720a

Features

  • Dual input channel
  • Automatic Temperature Compensation
  • Adjustable resolution to 0.001 pH
  • pH Autocalibration/Recognition
  • Up to 5 point calibration pH/ISE
  • Direct readout in concentration units
  • Bidirectional RS232 port

With dual electrode inputs, the Model 720Aplus allows two measurements at the same time, perfect for a busy, multi-user laboratory. Measure pH to 0.001 pH units. The pH autocalibration feature recognizes five pH buffers using built-in buffer/temperature tables. Express concentration results to three significant digits. Full five point concentration calibration with automatic blank correction improves results of low level measurements. User prompting walks you through each meter operation. Store data using the internal datalogger or print, via the RS232 with the optional Model 900A printer.

Use with:
8172 pH Probe |  9609 Fluoride Probe  |  Sensolution pH Probe

Most other probes can be used with the meter.
