pHG-3081 industrial pH meter

pHG-3081 industrial pH meter

●Overview

   The pHG-3081 industrial pH meter is the latest generation of Chinese (English) microcomputer high-end instrument of RAMZY company. It has Chinese (English) display, Chinese (English) menu operation, full intelligence, multi-function, high measurement performance, Features such as strong environmental adaptability. This watch is a highly intelligent online continuous monitor, composed of two parts: a sensor a secondary watch. Can be equipped with three compound two compound electrodes to meet various places of use. It can be widely used in the continuous monitoring of pH value in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food tap water.

●Features

The new layout design, cast aluminum shell, metal texture, to create a high-grade E era water meter!

Simple menu structure, text-based dialogue between people tables: Compared with traditional instruments, the function of DOG-682 has been increased a lot, but due to the use of a separate menu structure, similar to the computer operation method, it is clearer more convenient to use. There is no need to memorize the operation steps operation sequence; you can operate according to the prompts on the screen without manual.

Intelligent: Using high-precision AD conversion single-chip micro-processing technology, it can complete various functions such as pH value temperature measurement, automatic temperature compensation, instrument self-test.

Reliability: The components are integrated on a circuit board without complex function switches, adjustment knobs potentiometers.

Double high-impedance input: Using the latest devices, the double high-impedance input impedance is up to 1012Ω, the anti-interference ability is strong;

Solution ground: Eliminate the interference of the ground loop.

Current isolation output: adopt photoelectric coupling isolation technology, strong anti-interference ability, can be transmitted remotely;

Communication interface: It can be easily connected to a computer for monitoring communication.

Automatic temperature compensation: Automatic temperature compensation at 0～99.9℃.

Waterproof dustproof design: Protection class Ip54, suitable for outdoor use.

               Adopt menu structure, similar to microcomputer operation, simple operation, full Chinese prompts for operation steps, without manual, you can easily complete.

Multi-parameter display on the same screen: display pH value, input mV number ( output current), temperature, time status on the same screen.
