Product Specifications

Description


The TR-74Ui Illuminance UV Recorder can simultaneously measure and record illuminance, ultraviolet light (UV), temperature and humidity. In addition to these, the TR-74Ui is also capable of displaying cumulative illuminance and cumulative amount of ultraviolet light in the LCD display. The product is an all-in-one package that includes the data logger unit, sensor and software. By simply connecting to a PC via a USB connection and carrying out a few easy steps, the measurement and recording of data can be started.
