Feed & EC
EC readings do not match
First compare the test methods, then compare the numbers. A supplier’s extraction result and drainage from a fertigated crop describe different samples.

Why does an inline EC sensor disagree with my handheld meter?
Compare both instruments on the same solution under stable conditions.

Why the root zone matters
A control sensor can influence every fertigation event in a coir crop.
01 / OBSERVE
Three checks before you change anything
- Check calibration history and temperature settings for both instruments.
- Take a sample close to the inline measurement point at the same time.
- Inspect the inline sensor for fouling, air exposure or installation issues using its manual.
02 / NARROW IT DOWN
Which result is suspect?
Choose the closest observation for a suggested next check.
Handheld fails its standard check
Correct the handheld measurement before adjusting the controller.
Inline reading remains inconsistent
Have the control sensor cleaned or serviced and verify its output independently.
Both pass but samples differ
Investigate sampling location and timing along the delivery path.
03 / TAKE THE NEXT STEP
Leave with something useful
Keep a paired-reading log after corrective maintenance.
Keep in mind
Do not recalibrate an inline controller against an unverified handheld result.
