Features & Applications:

This Hanna waterproof pH / temperature meter is specifically designed for high-temperature environments. Graphic icons assist in measurements, making results easy to read and this meter easy to use. The double-junction pH electrode (included) has an unbreakable titanium body and a flat tip and features an annular non-stick coated junction for maximum surface contact which provides increased response and stability. The probe's titanium sheathing functions as a shield and adds to the sensor's life. The flat tip sensor is easy to clean and prevents solids in solutions from collecting on the sensor. This advanced electrode also contains an integral temperature sensor and a mini amplifier to boost the electrode signal, eliminating the effects of noise and interference.

The meter reads from -2 to 16 pH, while simultaneously showing the temperature in °C or °F. Graphic icons guide operations. An instability indicator with hold feature determines when to freeze the reading for easy record keeping. Calibration is performed automatically at one or two points with standard or NIST calibration buffers. Battery life is over 1500 hours and at startup, the LCD shows the remaining battery power. In addition, BEPS (Battery Error Prevention System) prevents bad readings due to low voltage and an auto-off period at 8 minutes saves battery power.
