Johnson Level 40-6616 Tiling and Flooring Laser Level Review
In this article we will discuss Johnson’s new generation of laser level, which is called Bosch PLT2. The laser level is manufactured by Bosch Plasmasysteme GmbH (Bosch). Bosch PLT2 laser level was introduced in October 2012.
Its name comes from its two letters: PLT stands for “Plasma Technology” and 2 means it is a second generation model. Bosch PLT2 laser level uses a liquid crystal display (LCD) panel with two backlight zones. One zone displays the image while the other one shows the reading of the laser beam. The LCD panel provides better contrast ratio than conventional flat screen monitors.
The Bosch PLT2 laser level offers different levels of brightness, ranging from very low to very high brightness levels. The higher the brightness level, the brighter the image displayed on the LCD panel. Higher brightness levels are achieved through a larger number of LEDs and smaller power consumption.
Bosch PLT2 laser level has a maximum operating temperature range between -40°C to +85°C (-40°F to 185°F).
One of Bosch PLT2 features is its automatic calibration feature. The automatic calibration function enables the user to make fine adjustments to the accuracy of the laser level. The display shows an error message if a calibration is required.
If the error message is displayed, the user should point the laser level at a horizontal surface (wall or ceiling) at a distance of between 2 and 7 meters (6.5 to 23 feet). The unit will automatically calibrate itself to correct any possible misalignment. The error message may also be caused by the laser beam reflecting off a shiny surface. In this case, switch OFF the laser level and turn it ON again after 15 seconds. This is to avoid over-driving the automatic calibration function.
The laser level can be used in three different modes: horizontal, vertical and corner. The corner mode works only if there is a clear sight at all three corners. The vertical mode can be used to measure from one floor to another, such as the ceiling of a basement and the floor of a room or the floor of one room and the ceiling of another.
For example, plumbers use this mode to measure from the bottom of a tub to the top of a wall. In this case, the corner mode is not necessary. Another mode is the horizontal mode for example when laying floor tiles.
Bosch PLT2 laser level is supplied with a soft carrying case, a built-in tripod, and two AA batteries. The unit can also be powered by an AC adapter, which is sold separately. The dimensions of the laser level are: 10.4 x 3.1 x 1.8 inches and its weight is 1.76 lbs.
The product is backed by a three-year limited warranty.
The community says that this unit is very easy to use. It is very accurate and easy to calibrate. It is also very durable and has a long battery life.
The only negative comment about this product is that the carrying case could be better.
So if you are looking for a high quality, durable, easy to use product then the Bosch PLT2 is the laser level for you. In fact, the majority of people who have purchased this product would recommend it to others.
