1 / 7JUMXSRLE Seawater Salinity Refractometer, Dual Scale with ATC
Dual: The JUMXSRLE seawater salinity refractometer offers specific-gravity and parts-per-thousand scales for checking saltwater samples. Its claimed automatic temperature compensation is specified for 10℃ to 30℃, so buyers should consider whether their testing conditions fall within that range.
At a glance
- Dual readings provide specific gravity and salinity in parts per thousand from one test, according to the listing.
- The listing claims automatic temperature compensation across its stated range and says no batteries are needed.
- A rubberized grip and compact form are claimed for carrying and handling.
Pros and cons
Pros
- Two measurement scales cover specific gravity and salinity, which can suit routine saltwater checks.
- The listed salinity range reaches 100‰, while the specific-gravity scale spans 1.000 to 1.070.
