Why limit yourself to just one digital test, when you can have FIVE? This multi-function all in one PoolMeter digitally checks your pool salt level instantly. No more waiting for results to ensure your pool has everything it needs to stay clean and balanced. Recommended salt levels are 2700-3400 ppm.

Braxlee Pool Meter also comes with the advanced feature to check your pool and spa PH levels. Pools and Spas should be between 7.2-7.8.

The 5 in 1 PoolMeter tests for Salinity, PH, TDS, EC, and Temperature and can also be used for many other applications including: measuring content of edible salt, seawater, koi fish pond, marine waters, and aquarium tank testing.

【Wonderful Helper for Pool Salinity Measurement】This salinity meter is perfect for testing the salinity of swimming pools. It helps you to detect the salt level in your salt system. Scale range: 0~9999 ppm/10.0~200 ppt and 0.00-25.00%. Please note: Please remove the two silicone protective caps from the platinum electrodes before use, otherwise it cannot be used properly.

【Detects Free Chlorine Levels】The ORP value is a measure of the oxidative power or sterilization strength in water pool salt. The higher the ORP value in water, the stronger the oxidative power and sterilization ability. The ORP's can reflect the residual chlorine (FAC) levels in the Saltwater pool.

【Highly Sensitive PH Probe】A low pH means the water is acidic, which can be corrosive to pool equipment and pool surfaces. It may also cause skin and eye irritation. A high PH value can greatly reduce the effectiveness of chlorine and cause the water to become cloudy. To avoid problems, it’s important to try and keep it within the ideal range of 7.4–7.6. This PH test pen will do the job perfectly.
