LH-131 IR Power Meter Infrared Irradiometer Infrared Light Irradiance Power Meter Range 1uW/cm²~3000W/m² 760~1100nm

Description

Product Overview

The HOJILA LH-131 IR Power Meter is engineered for professionals who require accurate and reliable infrared irradiance measurements in both laboratory and field environments. Designed with a robust housing and a high‑resolution LCD, the device delivers clear readings across a broad spectral range of 760 to 1100 nanometers. Its measurement capability spans from ultra‑low levels of 1 µW/cm² up to high intensities of 3000 W/m², making it suitable for a variety of applications such as photobiology research, semiconductor processing, solar panel testing, and medical device validation. The meter incorporates a built‑in temperature sensor, allowing users to correlate irradiance data with ambient temperature, which is essential for experiments where thermal effects influence optical performance. With a storage capacity for 100 separate data sets, users can log and retrieve measurement histories without the need for external equipment.

Usage

In laboratory settings, the LH‑131 excels at characterizing light sources, verifying LED output, and calibrating photometric equipment. Its compact size—measuring just 13.39 × 9.49 × 3.58 inches—and lightweight design (1.59 lb) enable easy placement on optical benches or integration into custom test rigs. Field technicians benefit from its rugged construction and battery‑operated flexibility, allowing accurate measurements of solar irradiance, infrared heating systems, and remote‑sensing devices in outdoor conditions. The intuitive interface requires only a few button presses to select measurement mode, set the desired wavelength range, and initiate data capture, reducing the learning curve for new users while maintaining precision for seasoned professionals.
