Light and extremely portable. Weights only 400 grams. Packs into a 50 x 20 x 5 cm carrier bag.
Mechanics can use all day long, without getting tired or losing focus. Can be easily carried from site to site for mobile mechanics.
Long battery life. Easily accessible optics.
Maximum productivity and minimum interruptions.
Auto zero-calibration on every power cycle. Robust: can measure even the dirtiest of exhaust gases.
