Key Benefits

Easy Installation

The GMW90 Series Transmitters have been designed for quick and easy installation. Every model includes a display for easy startup. To protect the sensor from dust and dirt during construction and installation, the units can be cabled with back-plate only. Electronics can be snapped on later at an appropriate phase in the construction project. This saves installation time in the project.

Convenient Calibration

Regular instrument maintenance guarantees a long product lifetime although the transmitter’s inspection interval is five years. Calibration is easiest using the exchangeable measurement modules. Sensor traceability and measurement quality is easily maintained by snapping on a new module calibrated at Vaisala factory. The instrument can also be calibrated using a hand-held meter or reference gas CO2 bottle. The service interfaces are easy to reach by simply sliding the cover down. The closed cover keeps the measurement environment stable during calibration and ensures a top-quality final result.
