Description
Overview
GAOTek hydroponic dosing system ph tds ec meter water quality is developed on the basis of guaranteeing the performance and the functions. The clear display, simple operation and high measuring performance provide it with high-cost performance. It can be widely used for continuous monitoring of conductivity of water and solution in thermal power plants, chemical fertilizer, metallurgy, environmental protection, pharmacy, biochemical engineering, foodstuff, running water and many other industries.
Features
● The ECG-1903 series of microcomputer-based industrial control instruments are precision meters for measuring the conductivity or resistivity of solutions.
● With their complete functions, stable performance, simple operation, and other advantages, they are optimal instruments for industrial measurement and control.
● The advantages of this instrument include: an LCD display with backlight and display of errors.
● Automatic temperature compensation.
● Isolated 4–20 mA current output.
● Dual relay control.
● Adjustable delay.
● Alarming with upper and lower thresholds.
● Power-down memory; and over ten years of data storage without a backup battery.
● According to the range of resistivity of the water sample measured, the electrode with a constant k = 0.01, 0.1, 1.0, or 10 can be used by means of flow-through, immersed, flanged, or pipe-based installation.
