About This

• PROFESSIONAL LIGHT TRANSMITTANCE METER FOR SOLAR FILM CONTROL — TM-26 is designed for quality control and precise light transmission testing of automotive solar films and tinted side windows. Suitable for inspection, installer verification and professional film demonstration.
• MAKE SURE YOUR CAR TINT IS LEGAL — Ideal for testing Visible Light Transmittance (VLT) of car side windows. Insert the glass into the 8 mm slot and instantly receive accurate transmission data together with Ultraviolet Rejection (UVR) and Infrared Rejection (IRR) values.
• MEASURES VLT, UVR & IRR IN ONE DEVICE — Determine tint darkness percentage, infrared rejection rate and ultraviolet rejection rate in one compact meter. All essential light performance parameters are displayed clearly in percent (%).
• AUTOMATIC SELF-CALIBRATION ON STARTUP — The device performs automatic zero calibration every time it is powered on. For accurate baseline adjustment, the 8 mm (1/3 inch) measurement slot must remain completely empty and unobstructed during startup.
• EASY SAMPLE INSERTION UP TO 8 MM (1/3 INCH) — The connector slot supports automotive glass or installed tint film up to 8 mm thick, making it suitable for most standard car side roll-down windows.
• DATA HOLD FUNCTION FOR EASY RECORDING — After inserting the sample, briefly press the power button to activate HOLD mode. The measured values remain displayed for convenient reading, documentation and customer presentation.
• IDEAL FOR TINT SHOPS & INSPECTION SERVICES — Designed for automotive tint installers, detailing studios, dealerships and compliance services requiring consistent and repeatable window tint measurement results.
• MEASURES OPTICAL TRANSMISSION — NOT MATERIAL THICKNESS — TM-26 measures light transmission and rejection only. It does NOT measure glass thickness, coating thickness, plastic or polycarbonate panels, laminated windshields, standalone loose film samples, or materials exceeding the 8 mm slot capacity.
