Temperature compensated refractometer for the determination of salinity

salimeter is a density meter

accurate measurement of Dissolved Silica - for marine aquariums & tap water

• 2 x 25 ml, 1 x 10 ml

3 x reagent 3 for the sera magnesium Test

• 3 x 15 ml

The sera nitrite-Test makes it easy to determine the level of toxic nitrite.

• For approx. 75 measurements in fresh and salt water.

The Sera nitrite-test: Use during regular maintance to check the nitrite level in fresh-and saltwater aquariums and garden ponds. (...)

Fertilization according to the requirements of the plants is only possible if the iron level is monitored.

• For approx. 75 measurements

Compare the test results with the supplied color chart to obtain the iron level. (...)

For regularly checking the nitrate level in aquarium water.

• ca. 60 Tests
• Detect unwanted nitrate-simply,quickly and reliably by means of the sera-Test.
• Nitrate levels exceeding 50mg/l (ppM) promotes heavy algae growth and also sunts the growth of fish and plants. (...)

This test monitors the calcium level easily and precisely in steps of 20 mg/l (ppm).

• ca. 7.500 mg Ca
• The calcium level in saltwater can easily and safely be determined by using the sera calcium-Test.
• If the level falls below 400 mg/l (ppm), the calcium concentration can be increased with sera calcium plus. (...)

Makes it easy to monitor the carbonate hardness in fresh and salt water.

• ca. 420° dKH

Carbonate hardness (KH) stabilizes the pH value. (...)

Makes it easy to monitor the pH value in fresh and salt water and ponds.

• For approx. 100 measurements.

To achieve a stable pH value, ensure to maintain the carbonate hardness of at least 4°dKH. (...)

For approx. 60 measurements.

• Phosphate strongly promotes algae growth.
• Thus, it should be regularly checked by means of the sera phosphate-Test and be removed in freshwater with sera phosvec.
• The phosphate level should be below 1 mg/l (ppm) in freshwater resp. 0.1 mg/l (ppm) in saltwater. (...)

For monitoring chlorine in aquarium water.

• Chlorine is rapidly removed by sera chlorvec.

The sera chlorine-Test tells you whether the chlorine level is dangerous by simply comparing colors. (...)

• Zeigt den Gehalt an zweiwertigem Eisen an.

Test for measuring the nitrite content in freshwater and seawater.

Test for nitrate content in freshwater and seawater.

Test for measuring the phosphate content in freshwater and seawater.

Test for measuring the calcium content in freshwater and seawater.

60-second test for fresh water and sea water aquaria

Important when:

• setting up a new aquarium
• changing the water
• carrying out CO2 fertilization (...)

Measures the ammonia value reliably and precisely

• for both freshwater and marine aquariums
• for a large number of analyses
• excellent long-term stability (...)
