HI 98183 is a waterproof, portable meter designed for demanding applications. HI 98183 measures pH/ ORP and temperatuare.

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's 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 out the pH probe for an ORP probe to obtain mV readings in the ± 2000 mV range.

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 200 samples. This data can later be transferred to a PC with the USB connection and HANNA' s HI 92000 software. “ 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.

A backlit, graphic LCD provides easy to read resolution even in low-lit areas. A combination of dedicated and soft keys allows easy, intuitive operation in a choice of languages. Comprehensive GLP data are directly accessible by pressing the GLP key. Access the contextual Help Menu to obtain on-screen information and assistance about each feature at the touch of a button. Designed for field use, these instruments can be operated with one hand and are supplied in a rugged carrying case. With an extended battery life of up to 200 hours, users are assured long operation. The inductive charger can either be plugged into a standard 115V socket with the included adapter or a 12 VDC source, such as a car' s 12 V accessory outlet.
These meters come equipped with the HI 72911B pH/ temperature electrode with rugged, titanium casing.
