Thermo Electron Orion VSTAR90 pH/ISE/Conductivity Meter, 4-Channel

The Thermo Electron Orion VSTAR90 is a high-performance, multi-parameter benchtop meter designed for demanding environmental and industrial testing applications. With its modular 4-channel architecture, this instrument allows you to customize your measurement setup by selecting from five interchangeable modules to suit your specific needs. Whether you are measuring pH, ion concentration, conductivity, dissolved oxygen, or temperature, the VSTAR90 delivers exceptional accuracy and reliability.

Key Features & Highlights

• Modular 4-Channel Design: Choose from five modules to configure up to four channels simultaneously, providing maximum flexibility for multi-parameter testing.
• High Accuracy pH Measurement: Achieve precise pH readings with a range of -2.000 to 20.000, resolution up to 0.001, and accuracy of ±0.002. Calibrate with up to 6 points for enhanced precision.
• Versatile Conductivity Measurement: Measure conductivity from 0.00 to 3000 mS with 0.5% reading accuracy and up to 5 calibration points, suitable for a wide range of sample types.
• ISE and ORP Capabilities: The meter supports ion-selective electrodes (ISE) with concentration ranges in ppm, M, mg/L, %, ppb, or unitless, and ORP measurements with ±0.2 mV accuracy.
• Dissolved Oxygen Options: Compatible with both polarographic and RDO optical probes, offering a wide measurement range and automatic calibration options.
• User-Friendly Interface: Plain language screen prompts, soft keys, and a multilingual interface (English, Spanish, French, Italian, German, Chinese) make it easy for anyone to operate.
• Data Management: Non-volatile memory stores up to 2000 data points with time and date stamps. Transfer data via USB or RS232 ports, and use the included data analysis software for real-time display or post-analysis.
• Convenient Stirring Control: Directly control up to two Orion Star stirrer probes (sold separately) to mix samples without a separate stir plate.
• Robust and Durable: IP54-rated housing protects against splashes, and the included universal power adapter ensures compatibility with almost any AC power source.
• Warranty: Backed by a 3-year meter replacement warranty for peace of mind.

Applications

The Orion VSTAR90 is ideal for environmental testing laboratories, water quality monitoring, industrial process control, and research facilities. It is well-suited for measuring pH, conductivity, dissolved oxygen, and ion concentrations in water, wastewater, soil, and other samples. Its modular design and advanced features make it a valuable tool for professionals who require accurate and reliable measurements in a variety of settings.
