The KDZL-203 is a high-precision automatic surface and interfacial tension meter designed for accurate liquid testing. It employs a fast-response electromagnetic force balance sensor to enhance measurement accuracy and linearity, with a single-point calibration that eliminates the need for multi-point calibration and manual zero adjustment. The instrument features real-time display of equivalent tension and current weight, plus integrated temperature detection for automatic temperature compensation. A 240×128 dot-matrix LCD with unmarked keys and screen protection ensures intuitive operation, while time-stamped historical records (up to 255 data points) and a built-in high-speed thermal printer support efficient data management and output.
