Monochromatic lights have a low pressure sodium light source that emits monochromatic light in which rays have virtually the same wavelength. This light is a very effective way of viewing fringe patterns on the surface of optical flats (Newton rings) Knight Optical's standard type moonlight has a straight line engraved across the diffused screen enabling the operator to easily compare the straight lines of the component being tested thus identifying how flat the flatness is. Other options of monochromatic lights are available enhanced version and floor standing version. These lights are not supplied with the optical flat as standard however we stock a range of quartz and Zerodur optical flats with a range of flatness’s to meet your application. Monochromatic light units are suitable for the following electrical services: 220/240V, 110V and 12VDC on selected units. Contact our technical team for further information. FOR MORE INFO READ PDF…

Heavy Duty Hand Compressor Made to Last. For 400gr. Cartridges or 500 gr. Bulk Fill. Cast Iron Head fitted with Filler Nipple/Air Release Valve. Short Stroke delivery system.

For anyone intending to carry out routine maintenance to critical pressurisation units, the 12377 is an essential tool. Weighing approximately 30kg this unit is fully portable. Its design incorporates wheels, and an extendable handle to aid its movement. Following a recent design change to incorporate the same 1/3HP compressor that is used in the 12434, and 12437, this small unit is now able to produce a dry air output of 30 cubic feet per hour at output pressures of between 3 and 15 psi. Should increase flow be required a unique feature allows a second compressor to be connected to a built-in power take off point. Each 12377 is supplied ready to run, complete with 3 metre power lead and plug, and a quick connect chuck for pneumatic connection. Uses twin tower molecular sieve, adsorption system.

With more than 35 years of experience, CINTROPUR® has built its reputation on quality products in the water filtration business designing a wide range of centrifugal filters for clean water (fittings from ¾’’ to 3’’. Flow rates from 1 to 50 m3/h). Cintropur® water filters are intended for domestic and industrial water system filtration. As well as rain, spring or well water recovery and treatment they are also suitable for watering and irrigation. Cintropur® performs either a mechanical filtration of particles, a chemical filtration through activated carbon absorption, or sterilizes water by ultraviolet radiation of UV-C type. CINTROPUR® offers a double-stage of filtration concept. First, the water flow from the inlet is directly transformed into a centrifugal spin forcing the larger particles down into the lower bowl. The next stage of filtration is achieved by the exclusive filter sleeve, available in different finenesses ranging from 5 up to 300µ.
