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.
