PINPOINT II Oxygen Monitor™ will quickly and accurately display a digital readout for dissolved oxygen in either % oxygen or ppm saturation. The measurement range is 00.0 – 20.0 ppm. The probe is a high performance polarographic type, which uses pre-loaded Teflon membrane caps and electrolyte fluid. This is the #1 preferred oxygen monitor in the aquaculture industry. The PINPOINT II Oxygen Monitor™ is an extremely good value, considering its high precision and ruggedness. The PINPOINT II Oxygen Monitor™ comes complete with Membrane caps and electrolyte fluid, probe with 5-foot cable and meter. Extra Membrane Cap/Fluid kits are available, and the 4-meter probe extension cord is an optional accessory. The commercial aquaculture market purchases a significant number of these units on a very regular basis.
Our mission
Fish Tanks Direct Specializes in Acrylic Aquariums delivered right from the factory floor. Save thousands of dollars off of your next custom acrylic aquarium by shopping with us. We have been in the Fish Tanks industry for over 20 years and we have knowledgeable staff that will be happy to pick out the perfect acrylic aquarium for your home. Don't forget to shop by shape! We have a wide assortment of shapes that you can choose from which come in many of the popular sizes. Our customized fish tanks do not come with stand or canopy so you will have to order them separately. Many of the wood stains are minwax colors so check your local hardware store to see the actual color as the web can distort the actual color.
We also carry a full line of filters for your aquarium. We can perfectly match your aquarium up with a powerful protein skimmer and or canister filter. It is critical that you have proper filtration when purchasing your acrylic fish tank. Advanced hobbyists can take advantage of our low cost aquarium chillers.
