Witschi ProofMaster Pressure and Vacuum Tester - HW420B

The new generation ProofMaster – more compact, faster, more accurate.

The latest technology and smart algorithms are part of its DNA.

Based on many years of experience, we present a device that is characterised by the easiest possible operation and parameterisation.

It impresses with rapid and reliable tightness testing, small space requirements, optimal protection of watches against scratching and its ergonomic design.
The ProofMaster is adaptable with two different option packages, the individual requirements of watchmakers, service centres, production facilities and laboratories are covered perfectly.

A later upgrade to the PRO version is possible at any time.

WiCoTRACE The ProofMaster can be used as a stand-alone device or in conjunction with the PC software WiCoTRACE.

This provides additional possibilities for the measurement analysis and the professional administration of parameters and results, either locally or centrally.

• Testing can be carried out with up to three test pressures ranging from –0.7 to 10 bar

• Intuitive operation via the 5 inch touchscreen

• Considerable productivity increase thanks to the new, fast evaluation algorithm

• Fully automatic sensor actuation, as well as closure and locking of the test chamber • ScratchProtect – lowerable watch support offers efficient protection against unwanted scratches

• Shock and vibration detection for increased robustness of the measurement

• Display of rate, beat error and amplitude when a ChronoMaster is connected

• Connection of a code reader for the identification of the watch or selection of a WiCoTRACE test program

Requires a compressor capable of minimum 11 Bar output pressure (Our Ref. HW441).
