Profile:

The KDZL-807D is a precision surface/interfacial tension meter using the platinum ring method. It features a high-precision Wen’s bridge sine wave oscillator for stable, low-distortion measurement. Equipped with an improved closed magnetic force balance sensor, it offers fast response and linearity, requiring only one-point calibration. A built-in microprocessor provides bidirectional temperature compensation based on 25°C, adapting to all lab environments. It automatically calculates tension values, making it ideal for efficient liquid analysis.
