PCE Instruments PCE‑SPM 1 Solar Measuring Device

The PCE‑SPM 1 is a compact, handheld solar radiation meter delivering precise performance for solar engineers, architects, installers, and researchers. It measures the total solar energy yield—both direct and diffuse radiation (Pₜₒₜ)—making it ideal for site surveys, PV system testing, and efficiency evaluation.

Key Features

• Wide Measurement Range: 0–2,000 W/m² or 0–634 BTU/(ft²·h), with high resolution of 0.1 W/m² or 0.1 BTU/(ft²·h)

• Reliable Accuracy: ±10 W/m² or ±3 BTU/(ft²·h), or ±5%, whichever is greater (in direct sunlight)

• Fast Sampling: Takes measurements up to four times per second

• Built‑in Data Logger: Automatically stores up to 43,000 readings (manual memory holds 99)

• Extended Battery Life: Powered by four AAA Li-ion batteries—provides approximately 16 days of continuous use

• Comprehensive Functions: Includes min/max records, data hold, and evaluation software in English for seamless data analysis

• Durable & Portable: Weather-resistant plastic housing, compact size (111 × 64 × 34 mm) and light weight (≈158–165 g) ensure comfortable one-handed operation

• PC Connectivity: RS‑232 interface for direct data transfer to a PC using the included cable and software
