Description
The Kalstein Salinity Refractometers YR05887 // YR05914 are precision instruments designed for measuring the concentration of salt in water, whether it’s for research, clinical laboratories, or the marine industry. Ideal for marine saltwater tanks, these refractometers feature a dual scale that provides a direct reading of both specific gravity (ranging from 1.000 to 1.070) and concentration in parts per thousand (up to 100 ppt). Equipped with Automatic Temperature Compensation (ATC), they deliver accurate readings regardless of temperature fluctuations. Built with high-quality materials, they’re durable and require no batteries, ensuring long-lasting performance with only ambient light.
Market Price
While the price for the average salinity refractometer can vary significantly, the market for high-quality instruments like the Kalstein Salinity Refractometers typically ranges from $70 to $210. These devices represent a sound investment for professionals seeking reliable and precise salinity measurements.
Frequently Asked Questions
Q: Does the refractometer need a power source?
A: No, it uses ambient light, making batteries or an external power source unnecessary.
Q: How do I calibrate it?
A: Calibration is straightforward and can be done with distilled water and a small screwdriver.
Q: How durable is the product?
A: Constructed with high-quality pure aluminum, it is designed for long-term use.
Advantages and Disadvantages
Advantages: Simple to use, no power source needed, ATC function for accurate readings, high build quality.
Disadvantages: Limited to saltwater applications, must be handled carefully to maintain accuracy.
