The LTL-XL from DELTA: built in modules
The new equipment is offered with a new coloured display, single-handed operation and single touch controls, which makes the operator's work much easier.
Using LED technology, which makes the instrument almost maintenance free, LTL-XL allows users to work efficiently with measuring times of 1-3 seconds and a large memory of more than 200,000 measurements.
"LTL-XL is built in modules to allow the operator to design the instrument according to actual needs. It comes in a base model to which can be added wheels and telescopic handle, GPS and printer," says DELTA.
