What is the typical accuracy for pH measurements on this type of meter?

For this class of bench-mounted meter, pH accuracy is typically around ±0.002 pH, with a resolution often up to 0.001 pH.

Are pH electrodes and temperature probes usually included with a used unit?

While the meter itself is listed, probes are often sold separately or may need replacing due to wear. Buyers should confirm with the seller what specific accessories are included.

Can this meter be used for GLP (Good Laboratory Practice) environments?

Yes, units of this type often include features such as calibration reminders, security-protected user data, and alarm options, which are beneficial for GLP compliance.

What kind of maintenance does a pH conductivity meter require?

Routine maintenance typically involves regular calibration with certified buffer solutions, cleaning of electrodes, and ensuring proper storage of probes when not in use.

Is this unit suitable for field use?

This is a bench-mounted laboratory unit, designed for stable laboratory environments. For field use, a portable or handheld meter would typically be more appropriate.

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.

Key Features

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!
