4 functions digital multimeter pH, EC, TDS, Temp

4-function digital multimeter pH, EC, TDS, Temp from the brand Loqman Optimum Research, is an accurate and practical device for simultaneous measurement of four vital parameters of water and solutions. This device is equipped with an auto-calibration system and provides an accuracy of one hundredth (0.01) in measuring pH (acidity), EC (electrical conductivity), TDS (total dissolved solids) and temperature. The rugged design, large, legible display, and simple operation make it ideal for use in laboratories, modern agriculture, hydroponics, water treatment, food processing, and quality control. Autocalibration reduces user error and increases the stability of results, while 100% accuracy ensures professional analysis.
