Red White Reflector Sheet For Total Station Reflective Tape Target Sheet Instrument Accessories (100pcs)

A red white checkered reflector sheet is a self-adhesive, passive reflective target used with total stations to return laser signal for fast, accurate distance and angle measurement. Supplied in packs of 100 pieces and available in five sizes from 20x20mm to 60x60mm, these high-contrast checkerboard targets are built for surveying, construction layout, tunnel monitoring and structural inspection work where a compact, budget-friendly alternative to a glass prism is needed.

Unlike plain white or single-colour reflective stickers, this reflector sheet for total station uses a four-quadrant red-and-white checkerboard face. The alternating high-reflectivity squares create a sharp visual and optical boundary at the centre of the target, which makes it easier for a total station operator (or a camera-based measurement system) to identify the exact centre point of the sheet, even at longer ranges or in variable light. The material is a self-adhesive reflective sheeting, similar in reflective performance to commercial-grade (3M-equivalent) reflective tape, backed with a peel-and-stick adhesive layer for tool-free installation on concrete, metal, glass, plastic and timber surfaces.

Key Features of the Red White Reflector Sheet

1. High-Contrast Checkerboard Pattern for Precise Centring

• Four-quadrant red/white layout gives a clear, symmetrical aim point
• The strong colour contrast is easy to distinguish from natural backgrounds (concrete, brick, soil, foliage)
• Well suited to close-range and photogrammetry-style targeting where corner/centre detection accuracy matters

2. Five Sizes for Every Working Distance

• 20x20mm compact size for confined spaces and short-range work such as tunnel or utility surveys
• 30x30mm balanced size for general-purpose site surveying
• 40x40mm mid-range target for slope monitoring and structural checks
• 50x50mm larger target for outdoor projects needing stronger, more visible reflection
• 60x60mm largest option, best for long-distance total station measurement

3. Self-Adhesive, Peel-and-Stick Application

• No tools, brackets or mounting hardware required
• Adheres firmly to concrete, metal, glass, plastic and painted surfaces
• Fast to deploy across multiple monitoring points on a single site visit

4. Bulk Pack of 100 Sheets

• 100 individual reflector sheets per order, per size
• Reduces per-unit cost for large-scale or repeat-use projects
• Spare stock on hand for sheets that are damaged, lost or reused across sites

5. Weather-Resistant Reflective Surface

• Built to tolerate dust, moisture and temperature swings on outdoor sites
• Suitable for both short-term set-out work and longer monitoring campaigns

Applications of the Red White Reflector Sheet

Construction & Site Layout

Fast, low-cost reference points for layout marking, alignment checks and structural positioning.

Tunnel & Subway Engineering

The high-contrast pattern stays easy to distinguish in low-light underground conditions.

Slope & Structural Monitoring

Multiple sheets can be placed across a slope, wall or bridge to track movement over time.

Land & Geodetic Surveying

A compact, disposable alternative to a prism for boundary marking and topographic work.

How to Install a Red White Reflector Sheet

1. Clean the surface remove dust, grease and moisture so the adhesive bonds properly
2. Peel the backing remove the protective liner from the adhesive layer
3. Position the target centre the checkerboard pattern on the reference point
4. Press firmly apply even pressure across the sheet for full adhesion
5. Sight and confirm point the total station at the target and confirm a clean return signal

Red & White vs. White Reflector Sheets: Which Should You Choose?

If your site already uses white crosshair reflector sheets or white round-grid reflector sheets, the red/white checkerboard pattern is a useful complement rather than a straight swap: the colour contrast makes it faster to spot visually on cluttered or light-coloured backgrounds, and the four-quadrant layout gives a very clear centre point for close-range and photogrammetry-style work. Many surveyors keep both pattern types on hand and choose per job based on background contrast and viewing distance.

Frequently Asked Questions

What is a red white reflector sheet used for?

It is a self-adhesive reflective target used with total stations to provide a fast, accurate reference point for distance and angle measurement in surveying, construction and monitoring work.

What size reflector sheet should I use?

Use 20x20mm or 30x30mm for confined spaces and short-range work, 40x40mm for general slope or structural monitoring, and 50x50mm or 60x60mm for outdoor projects and longer-range measurement.

Is the red white pattern more accurate than a plain white target?

The checkerboard pattern does not change the reflective material’s return performance, but its high colour contrast and clear centre point can make the target easier to sight and centre on quickly, particularly against light or cluttered backgrounds.

Are these reflector sheets compatible with all total stations?

Yes. As a passive reflective target, this sheet works with total stations from all major brands, including Leica, Trimble, Topcon and Sokkia.

Can these reflector sheets be used outdoors?

Yes, the reflective material is weather-resistant and suitable for outdoor construction, monitoring and survey sites.

Do I need tools to install these reflector sheets?

No. Each sheet has a self-adhesive backing, simply peel and stick to a clean, dry surface.

Can reflector sheets be reused?

They are designed as a single-use adhesive target. Once removed from a surface, the adhesive backing generally will not provide a reliable second bond.

How many sheets are in a pack?

Each size is sold in packs of 100 pieces.
