The HI96711 Free and Total Chlorine Portable Photometer combines accuracy and ease of use in an ergonomic, portable design. A user can accurately determine the concentration of free and total chlorine in a variety of water samples within a 0.00 to 5.00 mg/L (ppm) range using ready made reagents. The HI93701-01 reagents are used for free chlorine and the the HI93711-01 are used for total chlorine measurements. The HI96711 offers many advanced features including the exclusive CAL Check™ function used for performance verification and calibration of the meter.
  • CAL Check™ Validation and Calibration
  • Built-in Timer
  • Automatic shut off

Details

The HI96711 portable photometer is for the measurement of free and total chlorine. Hanna's portable photometers feature an advanced optical system; the combination of a special tungsten lamp, a narrow band interference filter, and silicon photodetector ensure accurate photometric readings every time. The Hanna exclusive CAL Check feature utilizes ready-made, NIST traceable standards to verify both meter validation and calibration. The exclusive cuvette locking system ensures that the cuvette is inserted into the measurement cell in the same position every time to maintain a consistent path length.

Features at-a-glance

CAL Check - Allows for performance verification and calibration of the meter using NIST traceable standards.

GLP - Review of the last calibration date

Auto-shut off - Automatic shut off after 10 minutes of non-use when the meter is in measurement mode. Prevents wastage of batteries in the event the meter is accidentally not turned off.

Battery status indicator - Indicates the amount of battery life left.

Built in timer - Display of time remaining before a measurement is taken. Ensures that all readings are taken at the appropriate reaction intervals for the test being performed.

Error messages - Messages on display alerting to problems including no cap, high zero, and standard to low.

Cooling lamp indicator - To maintain the desirable wavelength to be used for absorbance it is necessary to ensure component are not overheated from the heat generated by the tungsten lamp. Each photometer is designed to allow a minimal amount of time for components to cool. The cooling lamp indicator is displayed prior to a reading being taken.

Units of measure - Appropriate unit of measure is displayed along with reading.
