B Type Turbidimeter, Measurement Range 0 ~ 10, 0 ~ 100, 0 ~ 1000, 0 ~ 4000NYU (CAT#: STEM-AE-0027-LGH)

Portable, AC and DC power supply, with low voltage indication and automatic shutdown function. The serial RS232 communication interface can be connected with a micro printer.
Microcomputer low-power configuration, touch keyboard, LCD screen with backlight, can display date, time, measurement value and measurement unit at the same time.
The measurement range can be manually selected or automatically switched. The calibration standard value can be set arbitrarily by programming, and 1-7 points can be quickly and arbitrarily selected for automatic calibration.
Equipped with average measurement mode and data query mode, with non-linear processing and smoothing functions of measurement data, with self-diagnosis information prompt.
Built-in clock memory storage system, real-time storage of measurement and correction data, long-term storage and recall of the latest 20 sets of measurement data.
A variety of measurement modes, preset with NTU, FTU, EBC, degrees (Unit), ppm, mg/L, % and other units.
Equipped with a chromaticity compensation system, which can effectively avoid the interference caused by the color of the sample, and can correctly reflect the concept of turbidity.
100,003 hours long-life high-intensity light source, maintenance-free long-term use, in line with ISO turbidity measurement standards.
