Page 11: Introduction
1. Introduction The SR05, manufactured by Hukseflux Thermal Sensors, is an ISO 9060 second class pyranometer designed for general solar radiation measurements in agricultural and meteorological networks and PV monitoring. Both analogue output and Modbus over RS-485 are supported. 2. Specifications... -

Alternatively, remove the sensor levelling feet to allow it to be mounted directly to the mounting bracket. 2. Secure the solar radiation sensor to the mounting bracket. The blue dots in the following figure indicate the mounting holes used for this pyranometer.

Page 22: Maintenance And Troubleshooting
10. Maintenance and troubleshooting The SR05 has no service items requiring scheduled replacement. There is no accessible desiccant cartridge to maintain. Use pure alcohol or distilled water and a lint-free cloth to clean the dome, removing smears and deposits. Local conditions and application dictate cleaning interval. - Page 24 INFO Global Sales & Support Network A worldwide network to help meet your needs Australia Costa Rica Southeast Asia Garbutt, QLD Australia San Pedro, Costa Rica Bangkok, Thailand Location: Location: Location: 61.7.4401.7700 506.2280.1564 66.2.719.3399 Phone: Phone: Phone: info@campbellsci.com.au info@campbellsci.cc thitipongc@campbellsci.asia Email: Email: Email:...
