These portable instruments are dedicated to a specific ion and unlike conventional spectrophotometers and Ion Selective Electrodes, are fast and simple to use.

Hanna's portable photometers feature an advanced optical system; the combination of a light emitting diode (LED), a narrow band interference filter, and silicon photodetector ensure accurate photometric readings every time. The Hanna exclusive CAL Check^™ feature utilizes ready-made standards traceable to a NIST Standard for performance verification 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.

The readings are shown in large digits on a clear LCD, no need to worry about matching up colors or guessing where one color zone starts and the other finishes. Supplied with sample cuvettes (2) with caps, 9V battery, instrument quality certificate and instruction manual. Warranty: 2 years.
