Used Conductivity Meter for sale (3,619)

Condition: used, 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 Gtedpeyk Evqjfx Ahyjw 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!
