Vaisala Introduces a New Series of Host Devices with Indigo 201

Vaisala launches a new 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 existing and future Vaisala's Indigo compatible probes. Indigo 201 provides an optional display, analog outputs and relays, and a wireless user interface accessed easily by, for example, 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 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," says Maria Uusimaa, Product Manager at Vaisala. At the same time it is important in these systems to monitor the CO2 levels with reliable measurements for human safety. 

Wireless Interface Offers Ease of Use

The Indigo 201 uses a wireless user interface for easy configuration:  Users can easily configure the host using any device with a WLAN connection, such as a laptop, computer or a mobile phone. Also temporary viewing of measurement data of the attached Indigo compatible probe can be done wirelessly. 

The host also allows for minimal downtime as the probe can be easily removed and changed to a new one. Users can also 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, and the relays can be used even to build small scale system to e.g. turn on/off a fan or giving an alarm.
