Use the Best
For over 50 years, Drexelbrook has established itself as the world’s leader in capacitive based water cut measurements.

Easy Calibration - Now with Built-in LCD Display and Keypad
All Universal IV CM comes from the factory pre-calibrated and requires only one point validation.

IECEx Approvals
The Universal IV CM Model has been approved for both Ex ia and Ex d installations.

Our Perm-A-Seal sensing element does not require epoxy coatings that wear out and require expensive servicing.

Eliminate Routine Maintenance
The Universal IV CM (Cut Monitor) is built upon the Drexelbrook expertise in RF Admittance that allows the electronics to ignore paraffin and other coatings that buildup on the probe.

0-50% in Light Oil & 0-80% in Heavy Oil
The Universal IV CM comes factory pre-calibrated to one of 11 pre-set ranges, for Light Oil (API Gravity > 25) and Heavy Oil (API Gravity < 25)

Cote Shield™
The proven Cote-Shield is designed into the Universal IV CM series and enables the instrument to ignore a pre-determined length of the sensing element.
