Key benefits

Designed for remote installations in tight spaces

DMP7 has a short probe length (41 mm / 1.61 inches) that allows it to be used in installations where space is limited. It also comes with a pressure-tight Swagelok® fitting, making it suitable for installations with pressure between 0 ... 10 bar/0 ... 145 psi.

Fast reaction time and stability at low dew points

The Vaisala DRYCAP® sensor is immune to particulate contamination, water condensation, oil vapor, and most chemicals. The sensor is condensation resistant and recovers perfectly if exposed to water. Its fast reaction time and dependable stability give it unmatched performance even in dynamic and low dew point applications.

Use standalone or with an Indigo Transmitter

Its measurement intelligence and digital Modbus RTU over RS-485 connection within the probe mean that the DMP7 can be used as a standalone device. It can also be easily integrated into other systems.

DMP7 is part of the Vaisala Indigo family, so it can be used with Vaisala Indigo series transmitters. The transmitters offer various additional benefits such as a display for data visualization, easy access to probe configuration, and more extensive options for connectivity, supply voltage, and wiring.

Whether using the DMP7 on its own or with an Indigo transmitter, it can be connected to the free Vaisala Insight software for easy field calibration, probe configuration, and device analytics.
