Hanna photometers use the exclusive ready-made, NiST traceable standards to verify the performance of the instrument and recalibrate if necessary. Cuvets are constructed from specialized optical glass to ensure the best and most consistent results. The positive locking system ensures that the cuvet is in the same position every time it is placed into the measuring cell. Our sample cell is designed to fit a cuvet with a wide neck to make it easier to add both sample and reagents. All instruments are factory calibrated and the electronic and optical design minimizes the need for frequent calibration. Display messages aid the user during routine operation. The auto-off feature will disengage the meter after 10 minutes of non-use in measuring mode or 1 hour while in calibration mode. HI 96734 utilizes an adaptation of the USEPA Method 330.5 and Standard Method 4500-Cl. The reaction between free and total chlorine and DPD reagent causes a pink tint in the sample.

HI 96734 is supplied with (2) sample cuvets with caps, 9V battery and instruction manual.
