Jenway 3520

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.
