Now electronic measuring tape measures have become widespread in big and small construction, having almost completely forced out less convenient analogs with the rolling down/rolling out cloth. The most important plus of the similar tool – lack of need of involvement of the workmate.
First of all, conceived acquisition of electronic tape measure it is necessary to decide on distance of the taken measurements. Ordinary this criterion at standard devices is 150-200 meters.
The peak value is not really relevant for the works performed in rooms, but for external works can be very opportunely. Therefore in the first case it is possible to be limited to limit 50-80 meters which will be quite enough. In the second there will be need of acquisition of the additional tool – the reflecting plate and steady support without which possibilities of human eye will not allow to carry out high-quality work.
The most part of the modern electric tool of this type provides the ultimate accuracy of changes in range of ±1.5-2 millimeters that, according to experienced experts, is quite enough. If there is need to reduce this dispersion of indicators, modern hardware stores offer the clients opportunity to buy more expensive, but also more exact equipment with a margin error ±1 millimeters.
The functionality depends on the list of necessary tasks for which solution the tape measure is necessary. Modern devices are capable to calculate automatically the area and volume of the room, to make addition and subtraction and also to maintain the taken measurements in memory.
The most advanced devices are also supplied with color viewfinder, Bluetooth and the inclinometer.
According to responses at forums of builders, both professionals, and fans, also the possibility of commission of indirect measurement when it is impossible to take direct measurements is valuable in electronic tape measures. Not all models of devices possess also function of possible installation on steady metal support because of lack of internal thread in the tape measure body. Therefore it is necessary to consult the seller about availability of the necessary additions. Unfortunately, some producers still neglect such, at first sight, simple functions as elementary illumination of the digital display and keyboard of electronic tape measure that considerably reduces possibilities of work in night-time or in the dimly lit room.
Availability of digital (optical) viewfinder allows to increase possibilities of measurement and the timer, making delay from direct pressing of the button before measurement performance.
Availability of all above additional functions is not standard for electronic measuring tape measure therefore with presence of each of them also the price of the tool offered in shop increases.
