Atago PAL-03CS Sodium Chloride (Brine Solution) Refractometer

The Atago PAL-03CS is a digital handheld refractometer designed to measure sodium chloride concentration and freezing point in brine and de-icing salt solutions with speed and precision. Winter road maintenance teams, municipalities, and highway operators use this instrument to optimize salt application rates and prevent excessive consumption.

The device delivers results in approximately 3 seconds using just 2-3 sample drops, measuring NaCl concentrations from 0.0-28.0% and freezing point values from 0 to -22°C with ±0.2% (g/100g) accuracy. Automatic temperature compensation across 10-40°C ensures reliable field performance under varying site conditions. IP65 water resistance rating makes it suitable for outdoor use and harsh winter environments. Weighing only 100 grams with compact dimensions (5.5×3.1×10.9 cm), it is easily portable and operates on 2×AAA batteries.

The PAL-03CS delivers faster and more consistent results compared to conventional methods, ensuring both adequate salt coverage for safety and preventing unnecessary over-application.
