เครื่องโฟโตมิเตอร์-ฟอสเฟต (Phosphate Photometer 0.0-30.0 mg/L)
Phosphate, High Range Photometer with 525 nm filter and Cal Check
Phosphorous, present as phosphates in water and wastewater, comes from biological and industrial drains. Phosphates are present in agricultural fertilizers, in detergents and industrial process boilers to prevent corrosion. Phosphates are an essential nutrient for life but when present in excessive amounts leads to a process called eutrophication. Hanna offers a quick and affordable analysis for phosphates.
HI 96717 is an auto-diagnostic portable photometer for accurately measuring phosphorous. The advanced optical system employs a specialized tungsten lamp and a narrow band interference filter, assuring accurate readings between 0.00 to 30.00 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 96706 utilizes an amino acid method, adapted from Standard Method for the Examination of Water and Wastewater. The reaction between phosphorous and the reagents causes a blue tint in the sample.
