This Spectra grade laser comes with the advanced HL760 digital receiver\u00a0which operates at a diameter range of 2,600 feet. With the HL760, this grade laser can also perform applications such as Grade Match, PlaneLok, and Automatic Axis Alignment.<\/p>\n<p><iframe title=\"\" src=\"https:\/\/www.youtube.com\/embed\/kJ-MVKtvRJ4\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><br \/>\nPropuls\u00e9 par <a href=\"https:\/\/youtubeembedcode.com\" rel=\"nofollow noopener\" target=\"_blank\">comment int\u00e9grer une vid\u00e9o YouTube<\/a> et <a href=\"https:\/\/gamstopcancel.com\/\" rel=\"nofollow noopener\" target=\"_blank\">how to get around gamstop<\/a><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<p>Le <strong>Spectra GL622IR<\/strong> grade laser uses an invisible Class 1 infrared laser beam that is perfect for general construction, railway jobs, mining tasks, and other special applications where a visible beam is not safe to use. With an optional RC602N remote control,\u00a0the GL622IR allows\u00a0contractors to make grade changes and begin mechanical alignments remotely up to\u00a0490 feet away. This Spectra dual grade laser also performs quick setups for horizontal and grade tasks.<\/p>\n<p>Le <strong>GL622IR<\/strong> infrared grade laser features a large backlit, graphics LCD display and keypads that allow construction professionals to perform a hassle-free operation. With an IP67 rating, this construction laser can also withstand drop up to three feet. In addition, it uses rechargeable NiMH batteries that power the instrument up to 40 hours which makes the GL622IR a good companion for long hours of work.<\/p>\n<p>&nbsp;<\/p>\n<h3>Spectra Precision GL622IR\u00a0 Features<\/h3>\n<ul>\n<li>Invisible Class 1 infrared laser beam<\/li>\n<li>Range up to 2,600 feet<\/li>\n<li>Leveling accuracy:\u00a0\u00b11\/16\u2033 at 100 feet<\/li>\n<li>Dual grade range:\u00a0\u00b125%<\/li>\n<li>Included HL760 digital receiver<\/li>\n<li>Large backlit, graphics display and keypad<\/li>\n<li>IP67 dustproof and water resistant<\/li>\n<li>Drop resistant up to 3 feet<\/li>\n<li>Use rechargeable NiMH batteries<\/li>\n<li>Up to 40 hours of battery life<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Spectra Precision GL622IR Applications<\/h3>\n<ul>\n<li>General Construction Leveling such as concrete forms, footers and Pads<\/li>\n<li>Dual Slop Grading and Steep Slope Excavating<\/li>\n<li>Precision placement of concrete for critical specification surfaces over long distance and with laser controlled screeds (Automatic PlaneLok)<\/li>\n<li>Drift free general construction vertical alignment and plumb for plus form, tilt up and curtain wall plumbing (Automatic PlaneLok)<\/li>\n<li>General construction vertical alignment and plumb such as anchor bolt and form alignment<\/li>\n<li>\u201cOver the top\u201d sewer and storm drain pipe installations<\/li>\n<li>Sports fields, driveways, ramps and drainage<\/li>\n<li>General construction grading and excavating<\/li>\n<li>Slope work for sports fields, driveways, ramps and parking garages<\/li>\n<li>Steep slope road embankments and ditch banks<\/li>\n<li>Interior construction \u2013 layout of walls and installation of drop ceilings<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Spectra Precision GL622IR Specifications<\/h3>\n<table>\n<tbody>\n<tr>\n<td colspan=\"2\">General Specifications<\/td>\n<\/tr>\n<tr>\n<td width=\"125\">Leveling accuracy1,3<\/td>\n<td>\u00b1 0.5 mm\/10 m,<br \/>\n1\/16\u201c @ 100 ft, 10 arc seconds<\/td>\n<\/tr>\n<tr>\n<td width=\"125\">Grade accuracy1,3<\/td>\n<td>\u00b1 1.0 mm\/10 m,<br \/>\n1\/8\u201c @ 100 ft, 20 arc seconds<\/td>\n<\/tr>\n<tr>\n<td width=\"125\">Grade temperature drift sensitivity<\/td>\n<td>\u00b1 0,3 mm \/ 10 m \/ 1\u00b0C;
