setting up a conductive path

– The black tank probes have a specially designed “roof” over the probe sensor to prevent toilet paper from coming into contact with the probe and creating a false probe contact and related reading

Additional Features:

– Easy to install as they fit the 3/8″ diameter holes of existing probes

– Compatibility with existing wiring and monitors, so they can simply be connected to the new probes

– Available for both black and gray water tanks
