Model 42270: Temperature and Humidity Datalogging Module
Model 42260: Temperature-only Datalogging Module
The Datalogging modules can be used to monitor the temperature of greenhouses,
warehouses, food transports, aircraft cabins, refrigerated trucks, containers, museums,
and HVAC equipment. The Model 42270 records Relative Humidity readings in addition
to temperature readings. Modules can store 16,000 (8000 temperature and 8000 %RH
for 42270) readings that can later be transferred to PC or directly printed using the Model
42276 Programmer/Printer (covered in a separate manual). Careful use of this device
will provide years of reliable service.
The datalogger display will not switch on until
activated through the software.
The datalogger module display will not switch on until it is activated by the software in the
LOGGER SET menu as described later in this manual. In LOGGER SET the user selects
the type of recording activation. When the logger begins to log data, the display and status
LEDs will switch on.
