This MA991B/1 replacement probe for the Milwaukee MC100T meter is the original spare part for this pH meter.
The probes are durable and resistant but like all things it will eventually come to the end of its useful life, obliging us to replace the probe with a new one in order to continue enjoying precise and fast measurements.
To swap over the probe with 1m cable, simply disconnect it from the meter and replace it with the new one. When using a new probe it is always advisable to perform a calibration to ensure accurate pH readings.
