Johnson Self-Leveling 2-Dot Laser Level Review — With the use of self-leveling pendulum system, the Johnson Self-Leveling 2-Dot Laser Level makes ascertaining precisely plumb areas simple. Set the Johnson Self-Leveling 2-Dot Laser Level on a sensibly level surface (+/ – 3-degrees) and the rest is done by the machine. The pendulum utilizes gravity to splendidly adjust the laser beams so you can concentrate on doing your work and make sure that it is plumb.
The laser unit is comprised of the Johnson Self-Leveling 2-Dot Laser Level, direction manual, case with belt loop, a graduated target, and AA batteries. You truly can purchase this unit and directly to work. Johnson additionally offers the #40-6675 model that is indistinguishable to the Johnson Self-Leveling 2-Dot Laser Level with the exception of that it includes a front horizontal laser beam that is precisely 90-degrees to the two plumb dots.
Johnson Self-Leveling 2-Dot Laser Level Review
The Johnson Self-Leveling 2-Dot Laser Level is 4.212″ – wide by 4.528″ – tall by 2.598″- and weighs only 0.127lbs (0.58kg) so transporting it to the worksite is not an issue. It is controlled by three AA batteries (provided) that should last up to 50-hours of run time so you won’t be needing new batteries all the time.
The Johnson Self-Leveling 2-Dot Laser Level (#40-6670) utilizes a Class IIIa laser with a greatest yield of <=5mW. This laser has an inside range up to 100ft a precision of +/ – 1/8″at 50ft (+/ – 2mm/10m). (30m) contingent upon the encompassing light conditions normally. The laser has a wavelength of 650nm +/ – 10nm (Red). As brilliant as the Johnson Self-Leveling 2-Dot Laser Level, it has been amid this assessment under photo lights, some users experience considerable difficulties that the laser specks will vanish in anything besides the most horrible conditions.
The extreme plastic case has elastic over molds deliberately situated to make it comfortable to the hand, slip safe and resistant to a portion of the thumps of being transported from one work-site to another. While the Johnson Self-Leveling 2-Dot Laser Level can be just set down on a sensibly level surface the case has bushing in the base with 1/4″- 20 strings to make it perfect with basically any of the ca-zillion or so camera stands and tripods available.

Utilizing the Johnson Self-Leveling 2-Dot Laser Level is more or less simple. You do need to concoct a kind of level surface that is inside 3-degrees +/ – of level for the inner pendulum component to make that laser beams really plumb consequently. In the event that you cannot make a surface that is inside 3-degrees of level you truly need to back off and focus somewhat more! The Johnson Self-Leveling 2-Dot Laser Level will tell you that it is not sufficiently level with the flashing of the laser and a progression of audible beeps. Those pointers go noiseless when you get inside the +/ – 3-degrees sweet spot.
The Johnson Self-Leveling 2-Dot Laser Level has a handle on the side that switches the laser on and off. That same handle likewise bolts the pendulum component when the laser is switched off so it won’t be harmed amid transfer. The manual gives clear directions for checking the alignment of the Johnson Self-Leveling 2-Dot Laser Level, something you ought to be doing every now and then with any accuracy instrument. There are ports for adjustments on the front and in the ON\OFF handle to get to the adjustments (internal) just in the event that the Johnson Self-Leveling 2-Dot Laser Level requires tweaking.
The front edge of the Johnson Self-Leveling 2-Dot Laser Level has a 2” tall by ½” deep break that slips over basic surrounding materials to put the laser spot precisely on the edge. At that point the vertical beam sparkling on the roof or upper surface is precisely plumb to that edge. The recess likewise has magnets set into the surfaces that helps hold it unmoving against things like steel confining materials.
Installing pretty much anything that should be plumb simply does not get substantially easier than with the Johnson Self-Leveling 2-Dot Laser Level. It seems to be well fabricated and is as exact as one can figure out how to measure. You should simply come to an obvious conclusion!
