Product Information

HI98319 is a digital salinity tester designed specifically for saltwater aquariums that displays 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.

• Waterproof and floats!
• Includes 4x of the Salinity Calibration Fluid Packets.
• Automatic Calibration – A 35.00 ppt solution is used for calibration and automatically recognized when in calibration mode.
• Displays results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.)
• Salinity readings are performed by an amperometric graphite probe that resists oxidation, providing better repeatability in measurements. The use of graphite also reduces the polarization effect common with testers that use two stainless steel pins.
• Accuracy @ 25 C/77 F is ±0.001 S.G.

• Displays results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.).
• Comes with all the necessary solutions and batteries- everything you need to get started measuring right away.
• Ideal for testing salinity in aquariums, field, and industrial settings.

Better Features for Better Testing

An onscreen stability indicator ensures the highest level of confidence in your results. The selectable auto-off feature prolongs battery life for peace-of-mind and energy savings if the meter is accidentally left on.

Pocket Sized

The compact size makes the HI98319 Marine Salinity Tester ideal for on-the-go testing. The multilevel LCD display provides at-a-glance salinity and temperature readings from any angle while dual button operation streamlines the testing process for any user.

Long Battery Life

The included CR2032 Li-ion battery provides up to 100 hours of continuous use. The battery icon will blink to let you know it is time to change the battery so you never miss a measurement.

Graphite Sensors

Unlike stainless steel sensors, graphite sensors reduces polarization effects and does not oxidize for more reliable and accurate readings.

Durable Casing

Designed to withstand the knocks, drops, and spills of real life, the waterproof body ensures top performance in any environment. These meters are totally protected against dust and water intrusion from any direction.

Integrated Temperature Probe

Conductivity measurements are very sensitive to temperature variations. HI98319 has an exposed temperature sensor to ensure fast, accurately compensated readings even during sudden temperature fluctuations.  We believe that buying a tester should be simple. Your HI98319 Marine Salinity Tester is equipped with everything you need for successful testing right out of the box.
