For routine pH and titration measurements with small samples and small vessels, where separate half-cell electrodes may be impractical

Rugged polymer construction for handheld use with aqueous samples in the classroom or in the field

Dual junctions provide fast response and long life in paper pulp testing

Measure general pH samples as well as viscous or colloidal samples with the Thermo Scientific™ Orion™ 8172BNWP ROSS™ Sure-Flow™ pH Electrode.

Combination electrode with built-in ATC probe

Single-junction Ag/AgCl flat surface model

Measure biological media, pharmaceuticals, foods and more with Thermo Scientific™ Orion™ ROSS Ultra™ Refillable pH/ATC Triode™ Combination Electrodes.

Replacement/accessory for accumet AP85, AP84, AP72, AP71 Portable Meters

Ideal for measurements in small vessels or with small samples

The Thermo Scientific™ Orion™ 9165BNWP Combination Sure-Flow pH Electrode is a combination pH electrode with epoxy body for fast response in difficult samples and soils.

Ideal for meaurement in thick or viscous samples, but compatible with all sample types. 

Precisely perform pH determinations with this general purpose, top performance, epoxy body combination electrode.

Used with AB15+ and AB15 kit for routine pH and titration measurements of aqueous solutions with small samples, small vessels.

For measuring pH in small vessels.

Conduct routine pH measurements with the Thermo Scientific™ Orion™ Economy Series pH Combination Electrode, a routine wick junction, gel-filled electrode.

Large junction for increased flow, minimal clogging

With intelligent Sensor Management technology.

Offer outstanding price/performance ratio. Mettler Toledo Economy Series pH and pH/ATC Combination Electrodes are cost-effective alternative for less-demanding requirements.

Ideal for critical samples such as suspensions or samples of unknown composition. Mettler Toledo Expert Series pH and pH/ATC Combination Electrodes with open junction puts the reference electrode in direct contact with the measured medium, eliminating the possibility of contamination or blockage.

Large junction for increased flow, minimal clogging

A combination pH electrode with MultiPin head and integrated temperature probe designed for measuring samples with a tough exterior. Mettler Toledo InLab Solids Pro ISM pH Sensors have solid polymeric electrolyte which requires no junction at all, making them particularly insensitive to contamination.

Replace Oakton™ pH and pH/Conductivity Electrodes when they break, no longer hold calibration, cannot be rehydrated, or are not compatible with your sample.

Can be optimal for lab use and precise Q.C. measurements.

No more waiting for pH readings to stabilize when measuring samples of varying temperatures.

Perform accurate, reproducible pH calibrations with the Thermo Scientific™ Orion pH Buffer Bottles.

Operate this highly-versatile probe in either the field or a plant.
