Hints on Electrode Maintenance

The first name in ion selective technology offers a variety of choices in microprocessor meters to fit your laboratory applications. These advanced meters are for analyses that require the highest accuracy for pH and ion concentration measurements. All meters include a pH combination electrode and manual. Key features of these Orion ion selective meters are:

• Direct ISE/pH readout
• Simultaneous display of data/temperature
• Manual or automatic temperature compensation
• Temperature: −5 to 105°C, ± 0.1°C accuracy
• 5 point Auto-Buffer recognition/Calibration
• Adjustable isopotential point
• Slope range: 80 to 120% effieciency
• BNC connector
• CE mark of conformance
• Function: pH/ISE/mV/T
• RS232 interface
• Alarm limits, High/Low
• Autobank
• Datalogger 25

With dual electrode inputs, the Orion 720A+ allows two measurements at the same time, perfect for a busy, multi-user laboratory. 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 port.
