Total Appear­ance Con­trol -
color and gloss in one unit

The over­all appear­ance of a prod­uct is influ­enced by color and gloss. A sam­ple of the same color but higher gloss level is visu­ally per­ceived darker and more sat­u­rated than a low gloss sam­ple. In order to get a uni­form appear­ance, both attributes need to be con­trolled. The spec­tro-guide spec­tropho­tome­ter is unique as it mea­sures both attributes simul­ta­ne­ously. Thus, the cause of a mis­match can be clearly defined in any sit­u­a­tion.

• Color (45/0 or sphere) and 60° gloss are dis­played at the same time
• In com­pliance with inter­na­tio­nal spe­c­i­fi­ca­tions
• Tol­er­ances for color and gloss allow quick pass/fail deci­sions in pro­duc­tion

Easy to use and han­dle

The spec­tro-guide spec­tropho­tome­ter makes qual­ity con­trol sim­ple and secure - even for color begin­n­ers. Thanks to the intu­i­tive pull­down menu and the four-cur­sor but­ton oper­a­tion, qual­ity con­trol has never been easier.

• Light weight and small size - weighs only 500 g
• Ergo­nomic design - can eas­ily mea­sure dif­fi­cult to access areas
• Desig­nated but­tons for stan­dard and sam­ple read­ings
• Cus­tomiza­tion of the dis­play to your needs

True cir­cum­fer­en­tial illu­mi­na­tion for best repeata­bil­ity on tex­tured sam­ples.

Highly repeat­able on tex­tured
sur­faces

The key cri­te­rion for a 45/0 instru­ment is a cir­cum­fer­en­tial
illu­mi­na­tion. spec­tro-guide 45/0 is using a unique, patented mea­sure­ment prin­ci­ple to achieve a 100% cir­cum­fer­en­tial
illu­mi­na­tion. A white coated hemi­sphere acts as a mix­ing cham­ber and guar­an­tees com­pletely uni­form illu­mi­na­tion. Thus, any influ­ence of mea­sure­ment direc­tion is elim­i­nated and excel­lent repeata­bil­ity even on highly tex­tured sur­faces is guar­an­teed.

45° Illu­mi­na­tion

Always ready to use

Eco­nom­i­cal and reli­able oper­a­tion of a spec­tropho­tome­ter is often taken as given. spec­tro-guide guar­an­tees supe­rior
accu­racy for many years and low main­te­nance efforts.

• Long last­ing stan­dard AA bat­teries - up to 8,000 read­ings per set
• 10 year war­ranty on the light source - no lamp changes needed
• Rugged and com­pact design
• Sta­ble, long-term cal­i­bra­tion - needed only every three months

Always pre­cise color val­ues

With the new spec­tro-guide spec­tropho­tome­ter you can
mea­sure any color: dark - bril­liant - steep reflec­tance curves.
The 10 nm spec­tral res­o­lu­tion not only ensures highly pre­cise color results, but also an excel­lent agree­ment with com­pet­i­tive color instru­ments - even bench-top units.

Addi­tio­n­ally, a patented illu­mi­na­tion con­trol pro­vides tem­per­a­ture inde­pen­dent results - even in extreme con­di­tions.

Pro­fes­sio­nal Doc­u­men­ta­tion
with easy-link

No mat­ter whether you want to com­pare a batch to a defined stan­dard or mon­i­tor pro­cess changes over time, easy-link, included with spec­tro-guide, offers all of the neces­sary tools. Direct data trans­fer from the spec­tropho­tome­ter into
pre­defined QC tem­plates makes you ready for rou­tine color con­trol.

The micro-TRI-gloss also trans­fers gloss val­ues to easy-link, see page 24.

The CIE­Lab-Graph charts dif­fer­ences in color and light­ness together with pro­duc­tion tol­er­ances.

Is pro­duc­tion sta­ble over time?
All data are sum­marized in a trend graph: Color, gloss, film thick­ness and your own prod­uct spe­cific infor­ma­tion.

Color and Gloss Con­trol
of auto­mo­tive inte­rior parts

Most peo­ple con­sider color and gloss har­mony of the car
inte­rior to be a key item when judg­ing the per­ceived qual­ity of a vehi­cle. Conse­quently, the qual­ity require­ments for the
inte­rior design of a car have increased over the last years. A vari­ety of mate­rials are used and need to be har­monized. To achieve a uni­form look among the inte­rior trim parts, very tight tol­er­ances are spe­c­i­fied. Only instru­ments with excel­lent pre­ci­sion are able to objec­tively con­trol the pro­duc­tion.

The new spec­tro-guide S fam­ily offers improved tech­ni­cal
per­for­mance for 60° gloss in the low gloss range 0 - 10 GU. The excel­lent repeata­bil­ity of ± 0.1 can be guar­an­teed due to a patented cal­i­bra­tion pro­ce­dure.

In addi­tion, the spec­tro-guide S spec­tropho­tome­ter offers unique ben­e­fits to always guar­an­tee pre­cise results:

• Highly repeat­able results inde­pen­dent of mea­sur­ing
  direc­tion due to a patented, true cir­cum­fer­en­tial illu­mi­na­tion
• Long-term sta­ble cal­i­bra­tion - needed only every three months
• Tem­per­a­ture sta­ble color and gloss data between 10 - 40°C
• 10 year war­ranty on the light source
• 10 nm res­o­lu­tion for pre­cise read­ings on bril­liant and dark col­ors
• Pro­fes­sio­nal doc­u­men­ta­tion with easy-link soft­ware
