HI-96749 Chromium VI Portable Photometer, Low Range information

Hanna's extended description

Chromium VI, Low Range Portable Photometer

The meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell.

At normal temperatures chromium is corrosion-resistant. For this reason, it plays an important role in the plating industry as well as cooling towers. In addition, it has certain qualities that make it useful in the production processes of the textile industry.


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.
