pH Meter for Boilers and Cooling Towers

The new 50-HI99141 is a waterproof, portable pH/temperature meter specifically designed for boiler & cooling tower applications. 50-HI72911 double junction pH electrode (included) has an unbreakable stainless steel body and a flat tip that is made of fluoride resistant glass. Hanna's fluoride resistant glass is a special type of glass developed to stand up to concentrations of fluoride found in water, which would destroy standard glass pH sensors. The electrode also features an annular Teflon® junction for maximum surface contact giving increased response and stability. The stainless steel body 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 -2.00 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.
  • BEPS (Battery Error Prevention System) prevents bad readings due to low voltage and an auto-off period of 8 minutes saves battery power.
