Upgrade the kit to include the Spectra HL450 Detector


The Spectra Precision HL450 Detector is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating laser level.

The HL450 features a digital readout of elevation that provides a numeric display of ±40 mm to 1mm resolution. The readout is displayed on the large front and rear LCD's and shows exactly how far the elevation is from on-grade.

Accurate measurements can be made without moving the rod clamp, saving time and increasing productivity.

The HL450 has a 102 mm (4 inch) reception height, double the typical industry standard, which allows quick acquisition of the laser beam. Also included is a patented anti-strobe sensor that prevents construction lights from setting off the Detector and makes it easier to identify the laser beam signals.

The Detector is designed to survive the tough construction site conditions. It is totally waterproof (IP67) and can withstand a drop up to 1.5 meters (5 feet) onto concrete.



Digital Readout of Elevation allows faster readings by displaying the exact numerical distance from grade, eliminating the need to move the detector to get to "on-grade".
Anti-Strobe Sensor stops construction strobe lights from setting off the detector and eliminates phantom strikes for easier identification of true laser beam signals.
Large reception height allows faster readings by acquiring the beam quickly, and makes it easier to stay in the beam.
Durable in tough environments provides less downtime due to damage or service requirements after accidental drops.

HL450 instrument
Alkaline batteries x 2
Mounting bracket
Instruction & safety manual

Calibration and servicing:

We check and calibrate all Lasers prior to dispatch, to ensure they meet or exceed the manufacturers published specifications at the time of shipment from the factory.
If you routinely work on large job sites, which require you to have a physical Calibration certificate, issued in your name and matched to the Laser via its serial number, you must ensure you tick the above box marked "Paper Certificate" (where applicable) to add a Calibration certificate to your order. The Certificate will then be generated and included with your Laser. Please note the issuing of a Calibration certificate DOES NOT delay or hold up the despatch of your Laser in any way.
