Here’s a brief summary of the EC level test procedure:

- Prepare the Sample: Mix the sample well and filter if needed.
- Calibrate the Meter: Use a known calibration solution to set the EC meter.
- Measure EC: Rinse the probe, immerse it in the sample, and wait for the reading to stabilize.
- Clean the Probe: Rinse with distilled water after measurement and store as recommended.
- Interpret Results: Compare the EC value to relevant standards.

Regularly calibrate and maintain your EC meter for accurate results.
