Our Products
Our product range contains a wide range of Digital Refractometer for Seawater Analysis and Digital Refractometer
The Digital Refractometer for Seawater Analysis is a rugged and portable digital refractometer designed specifically for measuring the salinity of natural or artificial seawater. It measures the refractive index of a small sample (as little as 100 µl) and automatically converts the reading into one of three commonly used salinity units: PSU, ppt or specific gravity (20/20). .tw
Rapid response: Measurements displayed in 1.5 seconds.
Automatic Temperature Compensation: Ensures accuracy over a range of sample temperatures.
IP65 water-resistant rugged design – Suitable for fieldwork near marine or corrosive environments.
Built with a stainless-steel sample well and high-grade flint glass prism: robust optics, easy to clean.
Battery powered (9 V), portable, with auto-off feature after 3 minutes of inactivity to preserve battery.
Dual-level LCD: Simultaneous display of measurement and temperature for convenience.
One-point calibration using distilled or deionized water: quick and simple to maintain.
High accuracy: ±2 PSU (or equivalent) and ±0.002 SG which is good for professional use.
Salinity monitoring in aquaculture and marine farms (seawater, brackish) where accurate salinity is critical for organism health.
Environmental monitoring of seawater or brackish water bodies, estuaries, desalination feed water, where salinity must be tracked.
Laboratory and field work in marine science, oceanography or coastal research requiring quick portable salinity measurements.
Marine engineering, ballast water monitoring, ship/boat systems where salinity or specific gravity of seawater is relevant.
Hobbyist or professional aquarium/fish-keeping applications, especially marine saltwater systems where precise salinity is needed.
Desalination plants or water treatment facilities where seawater or brackish feed water needs monitoring for salinity control.
TheDigital Refractometer is a precision instrument designed to measure the Brix value of liquids quickly and accurately. It provides measurements in 085% Brix with an accuracy of 0.2%, and features automatic temperature compensation between 1040C (50104F). Its compact design, SS ring and flint glass prism, and fast measurement time of approximately 1.5 seconds make it ideal for laboratory, industrial, and food/beverage applications.
