pH Electrodes Products & Reviews

Receive stable readings to 0.01 pH in less than 30 seconds with the Thermo Scientific™ Orion™ ROSS™ Combination Semi-micro pH electrode. The semi-micro tip fits test tubes and helps measure samples as small as 0.2 mL. Results are three to five times more precise than those obtained with conventional electrodes, even in extreme cases of samples varying from one another by 50°C or more. Drift is less than 0.002 pH per day, rest…

Get stable readings to 0.01 pH in less than 30 seconds with the Thermo Scientific™ Orion™ ROSS™ Combination Flat Surface pH Electrode. This electrode measures pH of soft, moist surfaces - both solid and semi-solid - such as agar gel plates, meats, bread dough and similar samples. It's results are three to five times more precise than those obtained with conventional electrodes, even in extreme cases of samples varying from on…

Ideal for pH measurement in semi-solid food material, such as cheese, meat, fruit, bread and other similar samples, calculate results three to five times more precise than those obtained with conventional electrodes with the Thermo Scientific™ Orion™ ROSS™ Combination Spear Tip pH Electrode. This electrode provides stable readings to 0.01 pH in less than 30 seconds, even in extreme cases of samples varying from one another by…

The POLILYTE HP pH electrode incorporates the SINGLE PORE™ design and a solid state electrolyte for difficult media, such as very dirty, fatty, oily, partially rganic or ion weak media. There is no diaphragm, so the usual problems with clogged diaphragms do not occur. The EVEREF™-L Labyrinth reference system is used to increase the diffusion distance to 200 mm, which increases sensor life in aggressive media.POLILYTE™ HP 225a-…
