Ammonia Alert is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It las..
This kit measures total (NH3 and NH4+) and free ammonia (NH3 only) down to less than 0.05 mg/L and is virtually interference free in marine and fresh water. Free ammonia is the toxic form of ammonia (vs. ionized Ammonia NH4+ which is non-toxic) and thus it is much more important to keep an eye on the level of free ammonia in your system.
This kit is based on the same gas..
This kit measures copper (all types) to less than 0.01 mg/L in marine or freshwater. Uses a highly sensitive catalysis based procedure. MultiTest Copper performs over 75 tests and contains a reference sample for validation.
This kit combines the Marine pH & Alkalinity, Ammonia and Nitrite & Nitrate kits into one kit. MultiTest Marine Basic performs over 75 tests and contains a reference sample for validation.
Multi-cavity plate for simultaneous testing of up to 6 tests at the same time.
Sensor based, sensitive to less than 0.01 mg/L.
This kit measures nitrite to less than 0.1 mg/L and nitrate to less than 0.2 mg/L in marine or freshwater. MultiTest Nitrite. Nitrate performs over 75 tests and contains a reference sample for validation.
This test kit features a unique dye that has a pronounced color change between 8.0 and 8.3, making it the easiest kit on the market to read in that critical range. Alkalinity may be read from the same sample in 0.5 meq/L increments. MultiTest Marine pH & Alkalinity performs over 75 tests and contains a reference sample for validation.
This kit measures all types of calcium, including gluconate calcium. The method is based on specific titration with a unique indicator.
Rapid and simple 3 step procedure.
Precise to 5 mg/L.
Includes reference validation.
Designed for the reef aquarist.
