เครื่องโฟโตมิเตอร์-ซิลิกา (Silica High Range ISM Photometer 0- 200 mg/L)
Silica High Range ISM
The HI 96770 is an auto diagnostic portable microprocessor meter that benefits from HANNA’s years of experience as a manufacturer of analytical instruments. It has the advanced optical system based on a Light Emitting Diode (LED) and a narrow band interference filter that allows most accurate and repeatable readings. All instruments are factory calibrated and the electronic and optical design minimizes the need of frequent calibration.
With the powerful CAL CHECK™ validation function, you are able to validate good performance of your instrument at any time. The validation procedure is extremely user friendly. Just use the exclusive HANNA ready-made, NIST traceable standards to verify the performance of the instrument and recalibrate if necessary.
The instrument is splash waterproof and the LED and filter units are protected from dust or dirt by a transparent cup. This makes the instruments fulfill field applications. Display messages aid the user in routine operation. The meter has an auto-shut off feature that will turn off the instrument after 10 minutes of non use in measurement mode or after 1 hour if left in calibration mode.
The meter uses an exclusive positive-locking system to ensure that the cuvet is in the same position every time it is placed into the measurement cell. It is designed to fit a cuvet with a larger neck making it easier to add both sample and reagents. The cuvet is made from special optical glass to obtain best results.
The HI 96770 meter measures the molybdate reactive silica (SiO2) content in water samples in the 0 to 200 mg/L (ppm) range. The method is an adaptation of the USEPA METHOD 370.1 for drinking, surface and saline waters, domestic and industrial wastes and Standard Method 4500-SiO2 C.
The reagents are in powder form and are supplied in packets. The amount of reagent is precisely dosed to ensure the maximum repeatability.
