Digital RS485 pH Sensor Electrode

Product Name:Digital RS485 pH Sensor Electrode 

Product modelCS1788D

Product brand:FLUIDINGS

Power supply voltage: 9~36VDC/RS485 MODBUS RTU

Purpose: Designed for pure water, low Ion concentration environment.Easy to connect to PLC, DCS, industrial control computers, general purpose controllers, paperless recording instruments or touch screens and other third party devices.

DESCRIPTION

Features

1.Using large-area low-resistance sensitive film bulb ≤30MΩ (at 25℃), suitable for usage in ultra-pure water

2.Using gel electrolyte and solid electrolyte salt bridge. Pool electrode is composed of two different colloidal electrolytes. This unique
technology ensures longer electrode life and reliable stability

3.It can be equipped with PT100, PT1000, 2.252K, 10K and other
thermistors for temperature compensation

4.It adopts advanced solid dielectric and large area PTFE liquid junction. It is not easy to be blocked and easy to maintain.

5.The long-distance reference diffusion path greatly prolongs the service life of the electrode in harsh environments.

6.The newly designed glass bulb increases the bulb area and prevents the generation of interfering bubbles in the internal buffer, making the measurement more reliable.

7.The electrode adopts high-quality low-noise cables, which can make the signal output length longer than 20 meters without interference. Pure water composite electrodes are widely used in circulating water, pure water, RO water and other occasions
