PH meter
Hanna Instruments

HI 98185 is a fine precision waterproof pH/ORP/ISE and Temperature Meter in HANNA's high-end portable series. A backlit 128 x 64 pixel graphic LCD provides high-quality resolution in this hand-held instrument. This meter comes equipped with the technologically advanced combined pH/temperature electrode, HI 72911B . Choose from 7 standard buffers and 5 custom buffers to obtain up to 5 points for calibration and achieve high precision readings with an accuracy of 0.001 and resolution up to +0.001. HANNA's signature Calibration Check® maintains a calibration history and monitors the pH electrode and buffers during calibration; while the electrode's condition is continuously displayed during measuring mode.

Exchange out the pH/temperature electrode for an ORP sensor to obtain mV readings in the +2000 range. HI 98185 has auto recognition of 15 different ISE sensors and can be calibrated with up to 5 points and 6 standard buffers (choice of units). This unit allows an extensive choice of measurement units (ppm, ppt, g/L, ppb, ug/L, mg/mL, M, mol/L, mmol/L, % w/v, user) and has an expanded measuring range of 1.00 x 10-7 to 9.99 x 10-10.
