Product Description: Digital TDS EC Temp Meter
The Digital TDS EC Temp Meter is a practical 3-in-1 water quality testing instrument designed to measure Total Dissolved Solids (TDS), Electrical Conductivity (EC), and temperature. It is suitable for checking filtered water quality, monitoring the performance of water filtration systems, and evaluating dissolved mineral content in water.
This TDS & EC Meter features a compact digital design with an easy-to-read display, Hold Function, Auto-off Function, and built-in digital thermometer. Its Automatic Temperature Compensation (ATC) helps provide convenient temperature-adjusted readings within the specified measurement range.
The meter is factory calibrated using a 342 ppm NaCl solution and can be recalibrated when required using a mini-screwdriver. It is supplied with a carrying case featuring a belt clip, making it convenient for laboratory, water treatment, household, and field testing applications.
