The pro900 series is the ideal when it comes to electronic spirit levels. A rigid three-chamber powder-coated profile impact-absorbing caps and a high ip65 protection class. A spirit level that will last for years. The spirit level has two easy-to-read backlit lcd displays. Additionally two vials and one handle. we placed the electronic module in the ultra-durable three-chamber symmetrical profile known from the pro900 spirit level. We did this without damaging the central chamber. This makes the level durable and the module well protected.the intuitive control panel allows easy access to functions. View one of the two backlit displays from any angle. Conveniently read high-accuracy measurements in difficult working conditions. The electronic module enables precise measurement across a wide temperature range with an accuracy of 0.1° when determining angles of 0° and 90°. In the range of 1°-89° the accuracy is 0.2°.functions such as sound signaling measurement unit selection measurement memory relative measurement and self-calibration will allow you to work more precisely efficiently and conveniently.**illustrative photos
