edge® measures pH, conductivity and dissolved oxygen through its unique digital electrodes.These digital electrodes are auto-recognized, providing sensor type, calibration data and a serial number when connected to edge by an easy to plug-in 3.5mm connector.


  • Simply connect each probe via the 3.5 mm jack, Digital Smart Electrodes are automatically recognized
  • Resolution selectable from 0.01 and 0.001 pH
  • Range -2.000 to 16.000 pH
  • Accuracy ±0.002 pH for 0.001 pH resolution; ±0.01 for 0.01 resolution
  • Data logging
    • Manual log-on-demand
    • Manual log-on-stability
    • Interval logging
  • Temperature readout (°C or °F)
  • Automatic Temperature Compensation (ATC)
  • CAL Check™ Indicators
    • Probe condition
    • Response time
    • Check buffer
    • Clean electrode
  • Sensor Check™ Indicators
    • Broken electrode
    • Clogged junction
  • GLP data
    • Records date, time, offset, slope and buffers used during calibration
  • Five-point calibration
    • A choice of seven pre-programmed buffers plus two selectable custom buffers
  • Calibration tag on screen
    • Identifies buffers used for current calibration
  • Calibration expiration warning

Portable field unit

edge® is ideal for field use due to its light weight, large screen, and thin design. It can easily be slipped into a backpack or messenger bag. The battery life lasts up to 8 hours when used as a portable device.

Wall-mount cradle

The included wall-mount cradle makes it easy to conserve space on the benchtop while also charging edge with the AC adapter. The cradle is ideal for continuous monitoring applications.

Electrode holder with built-in cradle

The electrode holder features a swivel adjustable arm with a built-in cradle to hold edge securely in place at the optimum viewing angle.

Sleek design

Incredibly thin and lightweight, edge measures just 1/2” (12 mm) thick and weighs just 8.8 ounces (250 g).
