FAQs

1. What makes the It Portable Dissolved Oxygen Analyzer suitable for field use?

The It is designed as a lightweight, compact, and easy-to-carry device, making it perfect for on-site applications. It comes with one-hand operation, low power consumption, and runs on AA or rechargeable batteries, allowing long hours of field testing without frequent recharging. Its rugged design ensures reliable performance even in outdoor environments such as rivers, lakes, and wastewater treatment sites.

2. How accurate is the It Portable Dissolved Oxygen Analyzer in measuring dissolved oxygen?

The It provides precise readings with a measuring range of 0.00 to 20.0 mg/L and 0.0 to 200% saturation. It has a high-resolution of 0.01/0.1 mg/L or 0.1%/1% () and an error margin of only ±0.5% FS. This makes it highly reliable for detecting both very low and very high oxygen levels in water samples, which is essential for accurate water quality monitoring in laboratories, environmental studies, and industrial processes.

3. What types of calibration does the It Portable Dissolved Oxygen Analyzer support?

The It supports up to two-point calibration, which includes calibration with water vapor-saturated air and a zero-oxygen solution. This ensures that the analyzer delivers stable and accurate readings under varying environmental conditions. With this calibration system, users can trust the analyzer for both routine and advanced testing requirements.

4. Can the It Portable Dissolved Oxygen Analyzer store data for later use?

Yes, the It is equipped with data storage capability. It can store calibration data along with up to 99 groups of measurement data. This is particularly useful for field researchers and environmental scientists who need to collect multiple samples in different locations. Stored data can later be reviewed, reducing the need for manual note-taking and ensuring accuracy in record-keeping.

5. In which industries and applications can the It Portable Dissolved Oxygen Analyzer be used?

The It is a versatile analyzer widely used across industries that require monitoring of dissolved oxygen. It is ideal for on-site water analysis, wastewater treatment plants, aquaculture, environmental monitoring, and laboratory research.
