HI-96725 Chlorine, Cyanuric Acid and pH Portable Photometer information

Hanna's extended description

Chlorine, Cyanuric Acid and pH Photometer for Legionella protection



The HI 96725 measures 4 parameters that are crucial in monitoring for preventive maintenance or disinfection.

Offering high levels of accuracy as well as being water resistant, portable and easy to use, it makes it the optimum solution for quick, efficient and economical measurement for Chlorine, Cyanuric Acid and pH.

Legionella species is the agent that causes human Legionnaires' disease as well as the lesser form, Pontiac Fever. Transmission is facilitated by the inhalation of mist droplets containing the Legionella bacteria.

Common sources of Legionella include cooling towers used in industrial cooling water systems as well as in large central air conditioning systems, domestic hot water systems, fountains, and similar disseminators that draw from a public water supply. Natural sources include freshwater ponds and creeks.

Since Legionella is especially harmful to people with weakened immune systems, it should be actively checked for in the water systems of hospitals and nursing homes.

Key features


  • Clear display messages make the instrument quick and easy to operate.
  • The powerful Cal Check calibration function means that there is no need to return the instrument to the laboratory to check its efficiency. Samples can be checked and validation confirmed at the press of a button.
  • Positive locking system ensures the cuvette is located in the same position each and every time is it placed in the measurement cell.
  • Auto shut off feature turns meter off after 10 minutes of non-use to save battery life.
  • Fully water resistant
  • Clear easy to use function buttons
  • Direct readout of parameter measured

Designed for precision


With the Hanna calibration check validation function, users can verify the performance of the meter quickly and easily at any time. Using Hanna NIST traceable standards, it takes just a few moments to check the accuracy of the instrument and to recalibrate as and when necessary.

All new instruments are factory calibrated at source and the electronic and optical design of the Hanna photometers minimises the need for frequent calibration. The Hanna calibration check further minimises the frequency with which instruments need to be returned to the calibration laboratory for full servicing.
