Product Introduction
I. WQ-COND Conductivity Sensor Product Overview:
WQ-Cond Conductivity SensorUses 4-electrode measurement technology to provide accurate readings of conductivity and temperature over a wide range. Since the conductivity of ionic solutions increases with temperature, a built-in temperature sensor provides automatic temperature compensation of 2%/ºC relative to the standard 25ºC. The built-in interface module converts digital conductivity and temperature data into two independent 4-20mA signals, which can be connected to data loggers and programmable logic controller (PLC) devices respectively.
