China Galvanic Corrosion Electrochemical Noise Measuring Meter Zra

CST500 Galvanic corrosion/ Electrochemical noise meter is composed of high-quality CMOS and BiFET® integrated circuits. It is used to monitor the real-time galvanic corrosion or electrochemical noise signals. The user can run the ENTools software (based on Windows OS) to control, or just press the touch keyboard on the panel to operate. The galvanic current density, galvanic corrosion rate, noise resistance Rn and pitting corrosion index can be obtained. ENTools software also supports vectorgraphs, and the graphs can be pasted into Word files.
CST500 employs the industrial-grade MCU control chip, and use chopper-stabilized amplifier Max7650 as the front end amplifier.Temperature drift is less than 1mV/ºC, and time drift is lower than 10μV/month. based on the principle of Zero Resistance ammeter, it monitors the electrochemical noise and galvanic current.
Main hardware features :
Built-in double channel 24bit high precision AD converter;
Maximum sampling rate is 1000Hz;
Auto current range;
Low-pass filter to elimilate the high-frequency noise inteference;
Communication: RS232/485;
All-optical isolation design circuits to avoid the influence of the ground circuit.

ENTools Software
ENTools software is for remote on-site galvanic corrosion measurement(see the below pic). It can be used to measure the galvanic corrosion and electrochemical noise signals, and calculate the galvanic corrosion rate through data analysis. The user can open multi data files simultaneously for editing and printing. It can graphically show real-time measured data . Data and graphs can be printed and saved easily.
