Duct Installation Kit (Vaisala item ASM214055) is designed to support the probe head of a HMP9 Humidity and Temperature Probe in installations to ducts and chambers. The kit is lightweight and can be installed with minimal tools.
The kit does not include an attachment for the probe body of HMP9. To mount the probe body, use the probe holder supplied with HMP9, or attach it directly to a compatible Indigo transmitter.
