DO meters

Introduction to DO Meters

A DO meter is a laboratory analytical instrument used to determine the concentration of dissolved oxygen in water and liquid solutions. This instrument plays an essential role in water quality monitoring, biotechnology research, environmental testing, and wastewater treatment facility operations.

When selecting a DO meter, users should consider the appropriate number of measuring channels for their needs, from basic single-channel models to dual-channel models with galvanically isolated inputs to prevent cross-interference during simultaneous measurements. In addition, multi-parameter integration for pH, ORP, conductivity, and turbidity, as well as the application of IDS digital sensor technology, are important criteria to ensure data accuracy. Currently, Hoa Viet distributes genuine benchtop DO meters from WTW (Germany), meeting stringent laboratory analytical standards.

Which brands of DO meters does Hoa Viet supply?

Hoa Viet currently distributes genuine digital DO meters from WTW - Germany, including benchtop models in the inoLab and MultiLab series.

Should you choose a single-channel or dual-independent-channel DO meter?

A single-channel meter is suitable for sequential, individual parameter analysis at a cost-effective investment. Meanwhile, a dual-channel meter with galvanically isolated channels allows simultaneous connection and reading of two sensors without concern for signal interference between electrodes.

What are the advantages of IDS digital sensor technology in DO meters?

IDS digital sensor technology converts measurement signals into digital format right at the sensor head before transmission to the meter, completely eliminating signal loss and noise along the cable. Additionally, IDS sensors can store calibration data and sensor identification information directly in the probe head.

What other parameters can a benchtop DO meter measure in an integrated system?

Depending on the equipment model, multi-parameter meters can support additional measurements for pH, ORP, mV, conductivity, and turbidity when paired with corresponding sensors. Please contact Hoa Viet for consultation on the appropriate electrode configuration for your testing requirements.
