LS183 (Model): Product Features: 47mm notch, capable of measuring three parameters: 365nm ultraviolet, full-band visible light, and 940nm infrared.
The LS183 Optical Transmittance Meter is mainly suitable for testing the optical properties of regular transparent materials such as glass, thermal insulation coatings, plastics, and organic glass. It can simultaneously test the transmittance of ultraviolet, infrared, and visible light. Adopting a parallel optical path and a 47mm wide notch design, the data for testing large-thickness materials is also accurate.
Core Advantages:

Adopting parallel optical path design, the data is not affected by the sample placement position.
47mm wide notch design, can measure large-thickness materials, with wide application.
Large LCD display, can switch between Chinese, English and graphic display interfaces.
Power-on self-calibration and real-time dynamic self-calibration ensure data accuracy.
A support rod is included as a gift, making it more convenient to read when placed obliquely with support.
Powered by 5V power supply, can be connected to a mobile power supply (power bank) for use.
