At Forum Labo from March 28-30, 2017, Vaisala will present Indigo 201, a new host device for the GMP251 and GMP252 carbon dioxide measurement probes. Indigo 201 is the first in a series of host devices designed to extend the functionality of existing and future Indigo compatible probes from Vaisala. The Indigo 201 transmitter is equipped with an optional display, analog outputs and relays as well as a wireless user interface easily accessible from a smartphone, for example. The measurement operations will be greatly facilitated.
The new generation of associated probe, the Vaisala GMP251 probe was designed for laboratories, life science incubators: agriculture, cold rooms; and demanding HVAC applications.
“Today, carbon dioxide is used more and more, for example in refrigeration systems, because it is more environmentally friendly and has a lower impact on global warming than refrigerants such as CFCs , HCFC or HFC, ” explains Maria Uusimaa, product manager at Vaisala. At the same time, it is important to control the CO 2 levels of these systems using reliable measurements in order to ensure personal safety.
A wireless interface for greater flexibility of use
The Indigo 201 transmitter has a wireless user interface for easy setup. This allows users to easily configure the host device from any device with a WLAN connection, such as a laptop or desktop computer, or a mobile phone. A temporary display of measurement data from the Indigo probe is also available wirelessly.
The host device also helps reduce downtime as the probe can be easily removed and replaced with a new one. Users can also calibrate the probe using the Indigo 201 transmitter.
Measurement results can be displayed on the screen, or converted to different formats, such as analog output signals, and for relay activation. These features are useful in various monitoring and control systems, and the relays can even be used to build small-scale systems, for example turning on / off a fan or triggering an alarm.
