Product Introduction

Mist/turbidity meter NDH 2000Ncharacteristic

NDH 2000 complies with the following three standards: (JIS K 7361, ISO 13468) (JIS K 7136 [2000], ISO 14782 [1999]) (JIS K 7105, ASTM D 1003). A 150mm diameter integrating sphere is used to place transparent plastic samples to compensate for aperture errors in the integrator.

1. 2. Fast measurement, high-precision automatic sample testing, easy operation, press the START button, no need to move the sample. (Compensation method provides compensation for gaps and changes in optical path)

1.3. Standard lighting D65 and A can be selected through a switch (optional)

1. 4. The precise haze (turbidity) measurement unit provides additional functions beyond basic haze (turbidity) measurement

1.5. Each unit is displayed in interactive mode (dialogue), so it can be easily operated even if it has not been operated before

1. 6. The optical system is beneficial for improving accuracy and interactive testing of total and diffuse light transmittance coefficients

1. 7. A stable power supply greatly improves measurement stability and reproducibility

1.8. High speed 16 bit A/D converter (with built-in 18 bit automatic correction function), low drift, high-speed, high-precision amplifier, enabling measurement accuracy to reach 0.002% (100 full scale). It is precisely because the instrument has such a device that it can accurately measure both high and low turbidity samples.

1.9. The large screen fluorescent tube display allows you to clearly see the content on the screen from any angle in front of it.

1. 10. The measurement results can be printed and output through a built-in thermal printer, which can also be felt in a quiet environment with low noise. The instrument is required to not work continuously for 24 hours.

1. 11. The sample name input function allows the sample name and result to be output simultaneously (via RS-232C). This function is very useful when the measurement results are controlled by a computer.

1. 12. Built in clock function, allowing external output (RS-232C) or printing output together with test results (YY/MM/DD/HH/MM).

1. 13. The testing unit has a data backup function to prevent the loss of measurement conditions, such as optical conditions and data. This function is quite useful, as once the conditions are set and saved, they will not be lost even if the power is disconnected.
