Its platinum-black sensor minimizes electrode polarization at high salt concentrations, while automatic temperature compensation maintains measurement accuracy across varying solution temperatures. Its single-button operation makes it suitable for quick brine and saline-water testing without sample preparation.\u003c\/p\u003e\n\n\n\u003cp\u003e• Brand: Apera Instruments\u003cbr\u003e\n• Model \/ SKU: 5053 \/ AI237\u003cbr\u003e\n• Measurement Parameter: NaCl concentration (% w\/w)\u003cbr\u003e\n• Measurement Range: 0–20% NaCl\u003cbr\u003e\n• Accuracy: ±0.4%\u003cbr\u003e\n• Sensor: Platinum-black electrode\u003cbr\u003e\n• Temperature Compensation: Automatic (ATC), 0–60°C\u003cbr\u003e\n• Calibration: Automatic one-point calibration; approximately monthly under normal use\u003cbr\u003e\n• Operation: Single-button dip-and-read with automatic shutoff\u003cbr\u003e\n• Dimensions: 176 × 39 × 25 mm\u003cbr\u003e\n• Important Limitation: Does not measure EC, TDS, ppm, or seawater salinity in ppt.\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: Its platinum-black sensor provides reliable NaCl concentration measurements up to 20% in a compact, easy-to-use instrument.
