My package arrived earlier than I expected.

This durable pH electrode was purchased to replace the glass electrode that came with our HI2221 pH meter. We are a brewery and so we needed a more durable electrode for floor operations. The BNC+Pin means the meter is still able to monitor the response time & alert us when the electrode needs to be cleaned or replaced which is super helpful.
