LiveNH3 Refill Cartridges
Directions for Use: Simply remove the existing cartridge from your Live Meter device and discard. Slide the new Refill Cartridge into the slot until you hear it snap into place. The NH3 sensor will begin monitoring ammonia levels immediately.
Compare the active membrane to the color reference blocks to determine if action is needed to maintain healthy water. Adjust Month/Date Slide Indicators to indicate when it is time to replace the monitor - approximately every six weeks. For use in freshwater only.
