Neptune Systems Apex Double Junction Lab Grade pH Probe
Manufacturer: Neptune Systems
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.
