Aqua Master Tools EC 1413 calibration solution

EC 1413 calibration solution from Aqua Master Tools in a 100 ml or 500 ml bottle, for calibrating your EC meter.

EC 1413 (1.413 mS/cm) is the most widely used EC calibration value. It sits close to the EC of an ordinary nutrient solution, so you calibrate right in the range you measure in. The H600 Pro calibrates automatically at this value, and for pens with manual EC calibration it is the obvious choice.

How to calibrate well

Pour a little solution into a clean cup and calibrate in that, not in the bottle. Let the meter reach the solution's temperature: EC depends strongly on temperature, and the value on the label applies at 25 °C. Throw used solution away and never pour it back into the bottle. Close the bottle straight after use.

Technical specifications:

• EC value: 1.413 mS/cm (at 25 °C)
• Volume: 100 ml or 500 ml
• Traceable to: NIST standard
• Storage: between 15 and 25 °C, bottle tightly closed
• Model number: AMT1101 (100 ml), AMT1301 (500 ml)

Frequently asked questions

Which EC calibration solution do I need?
Check your meter's manual. Meters with manual EC calibration (such as the E50 Pro2 and P110 Pro2) can be calibrated with any value; EC 1413 is then the most common.

Does it work with meters from other brands?
Yes, if your meter can calibrate at 1.413 mS/cm.
