• Laboratory accuracy everywhere you need it
• Onscreen prompts for quick, easy setup
• Waterproof IP67-rated housing

Get laboratory accuracy in a waterproof portable housing! Meters feature high-end features such as stability and averaging ensure accurate readings. The backlit display lets you view parameter and temperature, plus electrode status, time, date, sample ID, sample date and calibration points. Simple button layout and onscreen messages allow quick meter calibration and set up. Plain-language screen prompts are available in six languages.

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. Calibrate pH using 1 to 5 buffers with NIST and DIN buffer recognition. The Calibration Edit feature lets you fix calibration errors without a complete recalibration.

Log up to 5,000 data points including time and date stamp. Easily transfer data or update software using RS-232 or USB connection and the included data analysis software. Adjustable alarms remind you to calibrate your meter after a set time period, or alert you to measurements outside your set points.
