The tempmate-M1 can be instantly used to measure and record your temperature sensitive consignments. The PDF report created contains detailed information in graphical and tabular formats. The tempamte-M1 is powered by a user replaceable CR2032 battery.

With the optional free available tempbase software, you can ensure individual logger configuration and detailed data analysis or data management is also possible. In addition, the tempmate-M1 is exempt from IATAs Dangerous Goods Regulations and is therefore, a perfect solution for use in air freight logistics.

GDP and BS EN 12830 Compliant.

Although software is not always required, the tempbase sofware, used for configuration and data analysis can be downloaded from here: Download tempbase software 

If you chose not to use the configuration software, the following default parameters are used:

  • 15 minute logging interval (sample rate)
  • No start delay
  • No alarms
  • Start by button (press left hand but for 5 seconds to start logging)
  • Stop by button (press right hand button for 5 seconds to stp logging)

Each M1-A data logger is supplied with a UKAS traceable calibration certificate. If you choose an external sensor, once calibrated, the sensor and data logger must stay as a matched pair.

The default calibration points are -25°C, +4°C and +25°C. You can choose any three over the operating range of the logger but there must be more than 20°C  between the highest and lowest point. Please email once you have placed your order if you would like different calibration points.

There is the option of an external sensor probe or wall bracket (images below), at an extra cost. The tempmate-M1 is available ex-stock and can be dispatched the same working day if the order is received by 12 noon.
