Aqua Master Tools Calibration Solution EC 1413 - 500 ml - 8 Count

Keep EC Readings Trustworthy - 500 ml Bottles

An EC meter that drifts leads to feeding mistakes in vegetative growth and flowering. This calibration solution gives you a known EC 1413 reference to set your meter against, and it is traceable to a NIST standard, so you can trust the reference value.

This unit holds 8 bottles of 500 ml each. That suits growers who calibrate often, run several meters, or manage more than one room, and it keeps a spare on the shelf.

Key Features & Benefits

• EC 1413 reference value — a standard point for calibrating conductivity meters.
• Traceable to NIST standard — a documented basis for your readings.
• 500 ml bottles — enough solution for many calibrations.
• 8 bottles per unit — stock for regular use or multiple meters.

Who Should Use Aqua Master Tools EC 1413 Calibration Solution

Growers who measure nutrient strength in hydroponic systems, from home gardeners with one meter to commercial operations with several, will find it useful.

Frequently Asked Questions

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

Q: Can I pour used solution back into the bottle?
A: No. Do not return liquid to the bottle, because it can contaminate the remaining solution and shift its value.

Q: What does NIST traceable mean?
A: It means the solution's value can be linked to a recognized national measurement standard. That gives you a dependable reference for calibration.

Q: How many bottles come in a unit?
A: The unit contains 8 bottles of 500 ml each.

Q: Why calibrate an EC meter?
A: Probes drift over time, so readings become less accurate. Calibrating against a known solution corrects that and supports consistent nutrient feeding.
