246/247 BFT Backflow Tester Barton's Back Tester offers the best in accuracy, durability, and reliability in portable backflow preventer test kits. These kits utilize the time proven Barton 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 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. |

Acuating Unit The foundation of Barton's Tester is the Model 224C Differential Pressure Unit. This proven unit has been used by Barton 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 DPUs. |
