6031 Salt Tester - Gondo

The salt level is the fundamental parameter of salt treatment. If the concentration is too low, the chlorinator does not produce enough chlorine and the water is not properly disinfected. If it is too high, it can damage the electrolysis cell and corrode metal equipment. Most salt chlorinators operate between 3,000 and 6,000 ppm depending on the manufacturer. Regular checks with the 6031 tester allow you to precisely adjust the amount of salt to add and extend the life of your installation.

TDS (Total Dissolved Solids) measures the total concentration of all dissolved substances in water in ppm (parts per million), including salt, minerals, treatment chemicals, and organic residues. The salt level is a component of TDS, but not its only constituent. The 6031 tester measures TDS over a range of 0 to 19,990 ppm and converts this value to give you a reliable estimate of your pool's salt level, taking into account other dissolved solids present.

The 6031 tester covers a TDS measurement range of 0 to 19,990 ppm, with a resolution of 10 ppm. This range is perfectly suited for pools with salt chlorinators whose salt level is generally between 3,000 and 6,000 ppm. The 10 ppm resolution guarantees a sufficiently precise reading to correctly dose your salt additions and maintain your chlorinator in its optimal operating conditions.

Water conductivity — which is the basis for TDS measurement — naturally varies with temperature: warmer water conducts electricity better and would skew the reading upward without correction. The 6031 tester's ATC (Automatic Temperature Compensation) function automatically detects the water temperature and corrects the measurement in real-time to guarantee an accurate result, whether the water is cold at the start of the season or heated in summer. This is an essential feature for reliable measurements throughout the season.

Yes, the 6031 tester is certified IP57, which means it is protected against temporary immersion up to 1 meter deep for 30 minutes. Its shock-resistant ABS casing withstands drops and demanding use conditions around a pool. These two combined protections make it a durable tool, designed for daily outdoor use, even in case of accidental contact with water or a drop on pool decking.

Checking the salt level is recommended at the beginning of the season to adjust the concentration after wintering, then approximately once a month during the season. An additional check is necessary after heavy rain (water dilution), partial draining, or any significant water top-up. If your chlorinator displays a low salt alarm or its chlorine production seems insufficient despite correct settings, an immediate measurement will help verify if the salt level is the cause.

Turn on the tester and immerse the electrode in your pool water to a depth of about 5 to 10 cm, away from return jets and chemical injection areas. Gently swirl the device to remove air bubbles. Wait for the value displayed on the LCD screen to stabilize, which usually takes a few seconds thanks to the sensor's quick response. Rinse the electrode with clear water after each use and dry it before storing the tester.

Yes, the 6031 tester is a universal measuring tool that works with all salt chlorinators, regardless of brand (CCEI, Hayward, AstralPool, Pentair, Aquagem, etc.). You just need to know the salt range recommended by your chlorinator (indicated in its manual, generally between 3,000 and 6,000 ppm) and compare the value measured by the 6031 to determine if salt needs to be added. It is also an excellent independent verification tool when your chlorinator's display seems inconsistent.

These two Gondo testers are complementary but measure different parameters. The 6011 tester measures the water's pH (its acidity or basicity, between 0 and 14) with an accuracy of ±0.1 pH. The 6031 tester measures the water's salt/TDS concentration in ppm, essential for the proper functioning of a salt chlorinator. For comprehensive water management of a pool with a salt chlorinator, both testers are recommended: pH directly influences the efficiency of the chlorine produced by the chlorinator.

After each use, rinse the electrode with clear water to remove salt and chlorine residues that could affect the accuracy of subsequent measurements. Dry the device before storing it. Always turn off the tester after use to preserve the life of the CR2032 batteries. At the end of the season, store the tester away from frost and chemicals. If the measurements seem unstable or inconsistent, start by checking the battery status before suspecting a sensor malfunction.
