Advanced Measurement AccuracyAchieve highly reliable salinity readings with a refractometer accuracy of 1 ppt. Its optical prism and manual calibration ensure each measurement is precise, making it suitable for both professional and hobbyist use.
User-Friendly and Portable DesignWith its lightweight (approx. 200 grams) and compact dimensions (195 mm x 40 mm x 40 mm), this refractometer is both portable and easy to use on the go. The included carrying case and cleaning cloth allow for safe transport and effortless maintenance.
Dual Scale & Automatic Temperature CompensationEffortlessly switch between parts per thousand (ppt) and specific gravity for versatile applications. The built-in Automatic Temperature Compensation (ATC) ensures accurate readings within a temperature range of 10C to 30C, adapting to environmental changes.
FAQs of Salinity Refractometers:
Q: How does the salinity refractometer with eyepiece focus adjustment operate?
A: This handheld refractometer requires manual reading and adjustment. You simply place a drop of your saltwater sample on the optical glass prism, look through the eyepiece (which can be focused for clarity), and read the salinity value directly on the dual scale display.
Q: What types of environments or applications is this refractometer suitable for?
A: It is designed for a wide range of uses, including aquariums, laboratories, and field studies. Its durable aluminum construction and portable carrying case make it suitable for both indoor and outdoor environments.
Q: When should I calibrate the refractometer, and how is it done?
A: Calibration should be performed regularly and whenever you observe inconsistent readings. Use the calibration adjustment screw and a calibration solution (usually distilled water or a known standard) to ensure accurate measurements.
Q: Where can I benefit most from using this optical refractometer?
A: You will find it most beneficial where precise and quick salinity readings are required, such as in marine aquariums, water quality testing labs, and during field research in marine biology or aquaculture.
Q: What is the process for cleaning and storing the refractometer?
A: After each use, clean the optical prism with the included cleaning cloth and store the instrument in its carrying case. Always keep the rubber protective cap on the lens to avoid scratches and dust accumulation.
Q: How does Automatic Temperature Compensation (ATC) enhance measurement accuracy?
A: ATC automatically adjusts readings to compensate for temperature fluctuations within 10C to 30C. This ensures consistent and accurate results, regardless of minor ambient temperature changes during use.
