Analog meters are designed to provide accurate, repeatable intensity readings of UV light sources. Ideal for measuring shortwave and longwave UV radiation in the aerospace, military, food, and pharmaceutical industries, as well as nondestructive testing, quality control, and sterilization processes.

Model J-221 makes longwave intensity readings which are sensitive from 300 to 400nm with a peak sensitivity at 365nm

Model J-225 measures the intensity of shortwave UV light sources within the range of 220 to 280nm with a maximum sensitivity at 254nm. Intensity is in two ranges: 0–2400µW/cm2 and 2000–12,000µW/cm2.

Dimensions: 7.6x7.6x7.6cm (3x3x3"). CE marked.

A certificate is provided to indicate instrument traceability to standards provided by the National Institute of Standards and Technology and Analytik Jena’s published standards.

Intensity is in two ranges: 0–1200µW/cm2 and 1000–6000µW/cm2. Complies with government standards MIL-I-Std. 45662A. NSN.6635-488-5451.
