• Customize up to 4 inputs to meet all of your lab's needs
• Program the graphic display to view exactly what you want
• Plain language screen prompts for ease of use

Easily design your own custom meter! Advanced Versa Star Pro meters feature 4 channels to create the meter you need now, and let you change or add modules in the future as your lab's needs change. Includes pH/ISE, DO/RDO and Conductivity modules. Assign the two built-in stirrer probe ports to specific channels to control sample stirring while you measure.

The color graphic LCD display lets you select just the information you want to see. View readings from all the channels at once, or select one channel (parameter). Display readings, connections, time, date, sample ID, user ID, calibration data, or any combination of these. Password protection secures select meter functions, while leaving others accessible to all users. Additional features include adjustable display brightness, intuitive button layout and plain language screen prompts in your choice of six languages.

Calibrate pH using 1 to 5 buffers with NIST and DIN buffer recognition, or up to 6 points with your own custom values. Calibrate DO using water-saturated air, air-saturated water or a Winkler titration to meet your procedural requirements. Automatic temperature compensation, automatic/ manual barometric pressure compensation, and manual salinity input produce accurate measurements. Calibration date, values and slopes are stored in the Calibration Log for later review.

Choose from three measuring modes: Continuous mode, AUTO-READ™ mode that locks in the stable reading on your screen, or Timed mode that displays a measurement at timed intervals. Log and download up to 2,000 data points including time and date stamp, sample ID and user ID to your computer or printer using RS-232 or USB. Selectable visual and audible alarms alert you to readings outside your set points. The IP54-rated housing handles splashes, and can be wall-mounted.
