JOR Refractometer, Dual-Range Scale Device to Measure Salinity and Specific Gravity of Saltwater Aquarium and Reef Tank, Provides Accurate Reading, No Batteries Required, 1 Set per Piece

• Dual-Range Scale Refractometer --- A healthy saltwater aquarium requires a salinity balance or the salt concentration in aquarium water. Refractometer by JOR helps maintain this fundamental parameter in your saltwater aquarium or reef tank, measuring both salt percentage and specific gravity. This measuring tool has a scale range of 0 to 100%, where 1% means one part per thousand (PPT) or 1000 parts per million (PPM) and with a corresponding specific gravity range of 1.000 to 1.070..
• Provides Accurate Measurement Reading --- Forget guessing and estimating. This handy refractometer features automatic temperature compensation that gives precise, faster and easier readings..
• Easy To Use --- Place 2 to 3 drops of aquarium water on the glass, then close the plastic cover. Look through the eyepiece as you hold it under a light source. Check the reading. The blue line indicates the exact salinity level..
• High Quality And Economical --- This premium quality handheld refractometer has an aluminum alloy body, rubber grip, and adjustable focus. It doesn’t corrode, and since it is analog, it can also save you money because it doesn’t need batteries to operate, sparing you from buying replacements..
• Complete Care Set --- This portable measuring device c....

• EASY TO USE - The aquarium refractometer need few sample, put 2-3 drops on prism and towards light source, you can get the the accurate readings quickly from eyepiece.
• WIDELY APPLICATION - Brine refractometer can be used for measuring salt water, salinity of water and seawater, ideal for monitoring aquariums, Marine Fishing Keeping, Agricultural, lab experiment and Educational purposes.
• ACCURATE & AFFORDABLE - Salt water refractometer features ATC (Automatic temperature compensation) function to ensure get consistently accurate reading. Easy to operate than traditional hydrometers and more affordable than digital refractometer.
• DURABLE & PORTABLE - Saline (brine) refractometer is made of aluminium and rubber, non-rust, anti-abrasion and durable for long time use. Comes with plastic storage box, small screwdriver and cleaning cloth, easy to organize and carry with.

YCKYIGO Salt Water Pool Tester Large Range 7 in 1 Multi-Parameter Tester for Salt Swimming Pool and Spa

• 【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....

Professional Automatic Temperature Compensation Salinity Refractometer for Aquariums Marine Monitoring Saltwater Testing.Dual Sacle 0-100ppt & 1.000-1.070 Specific Gravity

Yosoo123 Accurate Automatic Hydrometer SaltSalinity Meter Salinimeter for Fish Tank (Square Type)

• Insert the gravity into the tank or the fish pond below 15 cm until thespills the plate. (slowly fillingto prevent bubbles attached to the pointer).
• When thereaches the full state (and the top level of the baffle), take out the hydrometer and place it on a horizontal surface..
• The air bubbles attached to the needle will lead to inaccurate reading, carefully pending the gravimeter to shock the adherent bubbles..
• Read the specific gravity according to the inner scale, and read out the salinity (PPT) according to the outside scale. We recommend that the seadensity of the seafood pool is between 1.020-1.023, that is the safety line..
• It is easy to read and thecan be + (-) 0.001 units of specific gravity. Professional design make it able to get accurate reading when the temperature of theis at 18 degrees -28 degrees.

Hanna Salinity Tester HI98319

• 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..
