DOG-2092A industrial dissolved oxygen meter

●Overview

DOG-2092A industrial dissolved oxygen meter is a highly intelligent online continuous monitor produced by RAMZY. The DOG-69F (ppm level) on-line dissolved oxygen electrode is characterized by fast response, stability, reliability, low cost of use. It is suitable for customers to use in large quantities.

●Features

● Microcomputer: High-performance CPU chip, high-precision AD conversion technology SMT patch technology are used to complete multi-parameter measurement, temperature compensation, automatic range conversion, high accuracy good repeatability

● Reliability: touch buttons, no switch travel button potentiometer

● Alarm function: The alarm signal is isolated output, the upper lower alarm limits can be set arbitrarily, the alarm lag is cancelled

● Isolation current output: The upper lower limits of the current output corresponding to the dissolved oxygen value can be set arbitrarily
