HANNA Marine Salinity Waterproof Tester – HI98319

The HANNA HI98319 Marine Salinity Waterproof Tester is a compact, waterproof, and easy-to-use salinity tester that is ideal for saltwater aquariums.
The tester uses conductivity to determine the salinity of natural and artificial seawater, and it can display results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.).
This waterproof tester uses an amperometric conductivity probe to determine the salt content in the water.

The HI98319 comes with everything you need to get started testing right away, including a protective cap, 35.00 ppt calibration solution sachets, a CR2032 battery, a plastic storage case, an instrument quality certificate, and an instructional manual.

Features:

• Compact, waterproof and designed to float
• Easy to use
• Measures salinity in ppt, PSU, or S.G.
• Measures salinity up to 70.00ppt
• Automatic Temperature Compensation (ATC), displays temperature in °C or °F
• Comes with everything you need to get started
• Accurate and reliable
• Exposed Temperature Probe for Fast Response

Benefits:

• Ensures the proper salinity level in your saltwater aquarium
• Helps to prevent algae blooms and other problems
• Simple to use, even for beginners

:

• Salinity measurements calculated from a conductivity measurement using known tables
• Choice of measurement units displayed in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.)
• Amperometric graphite sensor reduces polarization effects and does not oxidize
• Large LCD displays stability indicator, low-battery indicator, and calibration tags
• Dedicated calibration button with automatic recognition of the 35.00ppt calibration solution in calibration mode
• Supplied complete with meter and calibration sachets in a durable plastic storage case.
