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 sensor for an ORP sensor to obtain mV readings in the +2000 range. HI 98184 includes direct ion concentration readings for ISE's and measures in ppm. The ion charge or nominal slope can be entered manually. Press Auto-Hold while measuring and once stabilized, the current reading will remain displayed for your convenience in documenting. Or switch to log-on-demand mode and record and save up to 300 samples. Return to the lab and download all data to your PC with the USB connection and Hanna's HI 92000 software. OUT OF CALIBRATION RANGE WARNING can be engaged to alert the user in the event that a reading is taken too far from the calibration's periphery.

 

HI 98184 is supplied with HI 72911B combined pH/Temperature electrode, pH 4.01 and pH 7.01 buffer solutions; (4) 1.2V AA, 1300 mAh rechargeable batteries; HI 710042-01 inductive battery charger with power adapter; rugged carrying case and instructions.
