Aqua Master Tools Calibration Solution EC 1413 - 100 ml - 18 Count

Keep EC Readings Trustworthy With a Traceable Standard - 18 Bottles

EC meters drift over time, and drifting readings lead to wrong nutrient decisions. This EC 1413 calibration solution gives you a known reference to set your meter against. It is traceable to a NIST standard, so you can calibrate against a documented reference.

This unit holds 18 bottles of 100 ml each. That suits growers who calibrate meters regularly, run several meters, or want fresh solution on hand for every session in a hydroponic setup.

Key Features & Benefits

• EC 1413 standard — a common reference point for calibrating EC meters.
• Traceable to NIST standard — gives your calibration a documented reference.
• 100 ml bottles — a small volume per bottle, so you can open a fresh one for each calibration.
• 18 bottles per unit — stock for repeated calibrations across a season or several meters.

Who Should Use Aqua Master Tools Calibration Solution EC 1413

Anyone who measures nutrient solution strength in hydroponic systems: home growers checking a single meter and commercial teams maintaining several.

Frequently Asked Questions

Q: What is EC 1413 calibration solution?
A: It is a reference liquid with a known electrical conductivity value of 1413. You place your EC meter in it and adjust the meter to read that value.

Q: How should I store it?
A: Store it between 15 and 25 °C. Close the bottle immediately after each use.

Q: Can I pour used solution back into the bottle?
A: No. Do not return liquid to the bottle, because contamination would make the standard unreliable.

Q: What does traceable to a NIST standard mean?
A: It means the solution's value can be linked back to a reference standard maintained by NIST. This supports confidence in your calibration.

Q: How many bottles come in a unit?
A: One unit contains 18 bottles of 100 ml each.
