Thermo Scientific Orion Lab Star Bench Meters are well suited for academic, water, wastewater and other laboratories seeking a lightweight and easy-to-use instrument for electrochemistry testing. Combined with Thermo Scientific Orion electrodes and solutions, Orion Lab Star Meters offer an economical option for testing and measuring pH, conductivity and dissolved oxygen parameters.

• Budget-friendly DO meter for simplified dissolved oxygen as percent saturation or concentration testing
• Display shows dissolved oxygen, barometric pressure, temperature, and salinity simultaneously for accurate data recording
• Measure 0.0 to 300.0 % saturation, 0.00 to 30.0 mg/L or ppm, and -5.0 to 105.0 °C or 23.0 to 221.0 °F to ensure comprehensive measurement capabilities

• Perform 100% and 0% saturation calibrations, one point concentration calibration using a custom value (Winkler), and one point temperature adjustment calibrations for proficient SOP compliance
• Use automatic barometric pressure compensation for DO measurements with manual value entry in mmHg or bar
• Use automatic salinity compensation for DO measurements with value manual entry of 0.0 to 50.0 ppt
• Large 5-inch backlit display makes viewing and recording measurements easy
• Small meter footprint saves valuable bench space in your lab
• Onscreen stabilizing and ready indicators help identify when readings are complete
• Date and time data stamped data and calibration logs support GLP compliance
• View active DO and temperature calibration logs with date and time stamp to ensure accurate, reproducible measurements
• Use a 500-point data log with date and time stamp to record key measurements
• Output data and calibration logs to a printer or computer for long-term data storage
