อุปกรณ์วัด Turbidity (measures turbidity and chlorine free / total)

HI 93414

measures turbidity and chlorine free / total
The HI 93414 turbidimeter using a tungsten light source meets the EPA (Environmental Protection Agency) and an advanced optical system, thanks to which we can make measurements of turbidity and chlorine free / total very accurate and reliable. The scale for the measurement of turbidity extends up to 1000 NTU, while the analysis of free or total chlorine may be carried out on a scale from 0.00 to 5.00 mg / l (ppm). Even the metering modes comply with the EPA rules: Depending on the measured sample and needed accuracy, users can opt for a normal measurement, continuous or for the AVG mode, which performs many reads and returns an average value.
This tool is equipped with the TIS – Tag Identification System, developed by HANNA, which allows users to record all measures indicating the date and place where they were made. The stored data can then be transferred to a PC via USB or RS 232.
The reliability of the instrument is guaranteed by the system Cal Check ® and the chlorine standard NIST ready to use. For turbidity calibration standards are available in two, three or four points, pre-defined or user-settable. Frequent calibration is not necessary as the system compensates for variations in the intensity of the light source.
feature GLP (Good Laboratory Practice) allows the traceability of calibration data, including date, time, and the last calibration points.
