PHG-2091 typeonlinePH meter

PHG-2091onlineControl instruments are precision instruments used to test pH values, with full functionality Stable performance The characteristics of easy operation make itonlineThe ideal instrument for enterprise testing and control in the field of pH.

The PHG-2091 series instrument can be equipped with various types of pH electrodes.

Instrument features:

LCD (liquid crystal) display, using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, completes multi parameter measurement, temperature compensation, range conversion, high instrument accuracy, and good repeatability.

The current output and alarm relay adopt photoelectric coupling isolation technology, which has strong anti-interference performance and achieves remote transmission.

Alarm signal isolation output, alarm upper and lower limits can be set arbitrarily, alarm hysteresis cancellation.

Technical Indicators:
