The Q-tag® Quad is a multi-alarm electronic temperature indicator designed for international and national cold chain supply and professional warehousing systems. It allows for up to four independent alarm thresholds (including single-event and cumulative), providing tighter temperature risk control than conventional temperature indicators.
The Q-tag® Quad visually displays OK/ALARM status on the screen, operates simply – no software required – no file output needed, making it suitable for quick point-of-delivery checks and cold chain audits.
