3505, 3510 and 3520 Bench pH Meters

3505

• General purpose education laboratory pH meter
• Intuitive operation via rotary controls
• pH, temperature and mV mode for redox and electrode diagnosis
• Calibration controls locked during measurement
• Manual or automatic temperature compensation
• Large display
• Battery or mains operated

The 3505 is a simple to use laboratory pH, mV and temperature meter for use in general purpose and educational applications. It utilises rotary controls for mode selection and pH calibration. A novel design feature ensures that inadvertent movement of the calibration controls has no effect during sample measurement. The large display ensures that during demonstrations and when used by groups, all can easily see the clear LCD readout.

3510

• Simultaneous readout of pH and temperature
• pH resolution to 3 decimal places
• 1, 2 or 3 point calibration
• Automatic or manual buffer selection
• Storage of up to 32 results
• RS232 connection to printer or PC via DataWay

The 3510 is a versatile, simple to use pH, mV and temperature meter that is ideal for routine analysis. With up to three decimal place resolution and a choice of up to three calibration points the 3510 provides the user with added flexibility where future demands for enhanced performance may be required. A choice of pH calibration buffers to DIN, JIS and NIST standards can be used for automatic calibration, as well as manually entered buffer values.

3520

• Ideal for quality control and GLP applications
• Up to 3 decimal place resolution
• 1, 2 or 3 point pH calibration
• Automatic or manual buffer selection
• Multiple language options
• Storage of up to 500 results
• RS232 connection to printer or PC or infra red (IrDA) communication
• GLP compliant

The 3520 dynamic pH/mV meter offers research grade specifications with a comprehensive range of features and functions, making it suitable for the broadest range of research, general laboratory, QC and GLP based applications. The built in data logger can store, print or output readings based on a wide range of trigger options, making this model suitable for monitoring and controlling pH levels.
