HI-96750 Potassium Portable Photometer information

Hanna's extended description

Potassium Portable Photometer

The HI-96750 uses the Tetraphenylborate Method. The reaction between potassium and reagents causes turbidity in the sample.

Potassium as a chemical element is commonly found in nature. It is present in soil and drinking water and is also an essential element for the growth of plants and animals.

Potassium concentration is important in determining the quality of soil in many greenhouse, agriculture and horticulture applications. Potassium salts are also a common component of fertilisers.

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.
