Outstanding Features

3-in-1 optical analysis: The device allows a comprehensive evaluation of a material’s transmission/blocking capability for the 3 most important light bands:

• Visible Light (VLT – Visible Light Transmittance): Determines the brightness/darkness level of the glass; the higher the light transmittance, the more transparent the glass.
• Ultraviolet (UV): Evaluates the UV rejection capability, a crucial factor in protecting human health and preventing interior fading.
• Infrared (IR): Measures the transmission or heat rejection rate from infrared rays, the deciding criterion for the quality of window tint films.

Handheld Slot Design: With its characteristic measurement slot design, users simply clip the device onto the edge of a glass pane, car window, or film to get immediate results without destroying or cutting the sample.

Independent Operation & Anti-interference: The device is equipped with a synchronized light source and a highly sensitive sensor. This technology helps the device operate stably and provide accurate results even when used in outdoor lighting environments.

Auto-calibration: The smart calibration feature automatically resets parameters to the 100% level when there is no obstruction in the measurement slot, ensuring absolute accuracy before each test.

Instant result display: The digital screen simultaneously displays all 3 parameters with a clear layout. The intuitive interface allows anyone to easily read, understand, and evaluate product quality without complex training.

Practical Applications

With the perfect combination of mobility and accuracy, the CHN SPEC CT-23 is a powerful assistant in the following fields:

• Window tint film industry (Automotive & Architectural): Serves as an effective “sales closing” tool, helping consultants visually demonstrate the UV and infrared (IR) rejection capabilities of various tint films right in front of customers.
• Architectural glass production: Evaluating the optical quality of laminated safety glass, tempered glass, and Low-E glass at construction sites.
• Eyewear industry: Quickly inspecting the anti-glare capability (reducing VLT) and UV protection of sunglasses and safety glasses.
• Plastic and acrylic material inspection: Measuring the transparency and light-blocking capability of polycarbonate, acrylic sheets, or specialized packaging plastic films.
