CO₂, Humidity and Temperature Transmitter GMW80 series

The Vaisala Carbon Dioxide (CO2), Humidity and Temperature Transmitter is the most economical way to monitor both indoor air quality (IAQ) and human presence with one sensor. Inadequate ventilation results in elevated CO2 levels, causing drowsiness and decreased productivity. Good indoor air quality can be achieved based on occupancy levels. Energy is saved by minimizing the use of unconditioned outside air. 5-year warranty is valid for instruments purchased in 2021 and beyond.

For accurate and stable HVAC measurements, the wall-mounted Vaisala CARBOCAP® Carbon Dioxide and Temperature Transmitter Series GMW80 provides the best stability and reliability on the market, up to 15 years. These indoor air quality sensors designed for standard, demand-controlled ventilation applications. The GMW80 is ideal for buildings occupied 24/7.|

The CO2 measurement of the GMW80 series is based on a second-generation CARBOCAP® sensor, which uses a novel, microglow light source instead of an incandescent light bulb for a longer trouble-free lifetime. The internal reference in the CO2 sensor guarantees the best stability and operation also in constantly occupied buildings without frequent readjustments. The CARBOCAP® sensors give correct CO2 measurements immediately when powered on as they have a built-in reference measurement. Proper operation can be verified immediately after snapping on the device cover.

The following product models are available: GMW83RP, GMW83DRP, GMW83, GMW83A, GMW83D, GMW84, GMW84S, GMW87 and GMW88.

About GMW80 Series

The Vaisala CO2 Transmitter GMW80 series transmitters are designed to fulfill the needs for CO2 measurements in standard demandcontrolled ventilation applications.
Temperature measurement is included in most GMW80 series transmitters. Combined with humidity measurement, relay, and LED CO2 level indication, GMW80 series provides you the flexibility needed for a variety of projects.
The CARBOCAP sensors measure CO2 accurately immediately when powered on. As they have a built-in reference measurement they do not need a lengthy learning phase before the measured values are correct. Proper operation can be verified immediately after snapping on the device cover.

Easy Installation

With modern buildings often having hundreds of sensors, installation time per unit can be a significant cost factor. Returning to the building site to check sensor operation adds further costs. The GMW80 series transmitters include a number of subtle design features that have been introduced to make installation and commissioning quick and easy.
The pull-out tab makes opening the transmitter faster than before, while also doubling as a quality check slip and holder for the anti-tamper screw. The backplate can be twisted onto premounted screws, and the wiring can be done easily on the clearly marked backplate. The electronics can be snapped on later when the building automation system is commissioned.
For measurements in more demanding conditions (for example, dusty or humid installation locations), the GMW87 and GMW88 models provide an IP64-rated enclosure with a cable gland.

Reliable Operation

Vaisala CO2 Transmitter GMW80 series transmitters are optimized for low maintenance. The unique, low-power CARBOCAP echnology enables a longer lifetime and better stability than ever before. As the power consumption is low, the heat generated by the electronics does not distort the temperature inside the sensor. The internal reference in the CO2 sensor guarantees superior stability and flawless operation even in constantly occupied buildings, without the need for frequent adjustments..
The reliable operation and accurate measurement values of the GMW80 series transmitters contribute to the significant cost savings brought by demand-controlled ventilation.
