The Thermo Scientific Orion 261S pH meter is designed for accurate measurement of pH, mV (ORP) and temperature. The 261S pH meter features an intrinsically safe rating for measurement in hazardous and confined space environments and anywhere non-sparking equipment is desired. Waterproof housing makes the Thermo Scientific Orion unit perfect for rugged field applications.

The Thermo Scientific Orion 261S has a pH range of -2.00 to 16.00pH with an accuracy of 0.01pH. The temperature range of the Thermo Scientific Orion 261S is -20°C to 120°C with an accuracy of ±0.3°C. Millivolt readings from ±1300 mV are accurate to 0.1% value + 0.30mV. A large easy-to-read display monitors electrode response condition and calibration status as well as pH, mV and temperature readings. The battery-operated meter is supplied with a built-in quiver and neckstrap.

Thermo Scientific Orion meter and electrode packages contains a rugged, low-maintenance Orion Triode 3-in-1 combination pH Electrode. An optional field kit for the Thermo Scientific Orion 261S is also available, containing a neckstrap, hard case, stand, electrode holder, beakers, 4, 7, 10 buffers, RS232 cable and software.
