Waterproof pH Meter with 0.1 Resolution

Manufacturer: COLE-PARMER Brand: Cole-Parmer

Match these combination electrodes with one of the connector cables listed at the right. If you use several pH meters that each have different connector types, these electrodes and cables can save you money. The probe-cable interface is moisture proof and noise free, with a sealing O-ring, gold-plated contacts, and PTFE insulation. Save space and money by using one cable with multiple electrodes or vice versa Cable cap rotates independently and will not bunch up
