TDS and 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 the single use sachets.
TDS and EC Calibration Solution is available in a variety of sizes ranging from single-use sachets to quart bottles. All calibration solutions we offer are made by either Hanna or General Hydroponics.
The 1413 mS/cm Calibration Solution is used to calibrate EC meters.
