The 350 H VERSION is particularly suitable for checking cylindrical components to be fixed between dead centres or placed on “V” supports as well as for specimen to be clamped by means of vice.
The picture shows the digital readout included in the standard composition of the instrument for the measurement of linear worktable and screen angular displacements.
The new digital readout MT-1000-C (optional) has an axes display that allows the automatic geometrical data calculation of the specimen.(fig.2)

The 350 V VERSION is suitable for checking small and thin components to be placed directly on the worktable.
This version is therefore useful for small mechanic parts, as well as plastic, rubber, electronic and similar components.
The Data Processor model Quadra Check 221E (optional) has an optical edge finder for the automatic acquisition of the specimen profile.(fig.1)

TRADITION IS A GUARANTEE OF COMPETENCE

A new Profile Projector under the prestigious MICROTECNICA trade mark is a confirmation of tradition now distributed worldwide by LTF. The new HELIOS replaces the previous model designed in 1965 which was purchased by 500 customers all over the World including: Alfa Romeo Auto (I) - Alfa Romeo Avio (I) - Amp Italia - Amp Espanola - Amp do Brazil - Atomic Energy Board (S. Africa) - Brundy Electra (I) - Boehringer Ingelheim (I) - Calibres Ind. & Com. (Brazil) - Eaton (I) - Fiat Auto (I) - Fiat Avio (I) - FN (B) - Gates Europe (B) - Hartford Aircraft (USA) - Honda (I) - Honeywell (I) - Institut de Technologie Appliquee (Marocco) - Itis Pininfarina (I) - Magneti Marelli (I) - Marcel Dassault (F) - Massey Fergusson (I) - Messier Hispano (F) - Metalbox (Singapore) - MTU (D) - Michelin (I) - Olivetti (I) - Piaggio (I) - Prototyp (D) - Rollei Goverment Training Center (Singapore) - Saiag (I) - Teves (F) - Turk Elektrik (TR) - Universität Bremen (D) - Valentie Modco (F) - Vaz (CIS).
The new Helios traces the return of the MICROTECNICA trade mark to the compact/bench top market sector for Profile Projectors with an excellent price/performance ratio.
With the traditional name are all the benefits of the original model: ACCURACY, RELIABILITY, STURDY construction but now technically updated and featuring new electronic measuring systems including PC facility and numerical control.
The new Helios is available in two versions as follows:
- 350-H with horizontal projection system
- 350-V with vertical projection system
Both versions are fitted with a fully usable 350 mm diameter projector screen with digital display for angular measurements as standard.
The difference between the two versions is in the optical projection axis which is horizontal in the 350-H and vertical in the 350-V.
The new Helios enables the MICROTECNICA Profile Projector trade mark to offer a complete range of instruments, which thanks to the highest accuracy, are suitable to meet all current standards including ISO 9001:2000. The other larger MICROTECNICA Profile Projectors are: ORION H and ORION V, Screen Dia. 400 mm - ANTEUS, Screen Dia. 450 mm - ATLAS, Screen Dia. 600 mm and 760 mm - CYCLOP, Screen Dia. 1000 mm.
