Laser Level Gauge 635nm Red or Green Beam 10m Working Distance

This laser level gauge is a marking instrument for wall sticking and ground line casting. It projects a 635nm beam with a 3mm accuracy and a 2mm line width, giving you a visible reference for alignment work. The working distance reaches up to 10m, so it can cover typical room dimensions without repositioning. The device runs on 2 AA batteries and is available in two specifications: SW-311R with a red light and SW-311G with a green light. Its compact body measures 65.4 x 75 x 76mm. The working temperature range is -10 to 50 degrees. If you need a straightforward tool for setting out lines on walls or floors, this unit provides the core functions without extra complexity.

Features and Construction

The gauge is built around a 635nm laser module and is supplied in red or green beam versions. The listed accuracy is 3mm, and the line width is 2mm. These figures describe the beam and its output rather than the housing material, which is not specified in the source text.

Material and Build

No specific housing material is stated. The product information lists the laser wavelength, accuracy, power supply, dimensions, working distance, working temperature, and line width. The unit is identified as a laser level gauge and marking instrument. It is designed for wall sticking and ground line casting. Because the source text does not name the body material, no claim is made about impact resistance or weather resistance beyond the stated working temperature range of -10 to 50 degrees.

Size and Practical Fit

The dimensions are 65.4 x 75 x 76mm. This compact size allows the gauge to be placed on a wall or floor for line casting. The working distance is up to 10m, which is relevant for indoor alignment tasks. The 2mm line width and 3mm accuracy are the stated beam characteristics. The unit uses 2 AA batteries, so no mains cable is required during use. These details are the full set of measurements provided in the source text.

Uses and Placement

This instrument is intended for wall sticking and ground line casting. It can be used where a straight reference line is needed, such as when aligning fixtures or checking floor and wall positions. The red and green options allow you to choose the beam colour for your working environment.

Event or Professional Use

For trade or site work, the 10m working distance and 3mm accuracy provide a practical line for marking. The 635nm wavelength is within the visible spectrum, and the line width is 2mm. The working temperature range of -10 to 50 degrees covers many indoor conditions. The unit is powered by 2 AA batteries, making it easy to carry and set up. The source text does not list certifications or outdoor ratings, so those claims are not made.

Everyday Home Use

For home projects, this laser level gauge can help with wall sticking and ground line casting when you need a straight guide. The compact 65.4 x 75 x 76mm body can be placed where needed, and the 10m working distance is suitable for typical rooms. The red or green beam option lets you pick the specification that suits your visibility. The 3mm accuracy and 2mm line width are the stated figures. No additional accessories are confirmed in the source text.

Benefits and Buying Value

The main value comes from having a visible 635nm beam, a 10m working distance, and two colour options in one product line. The unit runs on standard AA batteries and has a stated working temperature range. These are practical details for alignment work.

Reuse and Low Maintenance

The gauge uses 2 AA batteries, which can be replaced when needed. No care instructions are provided in the source text, so only basic handling is advised: keep the unit dry and store it away from excessive heat. The working temperature range is -10 to 50 degrees, and the dimensions are 65.4 x 75 x 76mm. There is no stated maintenance schedule or serviceable parts list.
