Vaisala Indigo 201 host device for GMP251 and GMP252 carbon dioxide probes

Vaisala has launched a host device for GMP251 and GMP252 carbon dioxide probes. Indigo 201 is a first product in a series of host devices, designed to extend functionalities for the company’s existing and future Indigo-compatible probes. It provides an optional display, analog outputs and relays, and a wireless user interface accessed easily by, eg, a mobile phone.

The currently available Indigo-compatible CO₂ probes, GMP251 and GMP252, are designed for harsh and humid environments. They are used in life science incubators, agriculture, cold storages and demanding HVAC applications, such as swimming halls.

The Indigo 201 uses a wireless user interface for easy configuration: 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 removed and changed to another one. Users can also calibrate the probe with the help of the host device. 

The measurement result can be shown on the display or be converted into other formats, eg, 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 to, eg, turn on/off a fan or giving an alarm.
