SJG-3083 hydrochloric acid concentration meter Features:
All intelligent: SJG - 2083 Chinese online salt concentration meter with high precision AD conversion and single-chip microprocessor technology, can finish the HCL concentration measurement, temperature measurement, temperature automatic compensation, automatic conversion range, self-inspection of instrument, and other functions.
High reliability: components integrated into a circuit board, not the complex function switch, knob and potentiometer.
Anti-interference ability is strong, the output current photoelectric coupling isolation technique, strong anti-interference ability, realize remote transmission. Has the good electromagnetic compatibility.
Waterproof and dustproof design: the degree of protection IP65, suitable for outdoor use.
Automatic range switching: the electrodes covered by measuring range within the scope of automatic conversion.
RS485 communication interface, easy to get the computer monitoring and communications.
Phase sensitive detection: eliminate the influence of wire to salt concentration measurement.
Automatic conversion measuring frequency: avoid electrode polarization, improve the accuracy of measurement. Technical indicators:
