eSeasonGear SALT-3050 Waterproof IP65 Meter, Digital Salinity PPM Temperature Tester for Salt Water Pool and Koi Fish Pond
  • Precalibrated at 3000 ppm salt (NaCl) at 25°C / 77°F
  • Built-in ATC sensor for automatic temperature compensation; Built-in salt (NaCl) conversion factor for meter calibration
  • Salt Range: 0-5000 ppm or 0.0-0.5 %; Temperature Range: 0-55 °C or 32-130 °F; Waterproof Rating: IP65
  • Works ONLY for Salt Water Pool and Koi Fish Pond Salt level testing.
  • Will NOT work for Sea/Marine/Salt Water Fish Tank Salt level testing *** Will NOT work for Food salt level testing! *** Will NOT work for any other application!

If you own koi ponds and salty water, I would advise that you go for the eSeasonGear SALT-3050 Digital Salinity Pool Tester. This salinity tester s pre-calibrated at 3000PPM, meaning that you can use it immediately it arrives. Probably what made me include this among the best is because it can measure salinity levels between 0 to 5000PPM. As such, any water saltier than this range may not be suitable for this tester. 

I also liked the built-in Automatic Temperature Sensor that works exemplarily. The unit can measure water temperatures automatically without much calibration. The ATC sensor design is waterproof, holds measurements for some time if you want to note it down, and has a temperature range of 32 to 130°F. You can choose to do the readings in degrees Celsius or Fahrenheit according to your preference.

You will also like the auto power-off feature with disable functionality, adjustable automatic temperature compensation, and data hold functionalities. 

The TEKCOPLUS Pen Type Salinity and Temperature Tester also have some unique features, especially that it allows users to select between manual and automatic ranging capability when conducting tests. Like my first product, the eSeasonGear SALT-3050 tester, you can as well alternate between °F and °C measurement units. 

Key Features
  • Wide salinity range of 0 to 9999PPM 
  • Temperature range of -5 to 60°C

How Can I Test My Pool Water at Home?

It is recommended that you test pool water at least once every week to keep it safe and clean. Initially, I had no idea how I could measure the salt levels of my pool at my convenience. Well, all this changed when I discovered these handy digital pool testers. With the pool testing kit, all you need to do is to collect pool water samples in a bottle or cup. You should then dip the probe of the kit and note the readings on the instrument’s digital display screen. Based on the results, you can adjust the chemical composition of your pool to make it safe for swimming. 

How Accurate are Home Water Test Kits?

Digital saltwater pool testers are only accurate if calibrated correctly. This means that you find the best water test kits from reliable brands. Fortunately, most digital saltwater pool testers give precise arguably readings, especially for sodium chloride. However, since man-made equipment cannot be 100% accurate, I suggest that you allow a flexible accuracy rate of ±1%. 

The Bottom Line

Before selecting the best digital saltwater tester, it is good to have many options to compare and contrast the key features of individual testers. The review above outlines some intriguing features of the best pool water testers you should know before making a purchase decision. Investing in the right unit enables you to evaluate the salt level and maintain your pool correctly.
