Hanna HI 98184
The Hanna Instruments HI 98184 is a waterproof, portable meter designed for demanding applications. This meter measures pH/ORP/ISE and temperature. Choose from 7 standard pH buffers and 5 custom pH buffers to obtain up to five point calibration and achieve high precision readings with a pH accuracy of ±0.002 and up to ±0.001 pH resolution.
Hanna Instruments Calibration Check maintains a history of past calibrations and monitors the pH electrode and buffers during subsequent calibrations for any signs of wide calibration variances due to a dirty or broken electrode or contaminated pH buffers. In measurement mode, the electrode's percent condition is continuously displayed.
Exchange the pH probe for an ORP probe to obtain mV readings in the ±2000 mV range. The HI 98184 adds direct ion concentration readings for ISE's and the results are diplayed 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. Switching to log-on-demand mode allows users to record and save up to 300 samples. This data can later be transferred to a PC with the USB connection and Hanna's HI 92000 software. The 'Out-of-calibration-range' warning can be engaged to keep the user informed of the current calibration and helps to avoid taking measurements that are out of range.
