It delivers an accuracy of ±0.002 pH ±1 digit and includes a Swiss-made LabSen® 211 combination pH electrode featuring an impact-resistant, bubble-free sensor tip and a long-life reference system. A dedicated MP500 temperature probe enables simultaneous pH and temperature measurement. The meter supports automatic 1–5-point calibration, electrode-condition diagnostics, and calibration reminders to help maintain measurement reliability. Its Good Laboratory Practice (GLP) data-management system stores up to 500 timestamped measurement records, which can be exported through USB for spreadsheet analysis and quality-control documentation. An ORP measurement mode is also available with a compatible electrode sold separately.\u003c\/p\u003e\n\n\n\u003cp\u003e• Product Type: High-precision benchtop pH meter kit\u003cbr\u003e\n• Brand: Apera Instruments\u003cbr\u003e\n• Model: PH820\u003cbr\u003e\n• SKU: AI531\u003cbr\u003e\n• pH Measurement Range: −2.00 to 16.00 pH\u003cbr\u003e\n• pH Accuracy: ±0.002 pH ±1 digit\u003cbr\u003e\n• pH Resolution: 0.001 pH\u003cbr\u003e\n• Included pH Electrode: Swiss-made LabSen® 211 combination pH electrode\u003cbr\u003e\n• Electrode Design: Impact-resistant, bubble-free sensor tip designed to minimize air-bubble interference\u003cbr\u003e\n• Reference System: Long-life reference system designed to support stable measurements\u003cbr\u003e\n• TRIS Buffer Compatibility: Compatible with TRIS buffer for specialized biological assays\u003cbr\u003e\n• Temperature Probe: Dedicated MP500 temperature probe\u003cbr\u003e\n• Calibration: Automatic 1–5-point calibration\u003cbr\u003e\n• Supported Calibration Buffers: pH 1.68, 4.00, 7.00, 10.01, and 12.45\u003cbr\u003e\n• Electrode Diagnostics: Monitors electrode slope and displays electrode-condition information\u003cbr\u003e\n• Calibration Reminders: Prompts users when recalibration is due\u003cbr\u003e\n• Data Storage: Up to 500 GLP measurement records, including date, time, measurement value, unit, and temperature\u003cbr\u003e\n• Data Export: USB connectivity for exporting stored measurement data to a connected PC\u003cbr\u003e\n• ORP Measurement: Supported with a compatible ORP electrode, sold separately\u003cbr\u003e\n• Display: Large backlit LCD with simultaneous pH and temperature readings, stability indicators, and calibration-status information\u003cbr\u003e\n• Ingress Protection: IP54 — resistant to dust and water splashes; not suitable for immersion\u003cbr\u003e\n• Power Supply: Included DC 9V power adapter\u003cbr\u003e\n• Connectivity Ports: pH\/mV, reference (REF), temperature (TEMP), RS232, and DC 9V input\u003cbr\u003e\n• Primary Applications: Nutrient-solution testing, irrigation-water analysis, laboratory pH measurement, and production quality control\u003cbr\u003e\n• Cultivation Applications: Nutrient mixing stations, reservoir checks, coco and rockwool cultivation, recirculating hydroponics, and incoming-water verification\u003cbr\u003e\n• Quality-Control Documentation: GLP records support traceable nutrient-batch testing and water-quality monitoring\u003cbr\u003e\n• Manufacturing Quality System: Apera products are manufactured under an ISO 9001:2015-certified quality system.\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The Apera PH820 combines exceptional ±0.002 pH accuracy with GLP data storage for up to 500 measurement records and USB data export.
