Full Description

The Topcon RL-HV2S Dual-Slope Rotating Laser is designed for professionals who need flexibility across a wider range of site applications. Suitable for construction, engineering and interior fit-out projects, it supports both horizontal levelling and vertical alignment, making it a practical solution for varied layout requirements. In horizontal mode, the RL-HV2S establishes a stable reference plane for tasks such as site levelling, concrete preparation and general height control. When switched to vertical operation, it provides a clear reference line for wall alignment, column setting, façade work and other layout applications where plumb accuracy is essential. This dual-function capability makes it particularly useful on projects that move between groundworks and structural or internal stages. The laser features an automatic self-levelling system that helps ensure consistent accuracy while reducing setup time on site. Once levelled, it delivers reliable performance across short and medium working distances, especially when used with a compatible, digital laser receiver such as the popular LS100D. Housed in a robust, weather-resistant casing, the RL-HV2S is designed to cope with dust, moisture and everyday handling on active sites. Straightforward controls and clear indicators allow quick setup and repositioning, helping maintain productivity throughout the working day. Supplied in a protective carry case, the Topcon RL-HV2S is well suited to general construction levelling, vertical layout, structural alignment, and interior or exterior setting-out, offering a flexible and dependable laser solution for multi-stage projects.

FAQs

What is the primary difference between the Topcon RL-HV2S and the RL-H5A?

While the RL-H5A is primarily a horizontal laser, the RL-HV2S is a “multi-task” dual-grade laser. It allows for precision grading on both the X and Y axes, making it suitable for complex drainage, roading, and site preparation projects where dual slopes are required.

How long will the battery last on a typical shift?

The RL-HV2S provides approximately 65 hours of continuous use with the rechargeable Ni-MH battery pack. In an emergency, it can also run on standard alkaline batteries for up to 120 hours, ensuring that power issues never cause downtime on your project.

Can I hire the Topcon RL-HV2S for a specific grading project?

Yes, the RL-HV2S is a popular choice in our hire fleet for contractors needing dual-grade precision. Every hire kit from PQS Survey Ltd includes the laser, a digital receiver, a tripod, and a staff, all fully calibrated and site-ready.

Can I control the RL-HV2S from my smartphone?

Yes, the RL-HV2S features integrated Bluetooth connectivity. Using the “Laser Manager” app, you can change grade settings, adjust rotation speeds, and check battery status directly from your phone, which is a major advantage for one-man operations.

Does this laser work for vertical alignment as well as horizontal grading?

The RL-HV2S is designed for both horizontal and vertical applications. It can be turned on its side for layout and alignment tasks, such as squaring off foundations or aligning vertical steelwork, making it a highly versatile tool for multi-phase groundworks.

What is the operating range of the Topcon RL-HV2S?

This laser offers an expansive working diameter of up to 800 metres. This long-range capability ensures that you can cover significant site areas from a single setup, maintaining consistent accuracy across large-scale bulk earthworks or infrastructure projects.

How does the “Slope Masking” feature benefit a busy construction site?

The RL-HV2S allows you to “mask” or turn off the laser beam in specific directions. This prevents the beam from reflecting off glass or interfering with other laser receivers on-site, ensuring that your team and other contractors don’t receive false readings.

What happens if the laser is accidentally bumped during a pour?

The unit features a “Height of Instrument” (HI) alert. If the tripod is disturbed or the laser is knocked, the head stops rotating and alerts the operator. This fail-safe ensures you don’t continue working with an incorrect datum, protecting the integrity of your levels.
