{"product_id":"apera-sx716-portable-do-meter-kit","title":"Apera SX716 Portable DO Meter Kit","description":"\u003cp\u003eThe Apera SX716 (AI461) is a portable, laboratory-grade dissolved oxygen (DO) meter designed for accurate, on-site water-quality monitoring in commercial cultivation, aquaculture, and water-treatment environments. It measures dissolved oxygen concentration in mg\/L (ppm) and percentage saturation simultaneously, alongside solution temperature. The instrument uses Apera's DO500 polarographic electrode, which integrates oxygen, temperature, and salinity sensors into a single probe connected by a 2-meter cable. The electrode requires approximately five minutes of polarization before measurement and reaches 90% of a stable reading within 30 seconds of immersion. Automatic temperature and salinity compensation help maintain measurement accuracy, while manual barometric pressure compensation allows adjustment for elevation. Its IP57-rated enclosure, 100-set data logger, and rugged carrying case make it suitable for routine dissolved oxygen checks in hydroponic reservoirs, recirculating deep-water culture (RDWC) systems, and other water-management applications.\u003c\/p\u003e\n\n\n\u003cp\u003e• Product Type: Handheld dissolved oxygen meter kit\u003cbr\u003e\n• Brand: Apera Instruments\u003cbr\u003e\n• Model: SX716\u003cbr\u003e\n• SKU: AI461\u003cbr\u003e\n• Measurement Parameters: Dissolved oxygen (DO), percentage saturation, and temperature\u003cbr\u003e\n• DO Measurement Range: 0–19.99 mg\/L (ppm) \/ 0–200.0% saturation\u003cbr\u003e\n• DO Accuracy: ±0.3 mg\/L\u003cbr\u003e\n• Electrode Type: DO500 polarographic electrode with integrated temperature and salinity sensors\u003cbr\u003e\n• Electrode Cable Length: 2 m (approximately 6.6 ft)\u003cbr\u003e\n• Electrode Polarization Time: Approximately 5 minutes before measurement\u003cbr\u003e\n• Response Time: Reaches 90% of a stable reading within approximately 30 seconds of probe immersion\u003cbr\u003e\n• Temperature Compensation: Automatic, 0–45°C\u003cbr\u003e\n• Salinity Compensation: Automatic, 0–45 ppt\u003cbr\u003e\n• Barometric Pressure Compensation: Manual adjustment, 66–200 kPa\u003cbr\u003e\n• Calibration: Two-point calibration using air-saturated water and a zero-oxygen sodium sulfite solution\u003cbr\u003e\n• Measurement Stability: LCD stability indicator identifies when readings have settled\u003cbr\u003e\n• Signal Processing: Digital filtering helps reduce noise and improve response in moving or aerated water\u003cbr\u003e\n• Data Storage: Up to 100 measurement records\u003cbr\u003e\n• Stored Information: Reading value, unit, temperature, and serial number\u003cbr\u003e\n• Data Recall: Stored measurements can be reviewed directly on the meter\u003cbr\u003e\n• Water and Dust Protection: IP57-rated enclosure, designed for dust-tight protection and temporary submersion\u003cbr\u003e\n• Power Supply: Two AA batteries\u003cbr\u003e\n• Power-Saving Feature: Automatic shutoff\u003cbr\u003e\n• Primary Applications: Dissolved oxygen monitoring, water-quality testing, aquaculture, and water-treatment operations\u003cbr\u003e\n• Cultivation Applications: Hydroponic reservoirs, RDWC systems, aerated nutrient solutions, and root-zone oxygen monitoring\u003cbr\u003e\n• Included Components: SX716 meter, DO500 polarographic electrode with 2 m cable, calibration and storage sleeve, three replacement membrane caps, electrode inner-solution refill, two AA batteries, membrane-service screwdriver, user manual, and hard-shell carrying case\u003cbr\u003e\n• Replacement Consumables: Replaceable membrane caps and electrode inner solution\u003cbr\u003e\n• Electrode Warranty: 6 months\u003cbr\u003e\n• Meter Warranty: 3 years\u003cbr\u003e\n• Certifications: CE and CMC certification\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The Apera SX716 combines portable dissolved oxygen measurement with automatic temperature and salinity compensation, allowing operators to check oxygen levels directly at reservoirs and water-treatment points.
