Trimble Construction Division proudly introduces a new
Interior and General Construction laser to its product
line. The Spectra Precision® Laser HV401 Horizontal
Vertical Laser is ideal for large interior and exterior
easy-to-use HV401 laser has completely automatic
self-leveling capability for consistent, long-range,
accurate measurements. With a one-button operation, the
HV401 laser will level itself in either the vertical or
horizontal positions. The standard RC601 remote control
lets you operate all functions of the unit up to 200 m
(650 ft) away.
Highly rugged design and patent-pending lighthouse seal
protects rotor head and glass to withstand direct drops
up to 1 m (3 ft) onto concrete and a tripod tip over up
to 1.5 m (5 ft)
Reduces downtime due to damage or service requirements
after accidental drops or tip-overs.
IP66 specification for weather and dustproof design
Eliminates downtime due to bad weather/dust conditions
and lowers repair costs over the life of the product.
battery life; operates on NiMH (55 hours of use)
batteries (included) or alkaline batteries (90 hours of
use) can be used as a backup
Extends productivity; work a full week or more before
you need to change or charge batteries.
Multiple power options include rechargeable batteries,
Alkaline, or power directly from the charger.
Reduces downtime due to power loss.
Provides easier setup and less mechanical parts.
remote can be used with the laser up to 200 m (650 ft)
Allows easy slope matching using the remote control from
the rod position and provides access to the single axis
slope mode. This means that one axis is in the manual
mode, while the cross-axis is self-leveling for improved
speed and accuracy of slopes on grade.
mW laser beam with variable rotation speed and scan
Bright, long-range beam can be seen for long distances
and can be concentrated in the work area—even in
Temperature calibrated with an accuracy of 1.5 mm (1/16
in) at 30 m (100 ft).
Provides long-range performance—even at extreme
