Hanna Waterproof Salinity tester
Designed to bring simplicity to salinity testing during the any process, the HI98319 Marine Salinity Tester measures conductivity (EC) to determine the salinity of natural and artificial seawater. Within seconds, the salinity and temperature are digitally displayed on the LCD.
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.
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.
4 x 35.00 ppt Calibration Standard Sachet Solution 
When performing a calibration it is important that the correct buffers are used. We include some starter buffer to get you going. The single-use sachets are individually sealed so you use fresh buffer each time you calibrate.
Protective Case 
Your tester comes with a complimentary carrying case to keep your tester safe from potential drops or bumps when not in use.
