The automatic, self-leveling Spectra Precision LL400HV Laser Level is the most rugged, long range laser level available, tough enough to handle a wide variety of general construction and vertical alignment applications.

Even in harsh jobsite conditions, the LL400HV delivers consistently reliable and highly accurate performance, enabling you to work faster and smarter. The rugged LL400HV laser can withstand drops of up to one meter onto concrete and tripod tipovers up to 1.5 meters.
This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.

The LL400HV laser's self-leveling capability and RC402N radio remote control result in outstanding accuracy and ease of use.

Each LL400HV laser system now includes the advanced HL760 Digital Readout (DRO) receiver that provides automatic Grade Match, PlaneLok and Fingerprint function.

PlaneLok
The PlaneLok function atomatically locks the LL400HV laser onto the HL760 recevier at an existing elevation or vertical alignment point. This eliminates all drift or possibility of error due to improper calibration or weather. Should the receiver location be moved slightly, the LL400HV will continue to stay locked onto the level location of the recevier.

GradeMatch
The Grade Match function searches then locks onto the HL760 receiver, then measures and displays the existing grade over unknown ground, eliminating time consuming and error prone calculations, time spent searching for grade plans, and over excavating.

Fingerprint Technology
The unique "Fingerprint" function of the new LL400HV allows pairing of the laser and HL760 receiver. It only accepts the beam from the laser it is paired with eliminating levelling errors from detection of other laser beams.


The Spectra Precision LL400HV laser level is covered by a 5 Year manufacturers warranty.

Once shipped from the manufacturer, Accurate Instruments' Calibration and Service Centres check and adjust all instruments on collimators and ranges, then fit them with the appropriate shockwatch, calibration sticker and issue a test calibration certificate.

Shockwatches a damage indicator that alert the user whether the instrument has been dropped.

The Spectra Precision LL400HV is checked, calibrated and certified by Accurate Instruments then fitted with a shockwatch.
