HYDROS pH 7.1 Calibration Fluid

Nearly all HYDROS pH sensors and controllers require two reference points to monitor accurately the pH the probe is measuring. You should make use of calibration solutions that fall within the range that corresponds to the pH level you want to be monitoring. In reef tanks, where the pH range is usually 7.8-8.5 then you'll need to make use of calibrators between 7.0 as well as 10.01. For calcium reactors that are installed on freshwater aquariums or saltwater tanks in which the pH is typically lower than 7.0 it is recommended to utilize 4.01 and 7.01 to calibrate the probe. 7.01 pH -A Neutral pH calibration packet. This is the standard used by nearly all pH monitors and controllers to perform calibration. Calibration packs can be stored in a dry and cool location for up to one year.
