The LTC-502 leak tester is the startup model in our successful LTC leak tester series. The LTC-502 enables the complete functionality of the PC to be used for rapid and precise measurements of pressure differences and flow, even in extreme situations. The integrated PC leaves nothing to be desired when it comes to user-friendliness. The future-oriented control using one button is intuitive and easy to operate. Inputting errors are prevented. In addition, all parameters are easily manageable, so the subsequent assessment of the measuring processes can be carried out without difficulty. The LTC-502 communicates directly with all the peripherals for transfer, management and analysis of data and machine control. The test process becomes noticeably more efficient. Another technological innovation is the unique analog module with the 24-bit A/D converter. The module enables an unequalled detailed discrimination of the measuring signal. This means that a huge amount of extra information is available for monitoring the measuring process and ensuring that the measurements can be reproduced as accurately as possible. Considering the outstanding measuring concept and the wide range of different functions, the LTC-502 is on sale at a particularly attractive price. This makes it an investment with an assured future on all fronts.

LTC-502 – the innovation for standard solutions

The LTC-502 puts into practice the know-how and

experience of more than 30 years in leak test technology. It can be used for the most diverse test specifications, such as:

• Test pressures – from vacuum to 20 bar over-

 pressure

• Test times – in milliseconds, seconds and minutes

• Leak rates – for all kinds of functional leakage tests

• Pressure differences – from 0.1 Pa to 5000 Pa

• Test volume – from a few millilitres to 10 litres

• Environmental conditions – with special adaptations for a wide range of sectors (temperature, etc.)

The LTC-502 offers virtually unlimited possibilities for all kinds of leak measurement tests using the differential pressure and flow methods.

Good contactual characteristics and connection guarantee

The PC platform and the software developed for the LTC-502 enable the connection of peripherals such as:

• Printer with USB interface

Measurement and Quick Connector Systems

The DIGIFLOW 2003 is a variable leak calibrator which is used to professionally test leak measuring devices and/or entire leak test systems for quality assurance. The DIGIFLOW 2003 will be connected in parallel with a dense sample which leak rate will be checked and adjusted on the DIGIFLOW 2003.

The leak measuring device or the leak test system has to recognise the leak simulated by the DIGIFLOW 2003. In this way, the efficiency of the entire test system can be easily, quickly, and cost-effectively controlled – at every opportunity, shift changeover, tool change, or special incidents.

The innomatec test leak can be used for all test methods (pressure difference, flow, tracer gas). Appropriate accessories and adaptions for the connection to your equipment are available. It can also be directly integrated into a test piece.
