The Neptune Systems Apex Double Junction Lab Grade pH Probe holds calibration longer and has a longer lifespan than single junction probes. Double junction probes have a second vessel inside the main electrolyte with a second internal junction. This means that even when the aquarium water eventually begins to make its way into the first compartment, it still has to go through the second junction to contaminate the electrolyte surrounding the reference electrode. They're included with the Neptune Systems Apex System Gold (New Style) w/ Energy Bar 832.

Professional Automatic Temperature Compensation Sea Water Salinity Refractometer for Aquarium, Hydrometer, 0-100ppt & 1.000-1.070 Salinity Specific Gravity
Manufacturer: Magnum Media
Brand: Magnum Media Salinity 10ATC
Brand new Salinity Refractometer that is used to measure the salinity levels of saltwater aquariums and the worlds oceans.
Calibrate with either distilled water or a 35ppt Salinity standard.
Wipe off the saltwater after each use.
This unit comes with Automatic Temperature Compensation or "ATC". This feature allows you to get a reading outdoors when the temp is between 50'F-86" (10'C-30'C). If you test outside of temp range your readings will become gradually more and more inaccurate. For best results, test indoors.
No batteries necessary as you only need strong light - daylight (sunny or cloudy) or a lamp/flashlight.
HM Digital COM100 Waterproof EC/TDS And Temperature Combo Meter
Manufacturer: HM Digital
Brand: HM Digital
Product description: HM Digital's COM-100 is a waterproof combination EC/TDS/Temperature meter that is ideal for all water quality testing, water purification applications, drinking water, wastewater regulation, aquaculture, hydroponics, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more. The COM-100 is a professional level EC/TDS meter at an unbeatable price.
Fluval Sea Hydrometer provides an accurate and convenient method of measuring specific gravity and salt level in marine aquariums. Regular testing is strongly recommended as stable salinity levels are essential for the health of marine fish and invertebrates. Compact and easy to use, the hydrometer can be permanently installed inside the tank for continuous readings. Its slim, low-profile design camouflages well inside the tank and will not diminish the aesthetics of the aquarium. It can also be used as a portable device, allowing you to take samples simply by submerging it in the water. The Fluval Sea Hydrometer features large, easy-to-read markings with ideal salinity range clearly marked in green for clarity.
