Overview
The Universal IV™ Series is the fourth generation RF continuous system built on Drexelbrook’s 50 years of experience in level measurement. The product is backward compatible with the industry standard Universal III™, Univeral Lite™, Universal II™ and RCT™ Series and is the ideal solution for a wide array of applications. A few enhancements to the Universal IV Series include worldwide hazardous location approval, standard display/keypad, autoranging capabilities and state of the art stable and accurate measurement.
Pro Model
The Universal IV™ Pro model integrates the RF Admittance technology pioneered by Drexelbrook with the versatility of Cote-Shield™ technology that ignores coatings on the probe and measurement span of 1" to 800'. The Pro is compatible with a vast array of applications: conductive, insulating, and heavy or light coating.

Lite Model
The Universal IV™ Lite model is the entry level RF Capacitance measurement system without Cote-Shield™ capabilities. Lite models can be used in non-coating conductive liquids and insulated coating applications where Cote-Shield™ is not required. In addition, the Lite model offers a measurement range up to 20' typically.
