• High Accuracy Dual Measurement：This advanced digital dissolved oxygen meter provides precise measurements of both DO levels (0.0-30.0mg/L) and temperature (0-40°C/32-104°F) with exceptional accuracy (±1.5% F.S for DO, ±0.5°C for temperature). The quick response time (45s) ensures you get reliable results instantly for any liquid testing needs.
• Automatic Temperature Compensation：Featuring smart automatic temperature compensation (0-40°C), our DO meter delivers consistently accurate readings regardless of environmental changes. The stable performance eliminates measurement errors caused by temperature fluctuations, making it ideal for professional water quality analysis.
• Portable Pen Design With Long Electrode：The compact 155mm pen-shaped design with 150mm electrode and 1.15m cable allows for easy on-site testing anywhere. Weighing just 331g with pocket-size dimensions, this lightweight meter comes with 6 replaceable electrode heads for extended use in various field conditions.
• Simple Calibration & User-Friendly：Designed for hassle- operation, our oxygen meter supports both single-point and double-point automatic calibration (null point or air calibration). The clear display shows DO values and temperature simultaneously, while the auto-shutdown feature conserves battery life after 8 minutes of inactivity.
• Versatile Application Scenarios：Great for diverse environments including freshwater/saltwater aquaculture, swimming pools, beverage production, wastewater treatment plants, and laboratory research. The durable ABS construction ensures long-lasting performance in challenging conditions (0-40°C with 90% RH max).
