Quick Cal Solution Solution for GroLine pH and EC Meters - 500 ml

HI9814P is a quick calibration solution for use with Hanna’s HI9814 GroPro portable pH/EC/TDS meter. This solution allows for the quick single point calibration for pH and conductivity. Each sachet has the lot number and expiration date stamped on it and is made of light block foil ensuring freshness each time one is opened. Hanna’s line of calibration solutions have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened sachet.

pH and PPM/EC meters should be calibrated frequently (every 1-4 weeks, depending on use). Do not reuse calibration solution, as once it has been used, it is no longer sterile and may result in improper readings. Pour a small amount into a shot glass and discard after use, or use Hanna's single use sachets for ease of use.
