เครื่องโฟโตมิเตอร์-คลอรีนอิสระ (Free Chlorine Photometer 0.00- 5.00 mg/L)

HI 96701

Free Chlorine Photometer with 525 nm filter and Cal Check

          Chlorine, the most ubiquitous disinfectant, is used in many treatment applications; from potable water, wastewater, to food industry and swimming pools. HI 96701 is an auto-diagnostic portable photometer for accurately measuring free chlorine. The advanced optical system employs a specialized tungsten lamp and a narrow band interference filter, assuring accurate readings between 0.00 to 5.00 mg/L. This instrument is equipped with Cal Check® validation function and standards to validate good performance at any time. Taking just a few short steps, the validation procedure is user-friendly and ensures that the meter is properly calibrated wherever you go. 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. Ideal for field applications, these meters are splash proof and the lamp and filter units are protected from dust or dirt by a transparent barrier. 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. Reagents are in powdered form and are supplied in packets. The amount of reagent is precisely dosed to ensure maximum repeatability. HI 96701 utilizes a method adaptation of USEPA Method 330.5 and Standard Method 4500-Cl G. Reaction between free chlorine and the DPD reagent causes a pink tint in the sample.
