Description
The TES-133 Luminous Flux Meter is a compact and accurate instrument designed for precise measurement of luminous flux from 0.05 up to 7000 lumens, making it ideal for testing LEDs, small lamps, bulbs, and fibre illuminators. It uses a 75 mm integrating sphere to ensure uniform light collection and reliable results, while the 4-digit LCD display with auto-ranging clearly presents measurements across four ranges. With a fast measuring rate of approximately 5 readings per second, high resolution down to 0.001 lumens, and spectral sensitivity closely matched to the CIE photopic curve (f’1 ≤ 6%), the TES-133 delivers quick, stable, and repeatable measurements suitable for laboratory, production, and quality-control environments.
Designed with usability and data management in mind, the TES-133 offers extensive storage with 999 manual memory sets and up to 38,000 data-logging records, supported by RS-232 connectivity and included software for PC analysis. Useful functions such as data hold, automatic data hold, max/min, ratio operation, comparison, and sorting enhance flexibility during testing and evaluation. Powered by six AAA batteries with an impressive 100 hours of battery life, the instrument is highly portable and dependable for long measurement sessions. Supplied with a carrying case, adapter kit, and accessories, the TES-133 Luminous Flux Meter is an easy-to-use, reliable solution for professional light output measurement.
