Benchtop pH Meter 5500

This Weber Scientific Benchtop pH Meter 5500 offers superior value and performance at an economical price. The large display makes measurements easy to read. The splash-resistant membrane keypad provides easy calibration and operation.

Two point calibration is quick and easy with automatic buffer recognition of two buffer sets (4.01, 7.00,and 10.01; or 4.00, 6.86 and 9.18).The automatic lock mode notifies the user when the reading has stabilized and will hold the reading. Temperature compensation is automatic when either the 3-in-1 probe (included) or a separate ATC probe is used.

Inputs include BNC for electrode, 8-pin DIN for temperature probe, pin plug for reference pH, and AC input. The meter can operate on AC power or batteries.

Key Features

  • Giant LCD with 16mm character size
  • Auto-block mode
  • 3-in-1 probe
  • ~50 hour battery life
