FieldNew [Domestic Brand] Portable Dissolved Oxygen Meter

【Visualize Dissolved Oxygen】Measure dissolved oxygen concentration (0.0-40.0 mg/L), dissolved oxygen saturation (0.0-300.0%), and temperature (0.1-40.0°C) with a single device. Useful for understanding oxygen deficiency risks and daily water quality management in aquarium maintenance, aquaculture, field surveys, hydroponics, and more.

【Supports Two Calibration Methods】In addition to the basic air span calibration, it also supports zero calibration, which is effective when you want to measure low concentration ranges (目安: 1 mg/L or less) more accurately. Designed for easy checks before and after measurement, as well as regular management. *Zero calibration is performed at shipment, so it is not necessary for normal measurements. / Zero calibration reagents are sold separately.

【Consumable Parts Replacement = Designed for Long-Term Use】Electrolyte solution and membrane caps are consumables and can be replaced approximately every 3-6 months. Even if measurement values are unstable or calibration fails, the device can be restored through replacement and maintenance, making it suitable for long-term operation.

【IP67 Waterproof & Temperature Compensation】IP67 waterproof for easy use in the field. The temperature compensation function automatically corrects within the range of 0-40°C, supporting stable measurements. *Although waterproof, avoid submerging or prolonged immersion in water.

【Support from a Japanese Brand & Warranty Included】Comes with a warranty. Warranty period: 1 year for the main unit / 180 days for the sensor. In case of any defects, our customer support center will assist you. Additionally, with a 2-sided A3 color easy-to-follow manual and video tutorials, you can use it with confidence even if it's your first time.
