Rayleigh Instruments - Customer Service

Rayleigh Instruments places the highest priority on customer service, and recognises the importance of fast delivery to its customers.

To this end, Rayleigh holds substantial stocks of standard products. The stock holding is supported by Rayleigh's purpose built Modification Centre which enables many non-standard product options to be supplied with the minimum delay.


If you would like to place an order other than through the Checkout on this site, Orders may be faxed, e-mailed, posted or given verbally to the internal sales department. Rayleigh Instruments will endeavour to process new orders as swiftly and efficiently as possible. Clients are able to greatly assist this process by contributing the following information at the time of order placement:-

  • A full technical specification. The required information is shown on the various pages of our catalogues.
  • If the order is in response to a Rayleigh Quotation please state the Quotation Number.
  • Please quote your credit account number.
