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.

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.
