Digital Car Window Tint Meter TM-28 VVV Group Auto-Calibrate Rotatable

Description

Product Overview

The Digital Car Window Tint Meter TM-28 by VVV Group is engineered for automotive professionals who demand exacting accuracy when evaluating side window tint films. Built around a high‑resolution LCD panel, the device delivers clear numeric readouts for visible light transmission (VLT), ultraviolet rejection (UVR), and infrared rejection (IRR). A precision‑machined 15 mm slot accommodates a wide range of glass thicknesses, from thin factory‑installed films to thicker aftermarket laminates. The meter operates on a rechargeable lithium‑ion battery that provides up to 20 hours of continuous use, eliminating the need for frequent battery changes. An automatic calibration routine runs each time the unit is powered on, guaranteeing consistent performance without manual adjustments. The rotatable display can be positioned at any angle, allowing technicians to read results comfortably whether the meter is held upright, tilted, or placed on a workbench.

Usage

Designed for both shop‑floor and field applications, the TM-28 excels in a variety of environments. In a professional tinting studio, technicians can quickly verify that each installed film meets local legal limits for visible light transmission, ensuring customer satisfaction and regulatory compliance. Mobile installers benefit from the meter’s compact size—measuring just 10.8 × 7.5 × 3.1 inches—and its rugged construction, which withstands the occasional drop or bump during on‑site work. The device is also valuable for law‑enforcement officers conducting roadside inspections, as the instant readout and rotatable screen reduce the time needed to assess compliance. Whether you are testing a single vehicle or conducting batch inspections in a fleet maintenance facility, the TM-28 provides reliable data that can be recorded manually or entered into a digital log for traceability.

FAQ

How does the automatic calibration work?

When the meter is turned on, internal sensors compare the current light source against a built‑in reference standard. The device then adjusts its measurement algorithm automatically, ensuring that each reading reflects true transmittance values without any user‑initiated calibration steps.

Can the TM-28 measure both UV and IR rejection accurately?

Yes. The meter uses separate photodiodes calibrated for ultraviolet and infrared wavelengths, delivering separate UVR and IRR percentages alongside the visible light transmission figure. This three‑parameter output helps professionals verify that tint films meet both comfort and safety specifications.

Is the device suitable for use on curved windows?

The TM-28’s slot is designed for flat surfaces, but it can still be used on gently curved side windows by positioning the sensor flush against the glass. For heavily curved or domed windows, a specialized adapter is recommended to maintain measurement accuracy.

What is the warranty period?

VVV Group provides a one‑year limited warranty covering defects in materials and workmanship. Customers can contact the support team for repair or replacement services within this period.

How do I export the measurement data?

While the TM-28 does not have built‑in wireless connectivity, users can manually record the displayed values or use a smartphone camera to capture the screen. The data can then be entered into a spreadsheet or inventory management system for tracking and reporting.
