Building upon the capabilities of the CT-23, the CT-25 offers enhanced functionality by measuring an additional infrared wavelength at 1400 nm and providing a broader visible light spectrum range (380–760 nm) conforming to the CIE photopic function standard. This makes it suitable for more comprehensive light transmittance assessments. Like the CT-23, it features a parallel light path design, supports materials up to 13 mm thick, and offers both manual and automatic calibration. The device maintains a full-color 1.14-inch display, 0.10% resolution, ±2% accuracy, and a rapid measurement time of less than 1 second. Its rechargeable 750 mAh battery ensures portability and convenience.
