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.

LSTAR1110 is the pH meter and stand option, which allows you to purchase your pH electrode separately

LSTAR1115 is the standard pH meter kit option, for common pH samples such as drinking water, tap water, buffers (non-TRIS) and general-purpose student use

LSTAR1116 is the easy-to-clean bio pH meter kit option, for pH samples containing TRIS buffers, proteins, sulfides, halides, or other components that can interfere with silver-chloride; included refillable pH electrode is easy-to-clean and restore

LSTAR1117 is the low-maintenance bio pH meter kit option, for pH samples containing TRIS buffers, proteins, sulfides, halides, or other components that can interfere with silver-chloride; included gel-filled pH electrode is low-maintenance and easy to operate

LSTAR1118 is the difficult sample pH meter kit option, for pH samples that are thick, viscous, or semi-solid including foods, beverages, wastewaters, emulsions, soils, slurries, suspended solids or sludges

• Budget-friendly pH meter for simplified pH and ORP testing
• Display shows pH, mV, and temperature simultaneously for accurate data recording
• Measure -2.000 to 18.000 pH, -2000.0 to +2000.0 mV and -5.0 to 105.0 °C or 23.0 to 221.0 °F to ensure comprehensive measurement capabilities
• Perform one-to-five-point pH calibrations, one-point ORP calibrations and one point temperature adjustment calibrations for proficient SOP compliance
