Why Our Technology Outperforms Competitors

Our dissolved oxygen and pH meter achieves 0.01 mg/L resolution - 3X sharper than industry averages. The dual-sensor system auto-compensates for temperature (0-50°C) and salinity (0-45 PPT), eliminating 92% of calibration errors reported in 2023 field tests. See how we stack up:

Feature Standard Models Our Pro Series
DO Accuracy ±0.3 mg/L ±0.05 mg/L
Battery Life 48 hours 120 hours

Real-World Success Stories

When Maine's largest lobster hatchery replaced their legacy sensors with our dissolved oxygen meter and sensor combo, hatch rates jumped from 41% to 67% in one season. "The automatic data logging caught oxygen dips we'd never detected before," reported Chief Biologist Emma Wallace.

FAQS on dissolved oxygen and ph meter

Q: What is a dissolved oxygen and pH meter used for?

A: A dissolved oxygen and pH meter is a device that measures both oxygen levels and acidity/alkalinity in water. It is commonly used in aquaculture, environmental monitoring, and laboratories. This dual functionality ensures efficient water quality analysis.

Q: How often should I calibrate a dissolved oxygen meter and sensor?

A: Calibrate your dissolved oxygen meter and sensor before each use or daily for continuous monitoring. Follow manufacturer guidelines using calibration solutions. Proper calibration ensures accurate and reliable readings.

Q: Can a pH and dissolved oxygen meter be used in saltwater environments?

A: Yes, but ensure the device is specifically designed for saltwater applications. Saltwater can corrode sensors not built for such conditions. Always rinse sensors with fresh water after use to prolong lifespan.

Q: What maintenance do dissolved oxygen and pH sensors require?

A: Regularly clean sensors with a soft cloth and appropriate cleaning solutions. Store them in recommended storage solutions to prevent drying. Replace membranes or electrodes as per the manufacturer’s instructions.

Q: Why do my dissolved oxygen meter and pH meter show inconsistent readings?

A: Inconsistent readings may result from dirty sensors, expired calibration, or environmental interference. Check for air bubbles on sensor surfaces and recalibrate. Ensure the water sample is stable and free from contaminants.
