Hanna HI 98171 Waterproof Portable pH, ORP and Temperature Meter
With Cal Check® and 5-Point Calibration

HI 98171 is a state-of-the-art, heavy-duty portable pH/ORP meter with temperature sensor. Housed in a waterproof casing, this unit is specifically designed to provide laboratory results and accuracy under demanding industrial and field conditions. It comes equipped with a series of new diagnostic features - dramatically improves a measurement's reliability. Up to 5 calibration points - choose from 7 memorized buffers and 5 custom buffers - provides the user with the flexibility necessary to adjust the calibration range and obtain the most accurate and precise readings possible. Exchange out the pH sensor for an ORP sensor to obtain mV readings; adjustable between two ranges and accurate to +0.1 mV. The signature Calibration Check® features an electrode condition graph which alerts the user with regards to the electrode status during calibration. And if readings are taken too far outside the calibration range, the unit will warn the user with a graphic signal. Users may set a reminder to notify when calibration is due. HI 98171 is equipped with auto-end measuring mode that ensures readings are taken only when they are stable. Instantly accessible GLP data via a dedicated GLP key. Log-on-demand will hold up to 150 records. All data can be downloaded to a PC via the RS232 connection. With up to 200 hours of extended battery life, the unit will guarantee long operation in the field.
