Apera SX751 Portable 8-in-1 Multi-Parameter Water Quality Meter Kit

The Apera SX751 is a precision portable multi-parameter water quality meter kit designed for field and laboratory measurements in environmental monitoring, water treatment, aquaculture, hydroponics, and beverage quality control. This compact 8-in-1 instrument accurately measures critical water parameters including:

• pH (range 0–14, temperature range 0–80°C) with a fast-response 201T-S electrode featuring a 30K thermistor temperature sensor
• Dissolved Oxygen (DO) from 0 to 20.00 mg/L using an advanced 3-in-1 polarographic DO electrode with automatic temperature and salinity compensation and reduced polarization time (5 minutes)
• Oxidation-Reduction Potential (ORP) ranging from -1999 to 1999 mV via the 301Pt-S platinum ring sensor for stable redox potential measurement
• Conductivity spanning 0 to 200 mS/cm (0–200,000 µS/cm) using a platinum black 2301T-S sensor with automatic temperature compensation
• Total Dissolved Solids (TDS), salinity, resistivity, and temperature monitoring integrated with comprehensive data logging capability (up to 400 datasets)

Key technical features include:

• *Automatic calibration* with 1-3 point pH calibration recognizing standard buffers (1.68, 4.00, 7.00, 9.18, 12.45), conductivity one-point calibration at 1413 µS/cm
• *Digital filter technology* improving response time and measurement precision, essential for reliable biotechnology and molecular diagnostics workflows
• *Automatic electrode recognition* for seamless parameter switching, aiding efficient bioprocessing and synthetic biology research applications
• Ruggedized *IP57 water-resistant casing* suitable for harsh environments encountered in biopharmaceutical production pipelines and environmental water assessment
• Complete kit setup including electrodes, buffers, and carrying case designed for field-ready live-cell imaging medium quality control and clinical diagnostics water analysis

The SX751 meter is widely used by biotechnology specialists, environmental scientists, and clinical professionals requiring dependable, multi-parameter water quality instrumentation critical for gene editing experiments, cell imaging media validation, and biomanufacturing process monitoring. This tool supports complex molecular biology workflows by ensuring optimal solution conditions with precise, integrated parameter analysis.
