TDS-10 Pen-Type TDS Meter, 0-9999 ppm (CAT#: STEM-BC-4000-ZJF)

The TDS-10 is a handheld pen-type instrument for measuring total dissolved solids in water. It estimates TDS from the electrical conductivity of the tested solution. The wide measurement range supports applications in chemical, water-treatment, pharmaceutical, electronic, beverage, and research environments. The LCD clearly displays both TDS and temperature values. Automatic temperature compensation helps maintain consistent readings across different sample temperatures. The data-hold function allows users to freeze a result for observation or documentation. Temperature units can be converted directly through the instrument controls. A replaceable platinum-black electrode provides efficient conductivity sensing and convenient maintenance. The waterproof housing includes buoyancy protection and long-life sealed buttons for reliable field operation.
