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 equipment like the Aqua Master Tools P160 Pro Combo Pen to a precise, NIST-traceable benchmark, so every reading afterward reflects what's actually in your reservoir.
Sold as a case of 8 bottles at 500ml each, this large-volume format is built for shops, commercial growers, or labs calibrating meters often enough to justify a bulk supply over smaller bottles or individual 20ml sachets.
Certified EC 1413 μS/cm formulation calibrates meters such as the Aqua Master Tools P700 Pro 2 Combo Meter to a recognized national standard.
Ships as a case of 8 bottles, ideal for frequent calibration or commercial use.
A large volume per bottle, cutting down on how often you need to reorder.
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 | 500 ml |
| Bottles per Case | 8 |
| Standard | NIST-Traceable |
| Storage Temperature | 15 – 25 °C |
This case includes 8 bottles of 500ml 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 high-volume or commercial use, a bulk 500ml case typically offers more solution per dollar than smaller bottles or individual 20ml sachets, while maintaining the same NIST-traceable accuracy.
