TFT DIGITAL OBA METER

• A portable meter for measuring fluorescence of textiles and flat materials or surfaces

• It is hand held and self contained with integral rechargeable batteries

• The clear digital read out incorporates a battery low indicator and the charger is

included in the kit

• The whole system is supplied in a padded 'attache style' carrying case

• A fluorescent reference paper based on Ciba-Geigy Reference Tile 12 as 100 units is

provided for routine user recalibration

Applications

• Precise measurement of fluorescence of textiles, paper and other materials for quality

control purposes

• Designed for use in routine monitoring of OBA application levels

• Used in the laundry and drycleaning industry to measure loss of brightness to monitor process control

• Used in conjunction with the TFT Digital Reflectometer to differentiate between loss

of brightness and redeposition of particulate soil during cleansing, and to quantify

these changes.

• A portable meter for measuring reflectance of textiles and flat materials or surfaces

• It is hand held and self contained with integral rechargeable batteries

• The clear digital read out incorporates a battery low indicator and the charger is included in the kit

• A certified white reference tile is provided for routine user recalibration

• The whole system is supplied in a padded 'attache style' carrying case

• The optical geometry produces results comparable to the null type (moving coil meter) reflectometers used by the laundry industry without the temperature instability problems of some of the older designs.

Applications

• Precise measurement of reflectance of white textiles for quality control purposes

• Designed for use in monitoring reflectance to NHS contract standards

• Used in the drycleaning and laundry industry to indicate the different levels of greying produced under various process conditions

• Used to measure soil removal levels from EMPA soiled test fabrics

• Used in conjunction with the TFT OBA Meter, it is possible to differentiate between loss of brightness and redeposition of particulate soil during cleansing and to quantify these changes.
