Atlas Scientific Lab Grade pH Probe - BNC, Replaceable Reference 7 inch 5 mm A/V jack (compositeGet Precise pH Readings with a Lab Grade Probe The Atlas Scientific Lab Grade pH Probe is built for high accuracy pH measurement in demanding lab and engineering work. It uses a double junction design and a Vanadium III tip to improve stability and reduce noise during measurement. Atlas also highlights the Tyvek junction design, which helps hold internal electrolyte longer and supports longer periods between recalibration in the right applications.
