Jenway 3520 pH/mV/temperature Meter

This listing is for the Jenway 3520 bench-mounted laboratory pH/mV/temperature meter. The unit is in full working condition and is ready for immediate use. The Jenway 3520 is a bench-mounted laboratory pH/mV/temperature meter designed for precise measurement and recording of hydrogen ion concentration (pH), redox potential (mV), and solution temperature in scientific, QC (quality control) and GLP environments.

Measurement Capabilities

• Measures pH, mV (redox potential) and temperature simultaneously.
• High resolution: up to three decimal places (0.001 pH) for detailed accuracy.
• Wide pH range: typically –2.000 to +20.000 pH units.
• Temperature range from approximately –10 °C to +105 °C.

Calibration & Buffer Recognition

• Supports 1, 2, or 3-point pH calibration for flexible accuracy.
• Automatic or manual buffer selection, compatible with DIN, JIS and NIST standards.

Data & Logging

• Built-in data logger can store up to 500 readings, with options for printing or exporting via interfaces.
• GLP support includes calibration reminders, security-protected user data, and multiple alarm options.

Display & Interface

• Backlit LCD display shows readings clearly.
• Communication via analogue output, RS-232 serial port and optional IrDA (infra-red) printer interface.

Additional Functions

• Multi-language menu options.
• Alarm outputs (audible and open-collector) for set thresholds.
• Option to wall-mount or bench-top install.

Typical What’s Included

Depending on the specific kit or version you buy, the meter often comes with:

• Glass combination pH electrode
• Automatic Temperature Compensation (ATC) probe
• Buffer sachets (pH 4, 7, 10)
• Electrode stand and holder
• Power supply (230 VAC / UK or 120 VAC versions available)

Typical Applications

The 3520 is suited to:

• Routine pH analysis in research and industrial labs
• Quality control and regulatory compliance testing
• Monitoring & logging in process environments
• Scenarios where traceable, high-precision data is needed

If you want detailed user-manual specifications (e.g., calibration procedure, wiring diagrams), I can help find or summarize that too!
