HANNA HI93703 [HI731313] Portable Turbidity Meter Maintenance Kit

The HI93703 turbidity meter is a portable, microprocessor-based instrument used to determine the turbidity of water and wastewater with high precision in the $eld as well as in the laboratory.
The HI93703 covers a 0 to 1000 FTU range in two scales: 0.00 to 50.00 FTU and 50 to 1000 FTU. The auto-ranging feature sets the appropriate range for the measurement.

The HI93703 has been designed according to the ISO7027 International Standard, consequently the turbidity unit is the FTU (Formazine Turbidity Unit). FTU is equivalent to the other internationally recognized unit: NTU (Nephelometric Turbidity Unit).

The meter is very simple to use: all operations can be carried out with only four keys and troubleshooting functions can be performed with displayed error code guides.
The one-point calibration at 10 FTU* can be easily performed using the available standard.

Hanna has chosen 10 FTU * as the calibration point because it is the value that best $ts the water turbidity measurements in di&erent applications, from drinking water to wastewater treatment.

HANNA instruments uses the primary standard AMCO-AEPA-1 to avoid all formazine-related problems. Formazine is a very toxic, unstable substance, which requires particular care: its standards have to be prepared only a few minutes before performing the calibration, and can-not be reused because of their short life.
Hanna Instruments standards are extremely stable, can be reused, and last up to six months if free from contamination.

The HI93703 can be used with both standards.
