Aqua Master Tools Calibration Solution - EC 1413 - 20 ml Sachet - 25 Count

Fresh EC Reference for Every Calibration - 25 Sachets

An EC meter that drifts gives you unreliable nutrient readings, and a reused or contaminated calibration liquid makes that worse. This solution comes in single-use 20 ml sachets, so each calibration starts with clean liquid at a known EC 1413 value. It is traceable to a NIST standard.

Each unit holds 25 sachets of 20 ml. That suits indoor growers who calibrate regularly and small commercial rooms that want a ready supply without opening a large bottle that can degrade or pick up contamination.

Key Features & Benefits

• EC 1413 reference value — a common single-point value for calibrating EC meters used with nutrient solutions.
• Single-use 20 ml sachets — each calibration uses fresh liquid, so you avoid cross-contamination.
• NIST traceability — the standard behind the solution is traceable, supporting record keeping.
• 25 sachets per unit — a stock of calibrations from one purchase.

Who Should Use Aqua Master Tools EC 1413 Calibration Solution

Anyone who measures nutrient strength in hydroponic systems: home gardeners checking a handheld meter, and licensed commercial growers who calibrate on a schedule and keep records.

About Aqua Master Tools EC 1413 Calibration Solution

Aqua Master Tools makes this EC 1413 calibration solution in 20 ml sachets. Each unit contains 25 sachets. Store it between 15 and 25 °C and do not reuse the liquid.

Frequently Asked Questions

Q: Can I reuse the solution after calibrating?
A: No. Discard the liquid after use. Reused solution picks up residue from the probe and can shift its value, which defeats the calibration.

Q: How should I store the sachets?
A: Keep them between 15 and 25 °C. Keep them sealed until you are ready to calibrate.

Q: What does EC 1413 mean?
A: EC is electrical conductivity, a measure of dissolved salts in a solution. The 1413 is the reference value this solution provides for your meter to read.

Q: Why use sachets instead of a bottle?
A: A sachet gives you a fresh measured portion each time. A bottle that is opened repeatedly can be contaminated or change over time.

Q: What does NIST traceable mean?
A: It means the solution's value can be linked back to a standard maintained by the National Institute of Standards and Technology. This helps if you document your calibration practice.
