Benchtop Multi-Parameter Meter NBMM-100

Benchtop Multi-Parameter Meter NBMM-100 is a laboratory apparatus designed for measurement of pH, conductivity, temperature, salinity, TDS etc of water and various industrial samples. It is equipped with built-in real-time clock that meets the GLP regulatory standards of any laboratory setting. It enables automatic temperature compensation for accurate display of reading value over the entire pH range and other parameters. The subsequent reminder alerts for calibration aids in maintaining the smooth functionality of a meter.
