Instrumentation

ABB Gas Analyzers are advanced instruments designed for precise measurement and monitoring of gases in industrial processes, environmental applications, and emission control. With innovative technologies such as infrared (NDIR), paramagnetic, zirconia, and tunable diode laser spectroscopy (TDLS), ABB analyzers provide highly accurate and reliable results. They are widely used in power plants, chemical industries, refineries, cement plants, steel industries, and environmental monitoring stations to ensure process efficiency, regulatory compliance, and workplace safety.Key Features

• High Measurement Accuracy – Delivers precise gas concentration readings in real-time.

• Multi-Gas Capability – Capable of analyzing O₂, CO, CO₂, NOx, SO₂, NH₃, CH₄, and more.

• Advanced Detection Technologies – Uses NDIR, zirconia, paramagnetic, or laser-based sensors depending on application.

• Continuous Monitoring – Designed for online, 24/7 process and emission monitoring.

• Rugged & Durable Design – Built to perform reliably in harsh industrial environments.

• User-Friendly Interface – Equipped with digital displays, touchscreen control, and easy calibration.

• Low Maintenance – Long-life sensors with automated self-check functions.

VT - 550 is a micro-controller based instrument which shows real time O2 values. The instrument has an internal battery operated pump to draw in a gas sample for measurement. Typical applications include incubator testing, Food safety, green-house assessment, warehouse monitoring, Con ned Space, Nitrogen Plant etc.
