Oerlikon Leybold Vacuum has introduced the new LEYCON Valve Program with improved flexibility. LEYCON Valves are available as ISO-KF angle and straight-through valves. All types are bellows-sealed and available in two materials for housing, in either aluminium or stainless steel. There is the choice of hand or pneumatic operation, as well as electro-pneumatical or electro-magnetical actuation. For further information see www.oerlikon.com.
SEDI Fibres Optiques now offers comprehensive solutions for fibre-optic hermetic feed throughs. These are associated with connectors: FC for single-mode or graded-index fibres; SMA for large-core fibres from 140 μm to 1000 μm; ST connectors for all types of silica fibres from 140 μm to 1000 μm; and FC/APC for single-mode fibres.

Hamamatsu Photonics has introduced new high-sensitivity photomultipliers. The super bialkali (SBA) tubes offer 35% quantum efficiency (QE) and the ultra bialkali tubes have up to 45% QE. This QE is close to that of many semiconductor sensors. For further information, tel +44 170 729 4888; e-mail Europe@hamamatsu.com or see www.sales.hamamatsu.com.
Agilent Technologies Inc has introduced the first time-to-digital converter from its Acqiris product line. The TC890 records multiple events or hits on each of its six input channels, with a timing-resolution of 50 ps and a double pulse resolution of less than 15 ns. At full speed, it offers a data throughput of 25 million events/s. Six of the seven identical input channels are independent stop inputs, and the seventh is the common start. For more information see www.agilent.com/find/acqiris.
Metrum Information Storage offers a new cost-effective portable thermal-imaging camera. The Thermo Tracer TH9260 is hand-held and features a 1.3 megapixel digital camera. Multi-point measurement can be made over the 640 × 480 array of pixels using a comprehensive set of dynamic analysis tools over a wide range of temperatures from –40 to +500 °C standard, or 100–2000 °C. Contact Scott Foster, tel +44 118 973 3000; or e-mail thermography@metrum.co.uk.
Pfeiffer Vacuum has expanded its series of DigiLine vacuum instruments with the new MPT 100 transmitter. The combination of a Pirani and a cold cathode sensor is compatible with existing controllers and accessories, giving a measurement range from 5 × 10–9 to 1000 mbar and insensitivity to gas inrush. The MPT 100 can easily be combined with Pfeiffer Vacuum backing-pumps, turbopumps or leak detectors via the RS-485 interface. For further information, see www.pfeiffer-vacuum.net.
ETL has launched a new, portable high-accuracy barometric-pressure measuring unit. The 765–16B gives barometric-pressure readings of ±0.08 hPa with a resolution of 0.0001%. An internal logger can automatically store more than 390,000 high-resolution data points. For further information, contact Derek Nobe, tel +44 178 447 2130; or e-mail sales@explorocean.com.
New technology developed jointly between Southern Scientific and the UK National Physical Laboratory has been incorporated into a compact electrometer module board to measure very small currents with extremely high precision and repeatability. The PAM pico-ammeter is an auto-ranging, microprocessor-controlled, single-board, low-current measurement instrument. It measures currents from 10 fA to 200 nA with a typical accuracy of ±1%, a stability of < 50 fA and linearity of ±1%.
