Cooper-Atkins' TempTrak Enterprise Wireless Monitoring now offers transmitters and probes for the federally funded Vaccines for Children (VFC) program. The VFC program provides vaccines at no cost to children who might not be vaccinated due to inability to pay. The use of TempTrak's VFC transmitters and probes addresses the CDC's recommendation that the accuracy of equipment where vaccines are stored must be measured using temperature-monitoring devices that are calibrated and traceable to either an ISO/IEC7025 accredited testing laboratory, NIST, or to another internationally recognized standards agency.
