Drifting EC readings can throw off an entire nutrient schedule, and a single bad calibration is often the culprit. Aqua Master Tools' EC 1413 Calibration Solution resets your meter to a precise, NIST-traceable benchmark, so every reading afterward reflects what's actually in your reservoir.
Sold as a case of 18 bottles at 100ml each, this larger format is built for shops, commercial growers, or anyone calibrating meters often enough to want a bulk supply on hand rather than reordering single sachets.
Certified EC 1413 μS/cm formulation calibrates meters to a recognized national standard.
Ships as a case of 18 bottles, ideal for frequent calibration or commercial use.
A larger volume per bottle than single-use sachets, suited to repeated calibrations.
Stays accurate when stored between 15-25°C, ideal for grow rooms, tents, and labs.
| Specification | Value |
|---|---|
| Solution Type | EC 1413 Calibration Solution |
| Volume per Bottle | 100 ml |
| Bottles per Case | 18 |
| Standard | NIST-Traceable |
| Storage Temperature | 15 – 25 °C |
This case includes 18 bottles of 100ml EC 1413 calibration solution.
Once opened, close the bottle immediately after use and do not return used liquid to the bottle, as this can introduce contamination and affect calibration accuracy.
EC 1413 refers to the solution's electrical conductivity value of 1413 μS/cm, a standard reference point used to calibrate EC and TDS meters.
Keep bottles sealed and store them between 15-25°C, away from direct sunlight and extreme temperatures, to preserve accuracy until use.
Yes, EC 1413 is a widely used industry-standard calibration point, making it compatible with most consumer and commercial EC and TDS meters.
For frequent or commercial use, a bulk 100ml case typically offers more solution per dollar than individual 20ml sachets, while still maintaining the same NIST-traceable accuracy.
