HI-96711 Free and Total Chlorine Portable Photometer information

Hanna's extended description

Designed to measure the free and total chlorine content of water, the Hanna Photometer for Free and Total Chlorine is ideal for use in the production of a wide range of products.

Offering high levels of accuracy as well as being water resistant, portable and easy to use, this meter is hugely popular with operators across the food, laboratory and water industry.

A measurement range of 0.00 to 5.00 ppm free chlorine makes it the optimum solution for quick, efficient and economical chlorine measurement. Where it is necessary to measure total chlorine as well as the amount of free chlorine in the water, the HI-96711 offers a perfect two in one solution.

This model also offers and extended range of 0.00 to 5.00 ppm making it ideal for testing even smaller concentrations of chlorine.

Ideal for
  • Food: quality of water used in salad washing processes
  • Laboratory: plastics, paints, solvents, medicines, antiseptics
  • Water: measuring free chlorine content in water samples

  • 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
  • Calibration check solution available - HI 96711-11

  • 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.

    NB: reagents ordered separately.

    Significance of use

    As one of the oldest and most common forms of disinfection, chlorine improves water quality by destroying disease-producing micro-organisms and by reacting with other organic and inorganic substances. Chlorine levels must be actively monitored to ensure sufficient chlorine is present for disinfection, as well as to control adverse effects such as taste, odour, and potential reactions with organic matter to form harmful disinfection by-products.

    Battery powered – Allows use away from a power source. Batteries are included with all battery operated products.

    Water Resistant – Can withstand temporary exposure to water, but should not be submerged or washed under running water.
