Usage guide
Calibrating your EC tester with our 1413 µS/cm solution is simple and quick. Always start by carefully rinsing your tester probe with deionised water to avoid any contamination. Then open a 20 ml sachet or pour a small amount of calibration solution into a clean beaker. Immerse the probe in the solution, making sure the temperature is close to 25°C for maximum accuracy. Gently swirl to eliminate air bubbles and wait 1 to 2 minutes for the reading to stabilise. Activate the CAL mode on your tester and adjust it until it displays 1413 µS/cm. Remember to rinse the probe again with deionised water after each use to keep it clean and extend its lifespan. Avoid dipping the probe directly into the original bottle to prevent contaminating the remaining solution.
Compatibility and Pairings
This 1413 µS/cm calibration solution is compatible with a wide range of EC testers, including Hanna models (such as the HI98129), Milwaukee, and most generic devices. It can also be used for TDS modes (for example, 1382 ppm with a factor of 0.5). It is an essential product for pH/EC/TDS combo meters in indoor horticulture. For complete maintenance of your equipment, we recommend pairing it with an EC Calibration and Maintenance Kit. If you need standards for higher conductivity ranges, you might be interested in an EC Calibration Solution 2.8 mS/cm. For larger volumes, we also carry the EC Calibration Solution 1,413 µS/cm - 300 mL - IONICS.
Frequently Asked Questions
How do I calibrate an EC tester with the 1413 µS/cm solution?
To calibrate your tester, rinse the probe with demineralised water, immerse it in the solution at 25°C, swirl gently, wait for stabilisation, then activate CAL mode and adjust to 1413 µS/cm. Rinse the probe after use.
What is the ideal temperature for calibrating at 1413 µS/cm?
The ideal temperature for accurate calibration is 25°C. A significant deviation can skew results, even if many testers feature automatic temperature compensation.
Should I use a 1413 µS/cm or 12.88 mS/cm solution for my tester?
It depends on your tester's measurement range and the manufacturer's recommendations. The 1413 µS/cm solution is a common standard for mid-range devices, while 12.88 mS/cm is often used as a primary standard for higher conductivity ranges. Check your device's manual.
Where to buy a reliable EC 1413 calibration solution?
You can buy reliable EC 1413 µS/cm calibration solutions at GrowLED. We offer quality, NIST-traceable products to ensure the accuracy of your measurements.
Why is it important to calibrate my EC tester regularly?
Regular calibration, ideally monthly or before every critical measurement session, is essential to maintain the accuracy of your EC tester. It ensures that your nutrient readings are precise, which is vital for the healthy growth of your plants and the optimisation of your crops.
