Orion is an American developer and manufacturer of electrochemical analytical instruments, now part of the Thermo Fisher Scientific's Water Analysis division. It is commonly referred to as Thermo Scientific Orion. Its predecessor, founded in 1956 as Thermo Electron Corporation, is why some also call Orion Thermo Orion.
Representative Products: pH Meters, Ion Concentration Meters, Conductivity Meters, Dissolved Oxygen Meters, COD Meters, Colorimetric Water Quality Analyzers, Rapid Acid-Base Titration Instruments, Fully Automatic Potentiometric Titration Instruments, Kjeldahl Water Analyzers, Online Water Quality Monitors (Sodium, Chlorine, Fluorine, Calcium, Dissolved Oxygen, Silicon, pH, Conductivity sensors, etc.), Gas Chromatography Accelerators, Micro/Super Micro Balances, Incubators, Automatic Samplers, etc.
For over 40 years, Orolong has been committed to the research and development of electrochemical sensors. To date, Orolong has developed nearly 30 types of ion-selective electrodes, achieving a leap in rapid, simple, and accurate ion-selective electrode measurement methods for ion concentration. Simultaneously, Orolong's online water quality monitors, known for their superior stability and lower detection limits, have become the leading choice in the industry and the forefront in the power sector.
Feature Highlights
The operation interface offers 6 languages for selection, including Chinese and English.
AUTO-READTM feature locks the reading and displays an indicator icon when the data is stable. The timed reading function automatically records readings at the set interval.
Temperature calibration and automatic compensation ensure the measurement accuracy is unaffected by temperature on electrode slope, making the measurement results more reliable.
Built-in salinity curve for seawater.
During TDS measurement, you can select either linear or ISO/EN 27888 curve.
Up to 2,000 sets of measurement data can be saved, in compliance with GLP standards.
Available for data transfer or instrument software updates via USB or RS232 interface with the included data analysis software.
Both desktop and portable instruments can operate with AA batteries or a power adapter.
Desktop protection level IP54, portable protection level IP67.
