Digital Salt Water Pool Salt Tester with Long Probe 0-5000PPM.

Easy to Use Portable Pool Salt Tester: This salt tester has a long probe that allows you to use it without kneeling while testing the water. The maximum testing depth of this salt test kit is 13 inches, which can help you know the distribution of salt. The controls and instructions are simple and straightforward

LED Indicators Along the Probe: The probe also has LEDs along the length that show the approximate reading while the screen shows the exact amount of salt. It gives its reading within about 5 seconds and allows you to hold down the temperature button to continue reading once out of the water sample. It makes it very easy to see if your salt level is in range

Easier to use and faster to test the salinity of saltwater pools, spas, hot tubs and hot tubs: The salt meter uses a backlit digital LCD display design. To get an accurate reading, just look at the digital screen. Combine precise measurements with convenient visual cues. Readings are more accurate than complex test strips or test strips. Accurate readings even in dimly lit environments

Saltwater Salinity Tester: The testing range is 0-5000 PPM, so it is perfect for a saltwater pool (typically 2,700-3,400 PPM), a koi pond (100-500 PPM), a hot tub (1,500-2,000 PPM), or a freshwater aquarium (100-500 PPM). Temperature test range: 32-122℉/0-50℃. Please note, it is not suitable for testing saltwater or seawater aquariums

Digital Saltwater Salinity Test Kit: Comes with a 5000μS/cm calibration solution in case you need to recalibrate (it is factory calibrated when you receive it). It also includes some extra o-rings that go between the probe and the digital readout, but as long as you don't submerge it too deep, it shouldn't matter anyway
