TOPCON AT-B4A

Optical level TOPCON AT-B4A, which is the successor to the popular model TOPCON AT-B4 in our market, belongs to the group of inexpensive tools and has an excellent price-quality ratio.

  • Measurement accuracy: (24x magnification) The level provides an accuracy of 2.0 mm per 1 km of double stroke.
  • Resistance to difficult working conditions: The built-in magnetic compensator automatically levels the device and thus facilitates work in places with an unstable and vibrating surface, a high level of protection against water and dust (IP66).
  • Resistance to difficult working conditions: The built-in magnetic compensator automatically levels the device and thus facilitates work in places with an unstable and vibrating surface, a high level of protection against water and dust (IP66).
  • Minimum distance to the rail: The device is designed to work with a minimum limit distance of 0.2 meters, which allows leveling without the need to change the position.
  • Ease of use: Endless horizontal circle screws allow you to accurately aim at the target, and a round level with a mirror fixed above it allows you to quickly bring the device into working condition.
  • Compact design: The compact and lightweight metal casing is protected from environmental influences according to the IPX6 standard, it allows to use the tool in all weather conditions.
  • Stable and reliable equipment: The measuring device used on construction sites is subjected to the most demanding endurance tests. Working in dusty rooms and in difficult conditions, surrounded by construction equipment, it must ensure stable operation - the right measurements.

With an increase from 24x to 32x and a lens diameter of 32-46 mm, the levels are able to provide accuracy in determining the difference in height, providing a clear and bright image.

Optical levels of Topcon are known for their resistance to dust and water, which are IP66 protected and, thus, they can be used in difficult conditions - during rain or in a highly dusty environment.

Levels are designed for surveyors, road workers, builders, archaeologists - for all work requiring high accuracy.

TOPCON QUALITY

TOPCON was tested against a number of expected conditions that may be at the work site for product certification for long-term use.

The AT-B series was tested with special inspection equipment to determine full water tightness. AT-B also has the highest environmental performance and durability in the history of TOPCON's automatic levels, which has been verified by testing the dependence on temperature, humidity, vibration and falling.

1. Water Resistance Testing (IP66)

The AT-B series is prepared to withstand powerful water jets from all sides without any penetration inside the structure.

2. Test for resistance to cold and heat

The AT-B series has passed the test of operating temperatures from -20°C to +50°C.

3. Strength tests

The AT-B series has passed rigorous tests of strength, including rotation of the lifting screws, focusing knob and horizontal circle screw.
