    PCE Instruments SPM 1 Solar Power Meter 0 to 2000 W/m²

    # SPM 1

    • PCE-SPM 1 is a photovoltaic (PV) light meter used to measure solar radiation, solar energy or solar power.
    • The meter’s easy-to-read 4-digit LCD screen clearly displays Ptot in W/m² or BTU/(ft² x h), while the device’s auto data memory stores up to 43,000 data sets.
    • Ideal for solar panel site surveying, installation, inspection and monitoring as well as for solar energy research and product development
