ISO-17025 accredited pyranometer calibration services
ISO-CAL North America LLC is a full service ISO-17025 accredited calibration laboratory, specialized in solar radiometer (sensor) calibration services. Based in Phoenix AZ, services include indoor and outdoor WRR traceable pyranometer and pyrheliometer calibration
in accordance with the latest ASTM and ISO calibration standards. The ASTM G207-11 indoor secondary transfer calibration method employed by ISO-CAL North America replicates the OEM production calibration of the leading pyranometer manufacturers, assuring continuity in sensitivity scale from one calibration interval to the next. In addition to instrument sensitivity, every ISO-CAL North America calibration report states the expanded calibration uncertainty with a 95% confidence interval (U95). Calibration turnaround times are 1 to 2 weeks typical. Expedited calibration services are also available on request. ISO-CAL North America supports numerous utility scale O&M services providers throughout the solar energy industry, while also tracking the calibration due dates and generating calibration notices to site asset managers via email.

High performing data availability
The SR30-D1 Spectrally Flat Class-A digital pyranometer features an internal maintenance-free heated ventilation system. The circulation of heated air flow between the inner and outer domes suppresses the formation of dew and frost on the pyranometer optic. With < 2.3W max power consumption, SR30 delivers a high level of performance
and data availability. Critical sensor
data, including irradiance, sensor
serial number, and calibration data
are all available via RS485 RTU /
Modbus connection. The sealed desiccant cartridge design with internal ventilation translates into reduced sensor maintenance and cost of ownership.
