PHG-2091 online pH meter

PHG-2091 Environmental Protection Online PH Meter is an environmentally friendly online instrument developed and produced by Shanghai Botuo Instrument Co., Ltd. for testing pH value, with full functions Stable performance The characteristics of easy operation make it an instrument for testing and controlling pH in industrial enterprises.

The PHG-2091 series instrument can be equipped with various types of pH electrodes. PHG-2091 has antimony functionality and can be paired with metal antimony 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.
