NMD-99 intelligent acid concentration meter
I Introduction
NMD -99S Intelligent inductive Acid concentration meter is designed according to the principle of electromagnetic induction of a new continuous online monitoring instrumentation, sensing element have no contact with the measured medium , the non-polar effect , resulting in a continuous measure, and has the general electrode instrument unparalleled advantages.
II Application
Power generation, printing and dyeing industry, metallurgy and environmental protection industries acid concentration measurements.
Concentration measurement conditions: the measured medium is a single -component system ( or contain other medium , weak medium)
III Feature
1.Electromagnetic detecting element doesn’t contact with the measured medium directly. There is no electrode polarization effect.
2.Large-screen LCD, english menu guide operation,easy to learn
3.Built in concentration curve of common acid salt, by setting the call the curve read concentration values, users can also create a desired concentration curve.
4.Multi-point calibration ensures the measurement accuracy in a wide range.
5.The probe is anti-corrosion which can measure various corrosive acid, alkali, salt solutions.
6.It can store and query historical data and trend curve.
7.The Modbus RTU protocol RS485 communication interface and 4-20mA analog signal output can be optional.
8.Two-way alarm relay (conductivity) output is optional.
