Class A Pyranometer

The top choice for those seeking high accuracy and long-term stability. Adhering to ISO 9060 and WMO standards, with Class A accuracy, its 0.5-second response time far exceeds the standard requirement of 10 seconds. Every inflection point of the power generation curve is accurately recorded, which is precisely the "clean data" most valued by power prediction models. Two options are available: analog (ZTP-11) and digital (ZTP-11M). The digital model directly reads irradiance and is plug-and-play, eliminating the need for expensive microvolt data collectors. Each unit comes with a factory-installed sensitivity coefficient, ensuring long-term stability of <0.5%/5 years, requiring almost no recalibration.

Technical Parameters

• Grade and Range: ISO 9060 Class A certified, range 0 ~ 4000 W/m² (280 ~ 3000 nm). Model Differences (Core Selection): ZTP-11 (Analog): Passive, output 0 ~ 50 mV, must be connected to a high-precision microvolt data logger and separately bound to the factory sensitivity coefficient (7~20 µV/(W/m²)). ZTP-11M (Digital): DC 7~26V power supply, RS-485 Modbus RTU output, directly reads irradiance values, suitable for industrial PLC/SCADA networking. Key Advantages: Extremely fast response speed (< 0.5 s, standard requirement < 10 s), excellent long-term stability (< 0.5% / 5 years).
