Apera SX736 7-in-1 Portable Handheld pH/DO/Conductivity Meter Kit for Water Quality Analysis

The Apera SX736 is a portable handheld multiparameter meter kit designed for precise laboratory-grade water quality analysis across seven key parameters: pH, dissolved oxygen (DO), conductivity, total dissolved solids (TDS), salinity, and resistivity. This compact instrument is ideal for field applications in environmental monitoring, water treatment, hydroponics, aquaculture, and biotechnology research related to bioprocessing and molecular diagnostics involving aqueous solutions.

Key technical features include:

• Intelligent functions: automatic calibration (1-3 points), temperature compensation, self-diagnosis, data logging (300 sets), and auto power off.
• Digital filter technology: improves response time and measurement accuracy for critical parameters.
• Automatic electrode recognition: switches modes automatically based on connected sensor.
• Robust construction: IP57-rated water resistance for use in harsh environments.

The kit comes complete with:

• 201T-S pH/temp electrode: fast response, 0–14 pH, 0–80°C range, single ceramic junction, 1 m cable, 8-pin connector.
• 3-in-1 polarographic DO electrode: automatic temperature/salinity compensation, 0–20 mg/L range, 2 m cable.
• 2301T-S conductivity electrode: platinum black sensor, 0–200 mS/cm range, integrated temperature sensor.

Calibration is supported by:

• pH buffers (4.00, 7.00, 10.00) included for 1-3 point automatic calibration recognizing five standard points.
• One-point automatic conductivity calibration at 1413 µS/cm.
• DO calibration via saturated oxygen and zero-oxygen standards.

This meter’s versatility and data logging functionality make it essential for molecular cloning workflows, biopharmaceutical production pipelines, and synthetic biology research, while its rugged portability benefits environmental scientists and clinical diagnostics professionals performing on-site fluorescence analysis and live-cell imaging solution assessments. The included rugged carrying case and comprehensive accessory set further enhance its utility in laboratory and field scenarios.
