Replacement Probe MA991B/1 for MW101-SOIL PRO

This MA991B/1 replacement probe for the MW101-SOIL PRO pH meter is the original spare part for this pH meter.

The probes are durable and tough, but like all things they will eventually reach the end of their service life, requiring us to replace the probe with a new one to keep enjoying accurate, fast measurements.

To change the probe with its 1 m cable, simply disconnect it from the meter and replace it with a new one. When using a new probe, it is always advisable to calibrate to ensure accurate pH readings.
