Glass screen protector Unitech HT330 401639G single piece

Glass screen protector designed for the Unitech HT330 handheld device. This single-piece tempered glass layer fits the HT330 display to protect it from scratches, minor impacts and everyday wear while preserving touch responsiveness and screen clarity. The protector is intended for field, retail and warehouse environments where the device is handled frequently and requires reliable front-surface protection.

Advantages

The tempered glass provides a hard surface that resists scratches from metal tools, keys and other abrasive objects without affecting the original touchscreen sensitivity. Optical transparency maintains accurate display colours and legibility under indoor lighting. The single-piece format simplifies inventory and replacement, and the protector’s smooth finish reduces fingerprints and allows easy cleaning with standard screen wipes or microfiber cloths.

Suitable for

• Field data collection and on-site inspections
• Retail point-of-sale scanning and handheld transactions
• Warehouse picking, inventory management and logistics
• Daily mobile device use in environments with frequent handling

How to use

Clean the HT330 screen thoroughly with a lint-free cloth and, if provided, an alcohol wipe to remove dust, oils and debris. Align the protector with the device display edges and any cutouts, then apply from one edge, pressing gently to avoid air bubbles. If small bubbles remain, use a soft card or cloth to push them toward the nearest edge. Allow the adhesive to settle for a short time before returning the device to heavy use.

Usage recommendations

For best results, replace the glass protector if it becomes chipped or deeply scratched to maintain screen protection and touch accuracy. Store spare protectors in a dust-free environment and avoid applying to cracked or heavily damaged screens.
