The DR-40GSM temperature recorder measures temperature in four places simultaneously. Each measurement path has its own sensor with the possibility of extending it up to 80m (using a cable of appropriate thickness). The device has alarm signaling for each sensor in the form of SMS messages about exceeded maximum and minimum values. It records the measured temperatures through the built-in USB port and a portable memory connected to the port. To read the memory, connect the flash drive to the computer and open the file in Excel or Openoffice calc.

After exceeding the set temperature by one of the sensors, the user will receive a message with information about the exceeded MIN or MAX alarm, the current temperature and the time of the alarm. Each user has the option of sending an SMS message with the text Info. In confirmation, he receives an SMS message with information about the current temperatures measured by the sensors.

The recorder has a sound buzzer that is activated when the alarm is activated.

The DR-40GSM recorder has a relay alarm output, NO-normally open or NC-normally closed, the function is set in the menu.
