The Hanna Instruments Marine Salinity and Temperature Tester (HI98319) was designed to simplify testing your salt mix`s salinity and temperature in seconds, with reading results in parts per thousand (ppt), Practical Salinity Units (PSU), or specific gravity (S.G.).

This waterproof tester uses a graphite amperometric conductivity probe, which is resistant to oxidation, improving the measurement repetition to determine the salt content in the water. The use of a graphite probe also reduces the polarization effect common with testers that use two stainless steel pins.

Calibration is performed by pressing the dedicated calibration button. Once in calibration mode, the probe is placed in 35.00 ppt calibration standard. When the standard value is recognized and stability reached, the meter will automatically accept and store the value. 

The Hanna Marine Salinity Tester displays the readings along with temperature on an easy to read large LCD screen. 

Better Features for Better Testing

  • With an onscreen stability indicator you can be confident in the reading results.  
  • The included auto-off feature will save energy, lengthening your battery life.

Pocket Sized

  • Perfect size for on-the-go testing.
  • With large LCD screen, you will be able to view the readings at a glance from any angle.

Long Battery Life

  • The CR2032 Li-ion battery will provide up to 100 hours of use.
  • The battery icon will blink when it is time to change the battery.

Graphite Sensors

  • Graphite sensors reduces polarization effects and does not oxidize, giving you a more reliable and accurate reading.

Durable Case

  • The design of this tester can withstand drops, knocks, and spills.
  • The waterproof body will protect the tester from any intrusion

Integrated Temperature Probe

  • Conductivity measurements are highly sensitive to temperature variations, which the exposed temperature sensor helps compensate for.
  • The temperature probe takes these variations into consideration to ensure accuracy.

I’ve been using this about a week and it’s awesome! Easy to calibrate, quick and easy to use. Compared to my Vertex refractometer it’s dead on - just way quicker and easier to use.

PROS
Quick and easy. Rapid results.
CONS
Price in comparison to an ordinary refractometer. Would have been nice if it had an LED light to illumminate numbers.
REVIEW
So far so good! Just got the tester today. Calibration was easy. I did you-tube a video to aid me in setting up tester. Directions are easy to read. I just wanted to make sure I did it correctly Salinity tester was accurate in comparison to my old refractometer.
It seems worth the money....Read More
