Vaisala INDIGO201

The Indigo 201 is an IP65-rated analog output transmitter, a host device for Indigo compatible CO2 probes with display, 4-20 current loop output and two relays. Probes can be connected directly or with a remote cable (available as accessories) to the Indigo 201. User configuration and temporary viewing of data is easy and convenient with a wireless browser-based user interface.

The GMP251 and GMP252 are intelligent probes. They are ideal for measuring carbon dioxide in agriculture, refrigeration, greenhouses and demanding HVAC applications. They are suitable for harsh and humid CO2 measurement environments where stable and accurate CO2 measurements are needed.

These probes are based on Vaisala’s unique, second-generation CARBOCAP® technology that enables exceptional stability. The measurement range is selectable between:

• GMP252: 0 … 2000 and 0 … 20000 ppmCO2
• GMP251: 0 … 2% and 0 … 20%CO2
