The Hanna Instruments HI 991001 and HI 991002 meters have IP67 waterproof protection in a compact casing. The included HI 1296D pH electrode has a built-in temperature sensor and amplifier which renders your measurements impervious to noise and electrical interference. The large display shows readings in an extended range from -2.00 to 16.00 pH and simultaneously shows temperature in °C or °F. The HI 991002 also measures ORP in the ±1999 mV range.
The Hanna Instruments HI 991001 and HI 991002 meters have a stability indicator and hold feature that prompts the user to take the reading and freezes the display for easy and accurate recording. The meters use extensive graphic symbols as guides through all operations. The battery life of the meter guarantees over 1500 hours of continuous use.
At start-up a self-check is performed remaining battery level displayed to assure proper working condition. Calibration is performed automatically at one or two points using standard or NIST buffers.
The Hanna Instruments HI 991001 and HI 991002 ship complete with HI 1296D pH electrode with internal temperature sensor, pH 4 and pH 7 buffer sachets, HI 700661 electrode cleaning solution, batteries, rugged carrying case and instructions.
