Rhopoint Instruments manufacturing and office in St Leonards on Sea, East Sussex,

Who we are

Rhopoint Instruments is a UK based manufacturer of test equipment primarily focused towards appearance quality and is a subsidiary of Rhopoint Holdings. Rhopoint Instruments was founded in 1988 as a manufacturer of glossmeters. Since this time, the range has developed and grown to test not just gloss but many other parameters of total surface quality including orange peel / DOI, haze, texture, defect analysis, and shade and opacity.

What we do

Our handheld instruments are designed to be used in both research and development and production environments in numerous industries including: paints and coatings, automotive, yacht manufacturers, metal polishers, polished stone, smart phone, tablet PC and laptop covers, coil coaters, printing and graphic arts, powder coating, furniture, and plastics. The Rhopoint MFFT –Minimum Film Forming Temperature measuring instrument is trusted by laboratory professionals in the leading global coatings manufacturers for measuring the temperature point of coalescence of a latex, emulsion or adhesive.

In 2006 Rhopoint Instruments acquired the Hanatek range of packaging test equipment testing many parameters in order to provide manufacturers and users of packaging material with consistently faster packaging speeds. In 2013 Rhopoint Instruments launched the Optimap PSD which marks a revolution in the control of surface quality. For the first time subjective visual assessment can be replaced with reliable, representative measurement. The Optimap™ is the first portable instrument to map and measure surface texture. Surface texture is used to quantify visible faults such as orange peel, waviness and DOI problems. It can also be used to identify local faults such as inclusions, pinholes, runs, sags, blisters etc.

In a single fast operation the Optimap™ maps the topography of a test surface displaying faults and texture in incredible detail. Mapped information is processed into objective surface measurements that can be used to effectively control product quality. variety of surfaces: semi matt surfaces to polished mirrors, small & curved parts.

Rhopoint Instruments is part of the Rhopoint group of companies all of which operate to ISO 9001:2015 Quality Management Systems. Other subsidiaries include:

History of Rhopoint

Rhopoint Ltd was founded in 1975 with the aim to support engineers specialising in the design of electronics and product development by offering a selection of precision resistors to the UK market.

The Rhopoint name originates from two ideas. Firstly, the Greek letter ρ (pronounced rho). This is the symbol that represent electrical resistivity; the fundamental property of a material that quantifies how strongly it resists or conducts electrical current.

Secondly the word “point”, in the context of measurement, is defined as a definite measurable position in a scale, thereby signifying precision.

Hence the company was named Rhopoint to highlight our competence in the ever-evolving world of precision resistors. Incidentally, the first product sold in 1975 was a high-precision wire-wound resistor from General Resistance. These products still represent part of the Rhopoint Components Ltd. portfolio today, over 45 years later!

In 1986, Rhopoint Ltd. acquired their customer Startronic, a manufacturer of testing products for the Paint & Coatings industry. Startronic was then renamed Rhopoint Instrumentation Ltd. to which the business remains today as Rhopoint Instruments Ltd. We have since acquired the Hanatek range of packaging test equipment as well as introducing a number of new product lines to market.
