Temperature logger operates for longer durations

Article By : Maxim Integrated Products

The DS1925 iButton data logger enables monitoring cold chain, as well as temperature logging in pharmaceutical, medical, bio science and food safety applications.

Maxim Integrated Products has introduced the DS1925 iButton data logger that enables monitoring cold chain and other temperature sensitive products or processes for longer duration sessions. The device is also aimed at temperature logging in pharmaceutical, medical, bio science and food safety applications, noted the company.

Temperature sensitive products and processes can be damaged when exposed to temperatures that are too high or too low. Previously, companies could only retrieve 16Kbyte of data for each session of critical temperature monitoring, and would often need to reduce the data sample. With 122Kbyte of data-log memory, the DS1925 claims to provide 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.

According to the company, the device measures 17.35mm x 5.89mm and offers improved accuracy, operating from ±0.5°C over -40°C to 85°C.

Evaluation kits are available with hardware, software, host system source code, accessory products and system solution references.
