Product Description

ERICHSEN Brightness Measuring

Instrument TINT TESTER 527

Purpose and application

 

The TINT TESTER 527, has been developed especially for brightness measurement of dark,

uncured coatings such as paste pigment applications on flat surfaces, to determine the tinting strength

according to ASTM D 3265 and ASTM D 2745. Besides this special application, the instrument can

also be used as a standard reflection photometer to measure the brightness of solid substrates (coatings, paper, plastics, etc.) according to ASTM E 97.

 

Design and function

The TINT TESTER 527 consists of a stationary, mains driven power supply and display unit (with digital

display for a range from 0-199.99) and the portable TINT SENSOR Y degree of resolution.

TINT SENSOR Y:

The TINT Sensor incorporates the 45°/0° worldwide standardized measuring geometry with light source C

illumination. The spectral response of the light sensing photocell is corrected with an especially selected Yfilter so that the measuring values correspond with the brightness sensitivity of the CIE-2°-standard observer. An adjusted and optimized lens system is part of the light transmitting and sensing optics to guarantee homogenous illumination of the specimen surface as well as a defined reception of the remitted light. Because of this, the results of measurement are highly reproducible, free of drift and according to specifications.

The opto-electronic system of the measuring head is insensitive against external disturbances due to the

integrated pre-amplifier. It is possible to set the amplification within a wide range so that the measuring

range of the instrument can be adjusted to the actual measuring problem to get optimum results.

Two transverse support ledges 8 mm wide and at a pitch of 80 mm integrated with the undersides of the

measuring head, keep the measuring head away from the specimen so that measurements on coatings in the form of pastes are possible: the ledges prevent damage to the specimen and contamination of the

measuring head. The gap between the measuring head and the specimen is 0.5 mm. It is thus possible

to measure tint strength of freshly applied coatings with a wet film thickness of approx. 400 μm whilst

extraneous light is totally excluded.
