Quick and Easy pH Meter

This little device gives you a near instant reading of your aquarium pH without requiring the use of consumable liquid reagents or disposable test strips.
 
Keeping frequent tabs on your pH will ensure that your plants and animals are healthy and that your CO2 injection is safe and effective.
 
Each pen includes packets for making calibration solutions at pH 4.04 and 6.86 to ensure that your readings are accurate.
 
Note: Temperature can affect your pH readings so readings done with very cold or very hot water may not be correct. This pen is calibrated to work best at 25C but room temperature or slightly warmer aquarium water is in the acceptable temperature range.
