ZT-100 Water In Oil Monitor

ZelenTech ZT-100 Water In Oil Monitors are designed to detect water contamination in virtually any kind of oil or fuel. It works with diesel, heavy fuel oil, engine lubrication oil, gear box oil, hydraulic oil, turbine oil, vegetable oils and many more.

Our meters comes in where water content levels are, or can be expected to, exceed saturation levels and therefore renders Saturation Meters unusable. With a ZT-100 you can measure way beyond the saturation point of the oil. ZelenTech ZT-100 Water In Oil Monitors are excellent for monitoring lubrication and hydraulic systems in heavy machinery and ships.

Dedicated versions are available for Vegetable Oil / Palm oil as well as for Water In Fuel Injection (WIFE)

Most other applications can be handled by our generic versions. Contact us for help in choosing the correct version for your task
