TOUCH SCREEN
(-CRT AND -BRT MODELS)
The optional backlit touch screen interface
mounted in the lid of the electronics module
provides a large, bright display of the measured
temperature, as well as controls allowing full
configuration of the sensor. The graph view
shows the history of the measured temperature.
In alarm conditions, the display changes colour
to provide an immediate and obvious alarm
indication. Alarm modes and levels can be
configured via the touch screen.

DATA LOGGING (-CRT AND -BRT MODELS)
The PyroMini can be used as a standalone data logger.
PyroMini models -CRT and -BRT include a MicroSD card slot for data logging, which can be
configured via the touch screen interface. The user can select the sample rate and the number of
samples to be taken and schedule the data logging to start at a certain time.
With a 2 GB card, the user can store 28.4 million readings, which provides almost 1 year’s worth of
data at the fastest possible sample rate of 1 per second.
Data is stored on the MicroSD card in .csv format and can be viewed and edited easily using
spreadsheet software. Alarm events can also be logged to the MicroSD Card.
A MicroSD card with SD card adapter is available as an optional accessory.
The MicroSD card slot and battery holder are located on the touch screen circuit board in the lid of
the PyroMini. Readings are time and date stamped using the sensor’s internal clock. The clock is
reset when the power is disconnected, or it will continue if the optional battery is fitted.
