Description
CD-5000 Tap water conductivity TDS instrument
Online electrical conductivity meter CD-5000 Tap water conductivity TDS instrument
Online electrical conductivity meter CD-5000 is an online intelligent Resistivity/EC/TDS meter independently developed by our company. Using high-performance CPU chip and SMT chip technology to complete Resistivity/EC/TDS and temperature measurement, temperature compensation, automatic range conversion, high precision, good repeatability. It is widely used in continuous monitoring of Resistivity/EC/TDS value in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water.

Main features
★ Waterproof, dust proof, moisture-proof (IP65), high-end design look.
★ High precision, high stability and preferable antijamming ability.
★ Large screen LCD display, multi-parameters display simultaneously.
★ It can measure the Resistivity/EC/TDS, control the upper and lower limits, and automatically switch the range to improve the measurement resolution of the product.
★ The screen displays the alarm status and can be accompanied by the switch ON/OFF signal output.
★ Automatic temperature compensation function: 0～100℃.
★ Communicate function：Both the RS485 and 4-20mA interfaces use opto-isolation technology. The RS-485 communication interface is compatible with the MODBUS part protocol part (optional), and can convert RS-232. The Resistivity/EC/TDS value corresponding to the 4~20 mA current output can be arbitrarily set. And it also support to connect loT of company and customize loT for customer.
★ The hysteresis amount can be set arbitrarily to avoid frequent switching of the switching relay.
★ Watchdog function: make sure the meter doesn't crash.
★ Recoverable factory setting.
★ Power off protects > 10 years.
