Description
HI 99100 and HI 991002 meters from HANNA instruments® offer IP 67 waterproof protection in a compact casing. The included electrode has a built-in temperature sensor and amplifier, to render 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 from -5.0 to 105.0 °C or 23 to 221°F. HI 991002 also measures ORP in the ±1999 mV range.

These meters have a stability indicator and hold feature that prompts you when to take the reading & freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations.

The battery life of the meters guarantee over 1500 hours of continuous use. At startup, they perform a self-check and then display the percentage of the remaining battery level to assure proper working condition. Calibration is performed automatically at 1 or 2 points using standard or NIST buffers.
