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
