This BARBEN ANALYZER TECHNOLOGY pH SENSOR BAT-2 546-1-B is in great condition and is guaranteed to be fully functional. This sensor came from a local lab that had surplus inventory. We urge customers to view all photos as they show overall condition, included accessories and useful information. Please feel free to contact us with any questions. Design: Wetted materials include; CPVC, Wood, Porous TEFLON, VITON, and Glass. Maximum Pressure, pH, Temperature Ratings: 1 - 13 pH, 0 - 1000C, 150 psig. Longer lasting performance, minimal maintenance, and customer convenience. The General Purpose CPVC sensor can be used in either threaded insertion or submerged applications, using a 3/4? MNPT thread at both the top and bottom of the sensor body. Extreme Duty AIP Reference (Patent Pending): A large multi-segment solid-state reference permanently infused with potassium chloride (KCL), separated by a series of Axial Ion Path Sealing Rings, out performs the competition in longevity and resistance to poisoning Features: CPVC body, AIP reference with Viton sealing rings, general purpose pH glass measuring electrode, Flush Porous TEFLON liquid junction, dual notch tip protection, thermocompensation - 3k ohm Balco or PT100 RTD, and a flexible Hi-temp, Lo-loss TPE jacketed cable. BAT-1 with Pt100 utilizes all tiinned leads, the BAT-2 provides a BNC connection for the measuring electrode and reference and tinned leads for the temperature compensation unit.
