เครื่องโฟโตมิเตอร์-เหล็ก (Iron Photometer 0.00- 5.00 mg/L)
Iron, High Range Photometer with 525 nm filter and Cal Check
Low concentrations of iron are naturally present in water, but iron levels rise in wastewater effluents. Iron is an indicator of corrosion and its concentrations in boilers and cooling towers must be monitored. To check for the presence of iron, HANNA® has designed HI 96721 to use powdered reagents, pre-dosed in the proper quantity to provide maximum reproducibility. Analysis is very simple, and is performed with just one sachet to measure soluble and easily reduced forms of iron. HI 96721 is an auto-diagnostic portable photometer for accurately measuring iron. 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. adaptation of the USEPA Method 315B and Standard Method 3500-Fe B. The reaction between Fe+2 and the phenanthroline reagent causes an orange tint in the sample.
