SR300 Class A Industrial-Grade Pyranometer

Hukseflux is proud to introduce the world’s first industrial-grade digital pyranometer, designed specifically for PV applications. The SR300 builds upon our market leading internally heated and ventilated SR30 model by incorporating enhanced surge immunity, improved tilt measurement functionality, and expanded real-time diagnostics.

New Features

• Enhanced Surge Protection: The SR300 offers industrial-level immunity to protect against lightning strikes and other surge events. It includes integrated Level 2 surge protection (up to 1 kV max), which can be upgraded to Level 4 protection (up to 4 kV max) with an optional external surge protection device.
• RS-485 Isolation: The integrated galvanic isolation protects the internal communication interface, while enhancing the network reliability and flexibility in design.
• External Grounding Lug: This feature facilitates local grounding of the pyranometer housing to quickly dissipate surge or fault currents, ensuring compliance with NEC industrial environment safety regulations.
• Calibrated Tilt Sensor: The SR300 is the first Class A pyranometer that provides calibrated 3-axis tilt data for remote monitoring of tracking or fixed tilt installations.
• In-Field Diagnostics: An LED status indicator allows on-site technicians to verify the sensor is powered, connected, and communicating.
• Remote Diagnostics: The SR300 provides alerts for internal humidity, leak detection, heater status, and tilt changes, helping to maintain a robust, healthy sensor network.
• Updated Software: The new sensor manager software includes an auto-detect feature, simplifying the process of connecting, configuring, and viewing real-time pyranometer data and diagnostics.
• Dome Protector: This accessory protects the pyranometer dome during transport, installation, and removal.
