Standard Seawater 35 ppt Refractometer Calibration Solution – 60 ml

Product details

Standard Seawater 35 ppt Refractometer Calibration Solution – 60 ml is a calibration liquid made for setting and verifying the accuracy of a refractometer used to measure salinity in marine (natural or synthetic) saltwater. In practice, it lets you calibrate your refractometer to a known reference point at 35 ppt before testing your aquarium water so your readings are more reliable.

Features:

• Specifically manufactured for calibrating refractometers intended for natural sea water or synthetic sea water testing
• Helps you confirm proper refractometer performance by calibrating to a known 35 ppt standard
• Recommended workflow includes cleaning the refractometer prism slide with clean fresh water, drying, and then applying calibration solution
• For ATC (automatic temperature compensating) refractometers, allow about 45–60 seconds after adding drops before reading
• After calibration, remove residue by cleaning the prism slide with clean fresh water and drying with a soft cloth before further use
• Designed to be used with your refractometer prior to each test for best results

Specifications:

• Calibration target: 35 ppt
• Solution volume: 60 ml
• Intended use: Calibrating refractometers for measuring salinity in natural sea water or synthetic sea water
• ATC read time (guidance): Allow 45–60 seconds after applying drops
