Features & Applications:

This Hanna water resistant pH / ORP / temperature meter features a backlit 128 x 64 pixel graphic LCD provides high-quality resolution in this hand-held instrument. Choose from 7 standard buffers and up to 2 points for calibration, and take measurements with a resolution of 0.01 and accuracy of +0.01. 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 probe for an ORP probe to obtain mV readings in the +2000 range. 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 200 samples. Return to the lab and download all data to your PC with the USB connection and Hanna's HI 92000 software.

The 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 periphery. A combination of dedicated and soft keys allows facile, 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, this instrument can be easily operated with one hand and is housed in a rugged carrying case. With an extended battery life of up to 200 hours the user is assured of a long operation time. The inductive charger can either be plugged into a standard 115V socket with the adapter included or a 12 Vdc source, such as a car's 12 V accessory outlet.
