pH Meter for Boilers and Cooling Towers - Rugged steel body electrode
- Easy operation
- Accurate and precise pH readouts
HI 99141 is a water proof, portable pH/temperature meter, specifically designed for boiler & cooling tower applications. HI 72911 double-junction pH electrode (included) has an unbreakable titanium body and a flat tip. The electrode also features an annular PTFE® junction for maximum surface contact, giving increased response and stability. The titanium cage of the probe functions as a shield and adds to the sensor's life. The flat tip is easy to clean and prevents solids in solution 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 and 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 of 8 minutes saves battery power.
HI 99141 is supplied complete with HI 72911 pH electrode with internal temperature sensor, pH 4 and pH 7 buffer sachets, HI 700661 electrode cleaning solution (2 x 20 mL), batteries, rugged carrying case and instructions.
