Made of high quality plastic, aquarium transparent, automatic accurate reading brine hydrometer.
Accurate, durable and easy to read salt and specific gravity of your marine aquarium, small and waterproof. If the specific gravity is between 1.000-1.019, it indicates that the specific gravity is low.
if the specific gravity is between 1.020-1.023, it indicates that the specific gravity is normal.
if the specific gravity is between 1.024-1.030, it indicates that the specific gravity is high.
The external range of the scale indicates salinity (PPT), and the internal range of the scale indicates gravity. And clearly mark the safe area. Application range: 0-40 degrees (1.000-1.030). If the salinity PPT is between 32-40, it indicates that the salinity is high.
if the salinity PPT is between 27-31, it indicates that the salinity is normal.
if the salinity PPT is between 0-26, it indicates that the salinity hydrometer is low.
Wide range of applications: Suitable for salt water and sea water fish tanks. Perfect for testing salinity and specific gravity of saltwater and seawater tanks, including solubility and specific gravity scales. Suitable for fresh water and sea water.
Easy to read swing arm pointer and ultra wide stable base can provide accurate test results.

It is designed for the measurement of seawater or low concentrated saltwater..
Dual scale: 0-100‰ salinity and corresponding specific gravity 1.000-1.070.
Automatic temperature compensation function minimizes the effect of the temperature on testing result..
Easy to Use: It's very easy to use even for new users. And no battery needed..
Ideal for marine fishkeeping aquarium, saltwater pool, marine monitoring,lab,agricultural, gardening and educational purposes..

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..

【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%..
【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..
【Platinum Electrodes for TDS】Total Dissolved Solids (TDS) is a measurement of all dissolved solids in pool water. The higher the TDS reading, the harder it is to maintain clea....
