Vaisala launches a new host device for carbon dioxide probes

Published: 30-Jan-2017

The Finnish environmental and industrial measurement company's new device fits their GMP251 and GMP252 probes

Indigo 201 provides an optional display, analog outputs and relays and a wireless user interface for accessibility via mobile devices.

It is a first product in a series of host devices, designed to extend functionalities for existing and future Indigo-compatible CO2probes.

The currently available probes, GMP251 and GMP252, are designed for harsh and humid environments. They are used in life science incubators, agriculture, cold storages, and in demanding HVAC applications, such as swimming halls.

"Today, carbon dioxide is more and more often used, for example, in refrigeration systems, because it is more environmental friendly and has a lower impact on global warming than the restricted CFC, HCFC and HFC refrigerants," said Maria Uusimaa, Product Manager at Vaisala.

These systems must also monitor CO2 levels with reliable measurements for human safety. The Indigo 201 uses a wireless user interface. Users can configure the host using any device with a WLAN connection, such as a laptop, computer or a mobile phone. Temporary viewing of measurement data of the attached Indigo compatible probe can be done wirelessly.

The host allows for minimal downtime as the probe can be easily removed and changed to a new one. Users can calibrate the probe with the help of Indigo 201.

The measurement result can be shown on the display, or be converted into other formats, for example, analog output signals and for relay activation. These features are useful in various control and monitoring systems, . The relays can be used even to build small scale system , for example, to turn a fan on or off, or setting up an alarm.
