Pyrgeometers

Apogee Instruments offers both upward- and downward-looking pyrgeometers
Accurate and stable incoming and outgoing longwave radiation measurements
Apogee Instruments’ thermopile pyrgeometers are accurate, stable, durable, and cost effective
Accurate Stable Measurements
Calibration in controlled laboratory conditions is traceable to the World Infrared Standard Group in Davos, Switzerland. Long-term non-stability determined from multiple replicate pyrgeometers in accelerated aging tests and field conditions is less than 2 % per year.
Rugged, Self-cleaning Housing
The patented domed shaped sensor head for the upward-looking model facilitates runoff of dew and rain to keep sensor clean and minimize errors caused by dust blocking the radiation path. Sensors are housed in a rugged anodized aluminum body and electronics are fully potted.
Unique Design
Designed to optimize performance and price. The filter, blackbody thermopile detector, and thermistor (to measure detector temperature) are all contained in a compact housing that provides improved thermal coupling.
On-board Heater
A 0.2 W heater keeps water (liquid and frozen) off the sensor and minimizes errors caused by dew, frost, rain, and snow blocking the radiation path.
SL-510 upward-looking pyrgeometer with leveling plate.
SL-610 downward-looking pyrgeometer mounted.
Mounting
A thermally-insulated base is included to be mounted between the sensor and leveling plate. The AL-120 Solar Mounting Bracket with Leveling Plate facilitates mounting the sensor to a mast or pipe. The AL-100 Solar Sensor Leveling Plate is designed to level the sensor while sitting on a flat surface or mounting to a surface.
Typical Applications
Applications include longwave radiation measurement in agricultural, ecological, and hydrological weather networks and renewable energy applications.
High Quality Cable
Pigtail-lead sensors feature an IP68, marine-grade stainless-steel cable connector approximately 30 cm from the head to simplify sensor removal for maintenance and recalibration. Cable is shielded, twisted-pair wire with a TPR jacket for high water resistance, UV stability, and flexibility in cold conditions.
Warranty and Support
All Apogee products are backed by an industry-leading four year warranty and outstanding customer support.
