The Polwax PTRANS TD90 is an ultra-compact, single-use temperature data logger specifically designed for monitoring temperature-sensitive products during transportation and storage. With a wide measurement range of -90°C to +70°C, the PTRANS TD90 is particularly suitable for dry ice shipments and other applications where reliable monitoring at ultra-low temperatures is essential. It provides accurate, continuous temperature recording to help maintain product integrity throughout the cold chain.
The PTRANS TD90 is developed for critical cold-chain applications where temperature excursions can affect product quality, safety, and usability. It can be used for monitoring pharmaceuticals, vaccines, biotechnology samples, medical devices, perishable goods, and other temperature-sensitive products during transportation and storage. By maintaining a detailed record of temperature conditions throughout the shipment journey, the logger helps users verify that products have remained within their specified environmental conditions. 
Designed with simplicity and efficiency in mind, the PTRANS TD90 provides a pre-programmed, user-friendly monitoring solution. The device uses a manual start mechanism, allowing users to begin recording when the shipment is ready. Once activated, the logger records temperature data according to the configured logging interval. The logging interval can be configured from 1 minute to 24 hours, with a default setting of 5 minutes, allowing the device to capture detailed temperature history throughout the monitoring period.
The logger provides substantial storage capacity, with memory for up to 33,000 temperature readings. This allows users to maintain a detailed record of temperature conditions throughout a shipment or monitoring period.
