HANNA HI99131 Portable pH/Temperature Meter for Plating Baths with HI62911D pH Probe, pH Range: pH -2.00 to 16.00, Temperature Dual Range: -5.0 to 105.0°C/23.0 to 221.0°F

HI 99131 is a waterproof, portable pH and temperature meter, ideal for use in plating baths. HI 62911 double junction pH electrode (included) utilizes the proven recessed flat tip technology for long-life. The recessed flat tip is easy to clean and prevents solids in solutions from collecting on the sensor. The titanium body functions as a potential matching pin for more stable readings and an extended sensor life. The probe tip incorporates an annular PTFE junction that maximizes surface contact, and enhances response and stability. Additionally, the integral temperature sensor eliminates the need for an external temperature probe. A mini amplifier to boost the electrode signal, rendering the meter impervious to noise and interferences.The meter reads from -2.00 to 16.00 pH, while simultaneously showing the temperature in °C or °F. Graphic icons guide operations and a stability 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 inaccurate readings due to low voltage and an 8 minute auto-off feature saves battery life.
