Barton/Cameron 246/247 BFT Backflow Tester

246/247 BFT Backflow Tester

Barton/Cameron's Back Tester offers the best in accuracy, durability, and reliability in portable backflow preventer test kits. These kits utilize the time proven Barton/Cameron welded beryllium copper bellows assembly for one-half of one percent accuracy. This translates into an accuracy reading within 0.075 PSID in both ascending and descending actions. Barton/Cameron offers the perfect blend of accuracy and durability without compromising functionality. Both models can be easily connected to any reduced pressure backflow preventer or pressure vacuum breaker.

Barton/Cameron Acuating Unit

Acuating Unit

The foundation of Barton/Cameron's Tester is the Model 224C Differential Pressure Unit. This proven unit has been used by Barton/Cameron for over 60 years for products such as: indicators, recorders, integrators, transmitter, switches, and controllers. Stability of calibration and minimum maintenance are inherent qualilties of Barton/Cameron DPUs.
