Features
High-Definition Color Screen for Clear Data Display
The device features a high-resolution color screen that shows IR and UV rejection rates, along with visible light transmittance. Color-coded progress bars make it easy to interpret results at a glance.
Multiple Display Modes
Users can choose from several display modes, including rejection rate, transmittance, and single transmittance display, to suit different testing needs.

Fast and Easy Measurement
The instrument is simple to use—no complex setup required. Just insert the film into the test slot, and it instantly displays the results.
Data Hold Function
Pressing the HOLD button freezes the current data on the screen. The readings remain visible even after removing the material from the test slot.


Compact and Portable

Real-Time Dynamic Calibration
The meter features real-time self-calibration. When no material is in the test slot, it automatically calibrates to ensure measurement accuracy.


Auto-Rotating Display for Convenient Use
The screen automatically adjusts its orientation based on device rotation, making it easy to read data and operate buttons from any angle.


Ultra-Low Power Consumption
Powered by four AAA batteries, the device delivers long-lasting performance. An intelligent power-saving mode automatically turns off the unit after three minutes of inactivity.
