COMPATIBILITY
Compatible Meters
The HI1286 electrode is designed specifically for Hanna HI 981401N and HI 981402 portable pH meters. The BNC connector ensures secure attachment, while the 2-meter cable provides flexibility for field measurements in water treatment facilities, agricultural operations, and general laboratory work. The PTFE junction resists clogging in demanding sample conditions where standard ceramic junctions may fail.
