TRIS compatible, rugged, and convenient

Optimal for lab use and precise Q.C. measurements.

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

Single-junction models with Ag/AgCl reference element

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

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

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

Combination electrode with built-in ATC probe

Ideal for measurements in small vessels or with small samples

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

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

Single-junction Ag/AgCl flat surface model

Fast, accurate response despite temperature changes

For easy measurement of small samples in long and narrow vessels.

Large junction for increased flow, minimal clogging

Conduct precise pH determinations with this general purpose, top performance glass body combination electrode with waterproof BNC connector.

Conduct precise pH determinations with this general purpose, top performance glass body combination electrode with waterproof BNC connector.

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

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.

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

Get results three to five times more precise than those obtained with conventional electrodes with the Thermo Scientific™ Orion 815600 ROSS Combination pH Electrode.
