Seawater refractometer measures saltwater or salinity of water, ideal for aquarium, marine monitoring, fish-keeping,salty pools&spas and etc..
ATC Function: salty water refractometer with automatic temperature compensation, allow you obtain accurate readings easier and faster.
Salinity Refractometer is made of aluminum body and ABS rubber light and very sturdy, comes with a hard plastic case, a mini screwdriver, a dropper.
Easy to Use: put 2-3 drops on the saltwater’s prism, towards light then to get the accurate readings through the optic eyepiece, ideal for replacement the poor quality and difficult to read hydrometer refractometer.

DUAL SCALES - Saltwater Refractometer measures on specific gravity (D20/20) 1.000-1.070 and parts per thousand 0~100‰, you can get the result in two different units by one test.
WIDELY USE - The Refractometer designed for Aquariums, Marine Monitoring, Agricultural and Educational Purposes. Help you to control concentration of salt water easily.
EASY TO USE - Put 2-3 drops of sample solution after calibration on prism, towards light, then get the accurate readings. Aquarium refractometer is ideal for replacement salinity hydrometers or expensive digital salinity tester.
ATC FUNCTION - Aquarium hydrometer features Automatically Temperature Compensate function and always provide you accurate readings fast.
DURABLE & PORTABLE - Saline refractometer is made of aluminum and ABS rubber, anti-rust, non-staining and resistant abrasion, sturdy for long time use. Portable refractometer with plastic case easy to carry.

DUAL SCALE - Salinity Refractometer measures on 2 scales: Specific Gravity 1.000 to 1.070 (D 20/20) and 0-1000PPT, which allow to get the both results at just one testing.
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.

Dissolved oxygen meter is a precision instrument for measuring dissolved oxygen and temperature. The dissolved oxygen probe is a thin film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode but allows oxygen to pass through the membrane to react, and the concentration can be measured..
Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water. The oxygen concentration of our dissolved oxygen meter is 0.0-40.0mg/L, most of the range of dissolved oxygen meters on the market is 0.0-20mg/L. When measuring and calibrating, needn't open the protective cover of the electrode, just put the electrode in the solution for measurement..
Detachable probe, easy to replace, equipped with 6 probe protective covers. The film inside the protective cover cannot be taken apart. After using for a period of time, the test value is inaccurate and the calibration is still inaccurate, and the membrane sleeve needs to be replaced..
Adopts the digital screen display, which is more clear and convenien....

The 86031 Combo Water Testing Meter can measure the pH, Conductivity or TDS or Salinity and Dissolved oxygen depend on which kind of probe attach to the meter or user could attach three kinds of probes at the same time. So the 86031 Multiple Parameters Water Testers could be operated as the pH meter, conductivity meter, TDS meter, Salinity meter or D.O. meter as user needed..
We design different color connector on the meter, user only needs to screw on the probe with the same color, and then get the measuring reading accurate and fast..
User could change the probe or screw on the 86031 Combo Water Quality Measuring Instrument easily. And in order to avoid broken by the stone or particle attacking in the measuring environment, we have developed the specific anti-collision cap on each probe. So the 86031 Combo Water Testing Meter would be the best tool for all professional measuring purposes, including the Aquaculture, Aqua farm, LAB, swimming pool or water treatment business, or other related industry, no matter the fresh or sea water..
AZ 86031 Combo Water Meter- pH/Conductivity/Salt/TDS/D.O was being designed and manufactured by AZ Instrument, a well experienced manufacturer for pH EC Meter..
Large LCD to display multiple parameters simultaneously: pH,....

Test calcium (Ca) and magnesium (Mg) level in water. Suitable for brackish water and seawater with the salinity higher than 5 part per thousand (ppt)..
For freshwater and marine aquarium and aquaculture, pond water, ground water, drinking water.
Ca range from 0 – 800 part per million (ppm) with the resolution of 40 ppm per drop. Mg range from 0 – 1725 ppm with the resolution of 50 ppm per drop..
