Recording of temperatures throughout the cold chain is a regulatory requirement for many transported products for example QFF frozen foodstuffs.
Recent revision to ATP requires temperature recorders to be tested to EN12830 and for periodic verification EN 13486.
In the UK and Eire CRT is the designated test station approved by the Department for Transport, for certifying equipment in accordance to ATP and can therefore certify such equipment acceptable to all ATP contracting parties.
