Maxim Integrated Products introduces the DS1925 iButton® data logger, enabling longer-term monitoring of cold chains and other temperature-sensitive products or processes.

Temperature-sensitive products or processes can be destroyed if exposed to too high or too low temperatures, and data loggers can help solve this problem. In the past, companies could only retain 16KB of data per critical temperature monitoring task and often had to reduce the data sampling rate. The DS1925 has 122KB of data logging memory, which enables longer monitoring times than other data logging products, while maintaining a corresponding sampling rate.

The DS1925 has high accuracy over a wide temperature range and is capable of measuring battery life. The device retains measurement data even if the battery is depleted before the logger is replaced. Unlike other temperature loggers that use plastic housings, the DS1925 features a rugged stainless steel housing that can withstand harsh environments and conditions. The DS1925 is ideal for temperature recording in cold chain, pharmaceutical, medical, life science, and food safety applications.
