Orion Ross pH Electrodes

Thermo Orion Ross pH Electrodes have a virtually drift-free reference with optimum stability, even in samples varying in temperature. Unmatched two-year warranty on all six styles. Compatible with Tris buffers.

ROSS Ultra™ Triode electrodes offer all of the benefits of a traditional ROSS electrode with the added benefit of a built-in temperature sensor—measure pH, mV, and temperature all in one electrode! Available in both a refillable and gel version.

ROSS™ combination electrodes, with a unique internal reference system developed by Orion, offer greater accuracy, reproducibility, stability, and faster response times than any other standard electrode line. ROSS electrodes minimize drift, even in samples that vary in temperature. Compatible with Tris buffers.

All ROSS electrodes listed have a pH measurement range between 0 and 14, a temperature range between 0°C–100°C (0°C–80°C for 3808-76), and a ROSS internal reference.

Recommended Use:

3802-55: pH of soft, moist surfaces both solid and semi-solid such as agar gel plates, meats, bread dough and similar samples. Small samples in micro sample dishes.

3802-60: May be used intermittently in some organics. Polar organic compounds sound be strictly avoided. Field pH measurement where stability and high performance is desired, on-site soil pH

Key Features

• Uses ROSS technology for greater stability, reproducibility, stability, and faster response times
• Less drift over time means less recalibrating
• Compatible with Tris buffers
• Available in glass or epoxy bodies: ceramic, glass fiber, or sure-flow junctions
