Thermo Scientific Orion Field Meters

Thermo Scientific Orion Field Meters are portable waterproof water quality instruments that measure pH, conductivity, and dissolved oxygen in the field. A complete line of Orion electrodes, buffers, solutions and accessories for these meters are available from Geotech.
Thermo Scientific Orion Model 261S

Thermo Scientific Orion
Model 261S pH/mV/Temperature Meter

The Model 261S was designed for accurate measurement of pH, mV and temperature in the field. The Model 261S is rated as intrinsically safe for measurement in hazardous and confined space environments and anywhere non-sparking equipment is desired. A large easy-to-read display monitors electrode response conditions and calibration status as well as pH, mV and temperature readings. The battery-operated meter is supplied with a built-in quiver and neckstrap. The meter and electrode package contains a rugged, low-maintenance Orion Triode 3-in-1 combination pH electrode.

  • Waterproof and intrinsically safe
  • 2 point autocalibration with choice of buffers
  • Designed for field use
  • Optional RS 232 interface and software

Thermo Scientific Orion Model 131S

Thermo Scientific Orion Model 131S Waterproof Conductivity/TDS/Salinity/ Temperature Meter

The Model 131S is designed for measurement of conductivity, salinity, total dissolved solids and temperature. Wide measurement range allows for a variety of samples. The meter calibrates via cell constant adjustment method. The meter is compatible with two or four electrode cells. Temperature compensation options, such as automatic or manual linear function, and nonlinear function for ultrapure or natural water are available. This meter offers an easy-to-use interface and GLP features such as cell status and self-diagnostic testing. The Model 131S is intrinsically safe for use in a non-sparking environment. Complete field kit available.

  • Intrinsically safe (explosion proof)
  • Compatible with USP regulations
  • Wide cell constant range for maximum compatibility
  • Optional RS 232 interface and software
