Online electrical conductivity meter EC/TDS meter CD-5000

Product

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.
★  Automatic temperature compensation : 0～100℃.
★  Temperature compensation：NTC10k, The temperature compensation coefficient can be corrected based on 25℃.
★  Control interface: Two group of ON/OFF relay control interface（Passive port）, Divided into Resistivity/EC/TDS, temperature control signal photoelectric isolation output .
★  4-20mA output: one current output, photoelectric isolation protection, improve anti-interference capability.
★  485 interface: optically isolated output, support for IOT, (partially compatible with MODBUS protocol)².
★  Relay: The relay hysteresis is arbitrarily set, relay load 3A 220VAC².
★  Working conditions: Ambient temperature is 0~60°C, relative humidity ≤90%.
★  Output load: <750Ω（4-20mA）.
★  Working voltage: 220VAC ±10%, 50/60HZ.
★  Size: 100*106×168mm.
