DATA INDUSTRIAL RED

Bright Dyes
Industrial Red products are specially formulated
versions of Rhodamine B, one of the traditional
fluorescent water tracing and leak detection
materials. It may be detected visually, by
ultraviolet light and by appropriate fluorometric
equipment. Visually the dye appears as a bright
dark red to magenta, depending on its concentration
and under ultraviolet light as a bright
orange.
Compared to
Bright Dyes FLT Yellow/Green or FWT Red products,
Industrial Red is significantly less resistant to
absorption on inorganic and organic suspended
matter. Thereby limiting its suitability in many
applications, particularly where fluorometric
detection is needed. This dye has greater
resistance to sunlight than FLT Yellow/Green and is
equivalent to FWT Red. Industrial Red products
should not be used: 1) In drinking water systems,
near drinking water intakes or where downstream
impingement on a drinking water system might occur,
or 2) Where any aquatic ecosystem might be
chronically exposed to detectable amounts of the
dye. The use and suitability of these products
should be evaluated by a qualified hydrologist or
other industry professional.
