Temperature logger 'button' combines long record length & sample rate

June 07, 2016 // By Graham Prophet
Maxim Integrated’s rugged DS1925 iButton temperature logger has been designed for monitoring cold chain and other temperature sensitive products or processes; longer duration sessions is now possible.

Previously, companies could only retrieve 16 kB of data for each session of critical temperature monitoring, and would often need to reduce the data sample. With 122 kB of data-log memory, the DS1925 provides longer monitoring sessions compared to other data log products, while maintaining the desired sample rate.

 

The DS1925 delivers high accuracy over a wide temperature range, and can measure battery life. It also retains measurements even if the battery life ends before the logger is replaced. While other temperature loggers have plastic covers, the DS1925 is made with a durable stainless steel enclosure to withstand harsh environments and conditions. The DS1925 is intended for temperature logging in cold chain, pharmaceutical, medical, bio science, and food safety applications. It offers improved accuracy over the widest temperature range: ±0.5C over -40C to +85C in a package 17.35mm (diameter) x 5.89mm (thickness).

Evaluation kits are available with hardware, software, host system source code, accessory products, and system solution references; pricing starts at $45.25 (1,000).
