Description of πŸ§ͺ Hanna Instruments Salinity Tester HI98319: Accurate Salinity Measurement Made Easy

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.

Received a used item Best in Substance Analyzer

Do not recommend ordering this item. The goods came clearly used (see photo). This shows that someone tried to hack into the battery compartment and scratched the plastic case in two places. The teeth that work in the water are covered with some kind of black coating. The whole tester is scratched. Also, the instructions say to remove the plastic around the battery to allow it to turn on. there isn't even any plastic on it because the previous user took it off!

Pros
  • Excellent Overall Performance
Cons
  • Doubtful

Consistently low readings

Despite being calibrated with liquid food, the Hanna salt meter shows consistently low readings (1.023 when water is 1.026) compared to a calibrated refractometer. It was also tested with calibration fluid 1.026 from another company. This seems to be a known issue on online forums when properly calibrated and used correctly. On the other hand, while inaccuracy should be a hurdle, it's a comfortable and quick device to use, and if it's even consistently inaccurate, you can make up for it…

Pros
  • Slim design
Cons
  • Long delivery time

Inaccurate reading for testing, measuring and checking

I never normally give 1 star - usually I just don't check something I don't like because it's usually subjective. However, I feel this strongly enough to actually give it a bad rating. Out of the box I followed the instructions to calibrate using the included calibration liquid (35 ppt) but when I measured the salinity in my tank it showed 15 ppt below what I thought my tank was (my fish were still healthy). ). I calibrated it again with another bundled package and got the same results. I…
