Product Overview

Designed for aquarium enthusiasts, marine aquaculture and laboratory testing, this professional-grade seawater salinity refractometer is ideal for measuring salinity levels in seawater. Compared to traditional hydrometers, this optical refractometer provides more accurate and stable results. It features a dual-scale display for simultaneous reading of salinity in parts per thousand and specific gravity, and includes built-in automatic temperature compensation to ensure accurate readings at varying ambient temperatures. This essential tool helps to maintain a healthy environment for coral reefs and marine fish.

Key features:

• Dual-scale precise measurement:

The display window shows two reading standards simultaneously – specific gravity and salinity – catering to different user preferences without the need for conversion.

• ATC (Automatic Temperature Compensation): 

The instrument is equipped with advanced ATC technology and automatically adjusts for deviations within an ambient temperature range of 10°C to 30°C, eliminating concerns about temperature fluctuations affecting the accuracy of the measurements.

• High-definition optical prism: 

It utilises a high-quality optical glass prism with high light transmittance and a clear, sharp dividing line for easy, accurate readings.

The durable aluminium alloy body provides a solid feel and features a non-slip rubber handle for comfortable and stable operation.

• Easy operation: 

Simply add 2–3 drops of the liquid to be tested, observe it in the light and obtain accurate results in seconds.
