•	Feature-packed for accurate, reliable measurements
•	Logs with time/date stamps support GLP compliance

At just 6-1/8"W x 7-7/8"L x 2-1/2"H, these budget-friendly meters save valuable bench space. The 5" backlit display makes viewing pH, mV, temperature, slope and status icons easy. The durable membrane keypad supports heavy lab use and disinfection requirements. IP54-rated housing protects meter against spills, splashes and dust intrusion.

These meters offer features typically found only on more expensive units. Calibrate with USA or DIN pH buffers using 1 to 5 points. ORP and temperature are calibrated at one point. Choose from continuous measurement, auto-read and timed measurements. Onscreen stabilizing and ready indicators identify when measurements are complete.

View active pH, ORP and temperature calibration logs with date/time stamp to ensure accurate, reproducible measurements. Record key measurements using the 500-point data log with date/time stamp. For long-term storage, output data and calibration logs to a printer or computer.

Meter only includes: electrode stand, PC cable, universal power adapter and meter. Standard meter kit also includes: 60 mL each of pH 4.01, 7.00 and 10.01 buffers and 9157BNMD pH electrode. Difficult sample meter kit also includes: 60 mL each of pH 4.01, 7.00 and 10.01 buffers, 927007MD stainless steel ATC temperature probe and 9165BNWP pH electrode. 3-year meter warranty.
