Smart Compact Humidity and Temperature Probe for rapidly changing environments HMP9

The Vaisala Indigo, Indigo 510, Indigo 520 transmitter has 4 analog channels that can be configured to mA or voltage type and 2 configurable relays. The Vaisala Indigo510 has 2 analog channels. Any of the output parameters from the connected probes can be assigned to control the analog channels and relays. Digital output protocol is Modbus TCP/IP over Ethernet. Besides Modbus TCP/IP, the transmitter's Ethernet connection provides a web interface and cyber-security that meets the modern standards

The touchscreen display provides local data visualization and easy access to probe configuration. The transmitter also extends the options for connectivity, supply voltage and wiring, compared to using just a smart probe. It also provides mechanical support when wall-mount probe installation is preferred.​ Rugged IP66- and NEMA4-rated  metal enclosure ensures reliable performance even in the harshest conditions.

The Indigo-compatible smart probes include humidity probes (HMP1, HMP3, HMP4, HMP5, HMP7, HMP8 and HMP9), dew point probes (DMP5, DMP6, DMP7 and DMP8),  carbon dioxide probes (GMP251 and GMP252), moisture in oil probe (MMP8), temperature probe (TMP1), and vaporized hydrogen peroxide probes (HPP270). The Indigo520 is also compatible with MHT410 Moisture, Hydrogen and Temperature Transmitter for power transformer online monitoring

The Indigo520 dual-probe support allows simultaneous measurements with two Vaisala Indigo-compatible probes for humidity, temperature, dew point temperature, carbon dioxide, vaporized hydrogen peroxide, and moisture in oil measurements. If you need just one probe, the Indigo510 is an ideal choice.
