The Senseca LP471UVA Radiometric Probe (developed within the world-renowned Delta Ohm optical instrumentation portfolio, part of the GHM Group Italy) is a precision radiometric measuring head engineered for the quantitative assessment of ultraviolet irradiance in demanding industrial, laboratory, and non-destructive testing environments. It operates in seamless integration with Delta Ohm / Senseca multi-function instruments including HD2102.1, HD2102.2, HD2302.0, and DO9721.

1. CONFORMANCE TO NON-DESTRUCTIVE TESTING (NDT) STANDARDS
The LP471UVA probe is specifically designed to satisfy strict international standards governing UV-A blacklight irradiance verification for flaw detection:
• ISO 3059:2001 & EN 571-1: Non-destructive testing – Penetrant testing and magnetic particle testing – Viewing conditions.
• ASTM E1417 / ASTM E1444: Standard practice for fluorescent penetrant and magnetic particle examinations in aerospace and heavy precision manufacturing.
• Guarantees that inspection booths and UV inspection lamps consistently maintain required irradiance levels (typically ≥ 1000 µW/cm² / 10 W/m²), preventing missed surface cracks or fatigue defects.

2. PRECISION OPTICAL CHARACTERISTICS WITH 365 nm PEAK
• UVA Spectral Band: Measures spectral irradiance across the 315 nm to 400 nm waveband, featuring a steep spectral response peak at 365 nm (the industry standard for UV blacklight lamps).
• Quartz Diffuser with Cosine Correction: Incorporates a high-grade quartz optical diffuser that provides precise cosine response according to Lambert's Law, eliminating angular measurement errors and directional reflectance losses.

3. EXTENSIVE DYNAMIC RANGE & SMART SICRAM TECHNOLOGY
• Broad Measurement Range: Offers exceptional linearity from 1.0·10⁻³ W/m² (0.1 µW/cm²) up to 2000 W/m² (200,000 µW/cm²), seamlessly handling everything from residual ambient UV leakage to powerful industrial UV curing conveyors.
• Intelligent SICRAM Module: The connector is embedded with an onboard EEPROM memory chip that stores factory calibration curves, serial numbers, and measurement unit definitions. The host datalogger instantly recognizes the probe upon connection with zero manual configuration required.
• Heavy-Duty Hardware: Features a 1.5-meter rugged shielded connection cable and a corrosion-resistant metallic housing designed for continuous industrial operation.
