HANNA HI991001 Waterproof Portable pH/Temperature Meter with Extended Range, pH Range:pH -2.00 to 16.00, Temperature Dual Range: -5.0 to 105.0°C/23.0 to 221.0°F

The HI 991001 portable pH meter from HANNA® offers IP 67 waterproof protection in a compact casing. Supplied complete including a rugged carrying case and a unique titanium body pH electrode that has a built-in temperature sensor. The electrode (included) 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 from -5.0 to 105.0°C or 23 to 221°F. This pH meter has 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 features graphic symbols that guide you through all operations.The battery life of the meters guarantees over 1500 hours of continuous use. At startup, the meter performs 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.
