Spectra HL450 Digital Laser Receiver with 4″ Reception Height

Description

PRODUCT DESCRIPTION
The Spectra HL450 Digital Laser Receiver provides numerical elevation readings for levelling, grading, concrete work, excavation, and site preparation. Its 4-inch reception height helps the receiver acquire the rotating laser beam quickly, while large front and rear LCD screens make grade information visible from either side of the rod.
The digital readout shows the exact distance from on-grade within a ±40 mm or ±1.5-inch range, allowing the operator to check cut-and-fill measurements without repeatedly repositioning the receiver. Selectable measurement units, proportional grade arrows, adjustable audible signals, and an anti-strobe filter make the HL450 practical for accurate everyday layout and elevation work.

FEATURES
• Digital readout displays the exact distance from on-grade within ±40 mm or ±1.5″
• Selectable units include millimetres, centimetres, feet and inches, and fractional inches
• Front and rear LCD screens display proportional arrows for quickly locating on-grade
• Adjustable audible signal indicates whether the receiver is high, low, or on-grade
• Anti-strobe filter helps prevent construction warning lights from causing false readings
• 4″ reception height helps acquire and remain within the laser beam
• Designed to withstand drops of up to 3 m (10 ft) onto concrete
• IP67-rated housing protects against dust, water, and demanding jobsite conditions
• Powered by two AA batteries for extended operating time

FOR GRADING AND ELEVATION WORK
The HL450 is a practical choice for crews that want exact cut-and-fill readings without the wireless functions of the HL760. It provides more information than a basic high, low, and on-grade receiver while remaining straightforward for everyday grade-rod use.
