Expertise BOC Edwards leak detectors have been used successfully in all the applications listed here and many more. With over thirty years' experience in manufacturing leak detectors, BOC Edwards has the expertise to provide equipment to test anything that should be leak-tight to known specifications. BOC Edwards will work closely with customers to ensure that the leak detectors will enhance the production process and quality control. Custom-built instruments are built to suit customers' exact requirements. Installation, commissioning and servicing are carried out by factory trained engineers and on-site demonstrations of our transportable models can be arranged.

Wide choice for all applications Spectron 600 portable leak detector BOC Edwards offers an easyto-use portable model to the leak detector range, the Spectron 600. This turbo-pumped leak detector is dual flow. In reverse flow it provides fast, quantitative leak detection and in direct flow it becomes a highly accurate, qualitative analytical tool. The Spectron 600 is available in three versions: the 600T, which has an oilsealed mechanical backing pump; the 600D, for those applications that require 100% oil-free leak detection; and the 600DS, a dry leak detector with a stainless steel enclosure, suitable for clean-room operation. The Spectron 600 is particularly suitable for semiconductor fabrication plant where oil-free operation is essential. The Spectron 600 incorporates a helium mass spectrometer, like the standard Spectron 5000, the QLD and the Spectron 300E. Spectron 300E The Spectron 300E is portable and is ideal for furnaces and other large process systems. Spectron 5000 The Spectron 5000 is available in five different models all designed to give consistent, reliable performance in continuous industrial applications. The models are: the general purpose 5000S; the metal-sealed 5000X for ultra-high vacuum; the 5000E-NL for use without liquid nitrogen; the 5000SF for fast testing of small, sealed devices; and the 5000PLC which is designed for use with a programable logic controller. The PLC can be supplied by BOC Edwards or the unit can be integrated with the customer’s own control system. On-board intelligence allows the unit to be controlled through a PC and provides the facility for data collection and reporting. With their extended dynamic range the Spectron 5000 leak detectors are flexible, accommodating present and future requirements.

The new GasCheck range provides automatic and direct display of gas leak rates. At the heart of these instruments is a sensor which can detect any gas that has a different thermal conductivity to that of air, which results in a highly sensitive instrument which is both reliable and compact. The GasChecks are battery operated, making them highly portable. The GasCheck 3000is and 5000is models are intrinsically safe for use in hazardous areas or for the detection of flammable gases. GasChecks detect and accurately display leak rates of gases in five different groups. Gases are grouped according to their responses, enabling selection of the most appropriate group for the application.

Leak detection training BOC Edwards provides courses to train customers in leak detection and has been designated as an Accredited Training Establishment by the British Institute of Non-Destructive Testing for the Mass Spectrometer Leak Detection course.

SPECTRON 600 AUTOMATIC PORTABLE LEAK DETECTOR

Auto Tune Alert The Auto Tune Alert reminds the user to tune the unit every 50 hours of use. Alternatively, the user can select Automatic Auto Tune, and every time the unit is switched on it performs an automatic tuning cycle as part of the start-up process. During the tuning cycle, voltages applied to the mass spectrometer are adjusted and optimized for peak sensitivity and performance.

Calibration Check When testing components with a specified maximum leak rate or if the unit is in use for extended periods, it is advisable to periodically check that it is calibrated to the internal reference leak. This is done by pressing the CAL CHECK button. The unit then performs an independent calibration check without forcing an automatic re-tune cycle. The operator can then decide whether to accept, re-calibrate or re-tune. Competitive models automatically re-tune, giving no option to view the calibration value which creates uncertainty with respect to prior tests.

One-button Auto Tune and Calibration If the operator decides to re-tune the unit, he/she presses the TUNE button. The calibrator valve opens to the mass spectrometer and the anode, filament d.c., focus plates, grid and repeller voltages are automatically tuned. The calibrator valve closes and the amplifier offset and system background is recorded. The calibrator valve opens, the variables are subtracted and the amplifier gain adjusted to the temperature compensated calibrator value.

One-button start up - ready to test in less than 5 minutes Fully automatic operation, tuning and calibration Built-in test diagnostics quickly isolate faults Direct and Reverse flow in a single unit Optional remote control allows testing up to 30 metres from the leak detector Optional sniffer probe allows easy sniffing operation through a dedicated port RS-232 port for connection to automated control systems and personal computers Dual 90° magnetic sector mass spectrometer for the highest resolution Internal temperature-compensated calibrator, traceable to national standards Peak scan facility for positive identification of helium at any time during testing Internal vacuum valves tested for millions of cycles Turbo pump with sealed-for-life bearing

Internal Calibrator The Spectron 600 has a built-in helium 4 calibrated leak, which delivers a specified leak in the range 1 x 10-8 to 3 x 10-8 mbar l s-1 air equivalent. Because leak rates change ± 3.3% ºC-1, the reference leak is temperature compensated and (to aid compliance with ISO-9000 and quality control procedures) it is traceable to NIST (US national standards organization, National Institute of Standards and Technology). We recommend that the leak is re-calibrated once a year and there is a quick disconnect for changing re-certified calibrators.

Features The Spectron 600 portable leak detectors have been designed to provide fast, accurate leak detection from the workshop to the clean-room. The Spectron 600T uses the latest in leak detector technology in an easyto-use, compact form. It can be operated in direct mode for high sensitivity and reverse mode for faster cycle times. The Spectron 600D features an oil-free diaphragm/molecular drag pump for applications which demand 100% dry leak detection. The Spectron 600DS is the 600D in a stainless steel enclosure with HEPA filters designed to conform to the most stringent clean-room standards. The Spectron 600 is a completely self-contained portable leak detector capable of working in a wide range of environments. All that is needed is a suitable electrical supply and a helium source (helium 3 or 4, any quality). When the unit is switched on it performs a self-diagnostic routine and all of the LEDs on the user panel are tested, the foreline area is pumped down and the turbo pump ramps-up to its rated speed. The system is ready to test in less than 5 minutes, with no operator intervention. For a leak detector to give reliable, repeatable results it is essential that it always performs at its optimum. The Spectron 600 incorporates several features designed to make it the most accurate leak detector available.

Mass Spectrometer Two identical magnetic fields (90° sectors) are used in the Spectron 600’s mass spectrometer to make sure that only helium ions reach the ion collector. This is a unique feature which gives the Spectron 600 a resolution (the ability of a mass spectrometer to separate ions of different mass/ charge ratios) of 14 - almost twice that of competing models.
