Eliminate uncertainty in salinity measurements

Is your optical refractometer or hydrometer causing you to feel uncertain about your salinity measurements? The HI96822 Digital Refractometer eliminates this worry by digitally measuring your water's refractive index to determine the salinity of natural and artificial seawater – including brackish, ocean water or saltwater aquarium.

Features of the HI96822 Seawater Refractometer:

• Designed for seawater salinity analysis, not NaCl.
• Automatic temperature compensation from 0-80°C (32-176°F).
• High accuracy measurements displayed as PSU, ppt, and specific gravity.
• Comes with a two-year warranty.

The Razor X will meet the requirements of even the most sophisticated group of marine, reef and freshwater hobbyists.
410nm/420nm Super Actinic

The Razor X Lighting system utilizes the 410/420nm Super Actinic LED chips, the spectrum that's crucial for the success of any reef and water plant aquariums as it is required by Chlorophyll A for photosynthesis, where absorption peaks at 412nm.
Built-in Temperature Control System
The Razor X Lighting system deploys an ingenious aerodynamic design which draws cool air from underneath the fixture, through its body which also serves as a large heat sink, to dissipate heat passively. Equipped with fans to regulate fixture temperatures in enclosed environments. The fan(s) will be automatically engaged when the temperature is above 55°C/131°F, and disengage when it is below 45°C/113° F.
