Product Information

JBL Permanent Test CO2/pH.

This permanent test will give constant readings of the CO2 and pH values in your aquarium.

The test lasts around 9-12 months, and offers a precise reading via an indicator pane that sits in the test unit. This disposable indicator needs to be replaced every 3-4 weeks.

The CO2 level is imperative for lush plants. This efficient test will constantly measure the level of carbon dioxide and provide results via the indicator pane. CO2 diffuses via the water into the test unit, which changes the colour of the indicator patch, and as a result the pH reading too.

The pH value is important, as the right balance in your aquarium is vital for healthy plant growth. The JBL Permanent Test offers a pH value range of 6.4 - 7.8, so you can be sure of the most sensitive, reliable reading. The pH value will only offer the reading reached via the CO2, as it can be affected by other factors such as peat.

Two separate colour scales, one for pH and the other for CO2, are included with the unit to be attached to the pane of the aquarium, as required.

Key Features:

  • Lasts 9-12 months
  • Permanent fixture in aquarium for constant results
  • 2 X 10ml test reagents
  • Test unit with suckers
