DTR502B solar radiation shield is compatible with the probe heads of HMP3, HMP7, and HMP9 probes. The sensor head support that is included with the DTR502B is suitable for attaching HMP3 and HMP7 probe heads, but for HMP9 you need an alternate sensor head support (item code 215130).
- Mount the solar radiation shield in the measurement location using the provided mounting accessories, screws, and washers. You can mount the radiation shield to a pole mast as shown in Figure 1, or to a horizontal beam directly from its support plate.
Attach the probe head to the sensor head support and secure it with a cable tie. The
alternate sensor head support (item code 215130) needed with HMP9 is shown in Figure 2.
- Insert the fastening ring and the sealing ring on the probe head.
- Slide the probe head into the radiation shield and tighten the sealing ring.
