Hanna Instruments HI 9125N Portable pH/mV Meter, with Enhanced Design

The Hanna Instruments HI 9125-01 is a waterproof, portable pH, temperature and oxidation reduction potential (ORP) meter for indoor and outdoor use. The meter features a large dual-level LCD screen, with a graphical interface that provides calibration instructions. Temperature compensation and pH calibration are automatic, with five memorized buffer values (pH 4.01, 6.86, 7.01, 9.18 and 10.01). The meter comes with the HI 1230B combination double-junction, gel-filled pH electrode, and the HI 7662 stainless steel temperature probe with 1 m (3.3') cable. The meter can also be used with ORP electrodes (sold separately). The HI 9125-01 has a range of -2.00 to 16.00 pH (+ or - 0.01) with a resolution of 0.01 pH. Temperature range is -20.0 to 120.0 degrees C/-4.0 degrees F to 248.0 degrees F (+ or - 0.4 degrees C/+ or - 0.8 degrees F) with a resolution of 0.1 degrees C/0.1 degrees F. ORP range is + or - 699 mV; + or – 1999 mV with accuracy + or - 0.2 mV; + or – 1 mV and resolution 0.1 mV; 1 mV. Input impedance i...
