Frequently Asked Questions

What meter is this sensor compatible with?

It's a replacement TDS/EC sensor built specifically for the HM Digital HM-200. Confirm your meter model before ordering, since HM Digital sensors are model-specific.

When should I replace my HM-200's sensor?

If your HM-200 starts giving drifting or inconsistent TDS/EC readings even after recalibration, a worn sensor is a common cause. Swapping in a fresh sensor is the standard fix before considering a full meter replacement.

Do I need to replace the whole meter instead?

No, the HM-200 is designed with a replaceable sensor, so you can restore accuracy by swapping just the sensor. That's typically far less costly than buying a new meter.

Is installation straightforward?

Yes, the sensor is designed as a direct swap-in replacement for the HM-200's original component. Refer to your HM-200's manual for the exact connection steps.
