GWQ-EC300 conductivity meter is an intelligent one-line chemical analysis equipment, widely used in continuous monitoring of temperature and conductivity value of the solution in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and running water and so on. The continuous monitoring data is realized by remote transmission monitoring and recording through the transmission output connection recorder. It can also be connected to the RS485 interface and can be easily connected to the computer for monitoring and recording through the MODBUS-RTU protocol.
