Portable turbidity meter

Hanna microprocessor-based portable turbidity meters provide laboratory-grade accuracy for field or laboratory use. HI93703-11 measures turbidity from 0 to 1000 FTU (NTU). For best accuracy, HI93703-11 measures from 0.00 to 50.00 FTU in steps of 1/100th of FTU. The meter meets ISO 7027 requirements. HI93703-11 is equipped with an infrared LED light source. The infrared LED has a long life and maintains constant emission for the life of the instrument. The wavelength peaks at 890 nm, which provides the required intensity of diffused light even in samples with low turbidity values, and also reduces the interference from colours.

Good laboratory practice (GLP) circuitry automatically stores and retrieves the last calibration date and data, which can be displayed at the touch of a button. The meter has 3-point calibration, a real-time clock and internal logging for up to 200 measurements. Collected data can be downloaded to management systems using optional Windows-compatible HI92000 software.

The meter is supplied complete with measurement cuvette and cap, RS232, 4 x 1.5 V AA batteries and instruction manual in a hard carry case.
