The long-term tests are made of high-quality crystal glass and are suitable for permanent and direct CO2 measurement in the aquarium. Available is Small/Medium/Large.

The Sera Fe (iron) test is to quickly and easily determine the iron level in your water. Good for +- 75 tests.

Makes it easy to monitor the pH value in fresh and marine water and ponds. For approx. 100 measurements.

The performance of conductivity probes are affected by use due to residue build up and aging. M10032B is a lab grade 1382 ppm TDS solution standard prepared against a NIST traceable potassium chloride solution that allows you to recalibrate your conducti

The level of CO2 in the aquarium can be read directly from the six-colour scale in milligrams per litre. This provides an absolutely simple and reliable means of setting the correct CO2 supply level.

The sera O2-Test monitors the actual oxygen level in the water within minutes and allows for acting in time up on oxygen deficiency.

CO2 is one of the most important nutrients for aquarium plants. With the Co2 continuous test of Sera, you can easily and quickly determine the CO2 content of your aquarium water.
