Customers continually complain that they have broken the bulb of their P11 Glass Combination electrode. They ask why Glass probes do not have a bulb protector like Epoxy body probes.
It is true that we do have a Bulb protector, which is listed in our Catalogue under reference – 743-01. Problem is that it is expensive, and costs more than the price of the electrode.
However, Sentek (UK) have come up with a lower cost option. This is a Protected Bulb Probe. It is essentially a P11, but the bulb is protected, as can be seen below.
We showed this at Achema, where it was received with great enthusiasm.
Obviously, it is more expensive than a P11, but considerably less expensive than a standard P11 with the 743-01 bulb protector.
For customer seeking this type of probe, we now have the answer.
