The Spectra Precision® HL450 Laserometer is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating transmitter. The HL450 features a digital readout of elevation that provides a numeric display of ± 40 mm or ±1.5 inches. 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 receiver and makes it easier to identify the laser beam signals. The Laserometer is designed to survive the tough construction site conditions. It is totally waterproof and can withstand a drop up to 1.5 meters (5 feet) onto concrete. Applications Setting and checking jobsite elevation and depth for: cut and fills, general grading, foundation/forms/footing, and excavation. HL450 Features and Benefits Digital Readout of Elevation allows faster readings by displaying the exact numerical distance from grade, eliminating the need to move the receiver to get to "on-grade". Anti-Strobe Sensor stops construction strobe lights from setting off the receiver 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.
Highly versatile receiver for basic and advanced leveling and aligning applications The Spectra Precision® HL700 Laserometer is designed for general, concrete and site preparation contractors. The HL700 is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating transmitter. The HL700 features a digital readout of elevation that provides a numeric display of +/- 5 cm (+/- 2 inches).

The HR150U works with all rotating lasers, including the Spectra Precision Laser HV301G Green Beam laser. Now one high featured, economically priced receiver is available to work with any Green, Red or IR rotating laser.
Features and Operations
The HR150U is a reliable new generation, state-of-the-art receiver designed as a universal receiver that can be used with either red, IR, or green rotating lasers.
The receiver “reads” the laser signal as it is transmitted in a 360° plane from the transmitter. A single bank of photocells located on the front of the receiver detects the laser beam. If the receiver is in the ON condition for more than 30 minutes without detecting any laser beam strikes on the photocell, the receiver automatically turns off. The received laser signal indicates the laser elevation using two LED displays, one mounted on the front and one on the rear, which work with synchronous audible tones. The audio is emitted from an audio port on the receiver’s front panel. A power button turns the receiver on or off. The receiver always starts up with the audio in the ON condition. A loudspeaker symbol indicates that audio is turned on when the unit is turned on or when the beam strikes the photocell. Pressing and holding the Power button for 2 seconds turns off the receiver. The unit’s grade sensitivity is 3 mm (1/8 in).
The LED on the rear panel indicates the position of the receiver relative to the laser beam and corresponds to the front LED display. When the transmitter is moved, the receiver must be moved to the line of the beam to resume operations.
Marking notches etched on the side of the housing are about 2 inches (50 mm) from the top and align with the on-grade portion of the photocell. The notches are used to mark elevation readings.
The HR150U receiver is powered by two AA alkaline, NiMH, or Ni-Cd batteries installed behind a battery door on the back of the unit. The user must provide their own charger when Ni-Cd or NiMH batteries are used. Both red LEDs flashing in sequence indicates the condition of battery life. A general-purpose clamp that snaps into the unit attaches the unit to the grade rod

Spectra Precision® DR400 DigiRod - The Rod-less Grade Checker
The Spectra Precision® DR400 DigiRod™ is a versatile, revolutionary tool that eliminates the need for grade rods when checking grades with a rotating laser. The combination of a laser receiver with digital readout, laser distance meter, and built-in tilt sensor provide the information required to take rod-less, accurate grade readings, even at tilt angles up to 30 degrees.
Various grade rods can be emulated including direct elevation rods, cut/fill rods and indirect reading rods. Units of measure are selectable with the press of a button in meters, decimal feet or fractional inches. Elevation measurements can be taken up to 6 meters (20 feet) and the tilt sensor ensures accuracy by automatically correcting to actual vertical distance. The user simply places the laser distance meter spot on the location a grade check is required, picks up the rotating laser beam anywhere on the reception window, and the distance from ground to the rotating beam is measured and displayed.
Based upon the popular HL700 Laserometer, the DR400 DigiRod functions as a laser receiver and will work with any rotational red beam laser.
As a stand-alone laser distance meter, the DigiRod is designed to give contractors a one-person distance measuring and estimating tool to measure remote and difficult-to-reach places such as high overheads, factory interiors, or over water.
Features and Benefits
Extremely portable, universal system that eliminates the need to carry, transport, or maintain multiple grade rod types
Increases safety, reducing the need to lean over or go into excavations or trenches
Increases accuracy, the internal angle compensation system reduces errors and extra material costs due to tilted grade rods
