Datasheet

The tolerance on all our products is ±1°C of the rated temperature, with the exception of the medical
products (forehead thermometers and drug test strips) that have a tolerance of ±0.5°C of the rated
temperature
It should be noted that for forehead, drug test and wine thermometers an “offset” is applied to the rated
temperature. The “offset” allows for the difference in temperature readings between the outside and inside
of a host item. For example the surface skin temperature of a human is lower than the core body
temperature due to heat loss from the surface. A great amount of research has been carried out on this
subject to ensure the correct offset has been assigned.
Reading TLC Thermometers:
The correct temperature is indicated by the square on the TLC thermometer that turns green. If green is
not visible the temperature will be mid way between the indicators that are illuminated tan and blue as
follows:
Indicator is just above the Actual Temperature Reading
Indicator is the Actual Temperature Reading
Indicator is just below the Actual Temperature Reading
Please note the above colours are a guide for demonstrative purposes and the actual colours observed could be slightly
different depending on label type.
Generally liquid crystal thermometer strips / temperature indicators can be read accurately to within half
the increment between adjacent temperature events. For example the A296 series products, which have
events sequenced every 5ºC, the temperature can be read to within 2.5ºC. For A523 series where events
are sequenced every 1ºC or 2ºC and medical products (including forehead and drug test strips) the
temperature can be read to within 0.5ºC and 1ºC respectively.
Custom Products:
In addition to the standard Liquid Crystal labels available, which cover the temperature range of -30 -
120°C, a full custom manufacturing service is available and products can be manufactured to meet
customers' precise requirements of, for example, size, shape, colour, temperature range, number of
temperature elements, graphic printing (logo's etc). Please ask for details.
