This standalone data logger measures over 32,000 readings from inter-changeable J, K or T type thermocouples. Supplied with a K Type probe, its measurement range out of the box measures from 0 to 200°C range. At the touch of a button, use the on-board display to cycle between the current, minimum and maximum temperature logs seen during the session. Easily set up the logger and view downloaded data by plugging the unit into a PC’s USB port and using the free EasyLog software provided. Data can then be graphed, printed and exported to other applications for detailed analysis. Supplied with ½ AA battery, K-type probe and wall mount clip.

It's ideal for the monitoring of environmental factors in workshop, warehouse, achieve room, cold storage room, clean room, office and communication machine room.

The DS1923 temperature/humidity logger iButton® is a rugged, self-sufficient system that measures temperature and/or humidity and records the result in a protected memory section. The recording is done at a user-defined rate. A total of 8192 8-bit readings or 4096 16-bit readings taken at equidistant intervals ranging from 1s to 273hrs can be stored. In addition to this, there are 512 bytes of SRAM for storing application-specific information and 64 bytes for calibration data. A mission to collect data can be programmed to begin immediately, or after a userdefined delay or after a temperature alarm. Access to the memory and control functions can be passwordprotected.   The DS1923 is configured and communicates with a host-computing device through the serial 1-Wire protocol, which requires only a single data lead and a ground return. Every DS1923 is factory-lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel package is highly resistant to environmental hazards such as dirt, moisture, and shock. Accessories permit the DS1923 to be mounted on almost any object, including containers, pallets and bags.
