Apera 201-C Combination pH Electrode (AI1301) — Polycarbonate-Body with BNC Connector

The Apera 201-C (AI1301) combination pH electrode uses a proprietary lithium glass membrane for fast, stable pH measurements. It features 50 Ohm low impedance for quick response times and employs a Gel KCL electrolyte, so there is no need for refilling. A detachable sensor shield covers the delicate glass membrane to guard against accidental damage, and the probe mounts via a standard BNC connector. Housed in a durable polycarbonate-body for everyday laboratory and field use.
