The battery for data loggers takes just seconds to install, because it fits perfectly when screwed into the logger. This means you do not need to worry about any damage to the data logger as a result of fitting the battery.
  • Ideal for measurements at low temperatures, e.g. freeze-drying
  • Can be used at temperatures between -50 and +140 °C
  • Service life of 750 operating hours
  • Changing the battery takes just seconds, saving time and increasing efficiency
The practical thread enables the battery to be screwed onto the data logger and changed intuitively and securely without using any tools. This shortens your processes enormously – and after each battery change, the loggers are 100% tight. You do not need to worry about any damage to the data logger when changing the battery either.

The battery consists of a lithium core and the battery housing is coated with a high-temperature-resistant polyether ether ketone (PEEK).
