Series BPI/TC Battery Powered Digital Thermometer

Specifications - Installation and Operating Instructions

The Series BPI is a range of battery powered temperature
indicators. The Series BPI-XX2 accepts a thermocouple sensor.
The sensor type, temperature units and other flexible
configuration settings are selectable via a simple to use menu
system, which is navigated by the use of three push-button keys
located on the rear of the display. The entire assembly is sealed
into a cap that fits directly onto the connecting heads.

Please inspect the packaging and instrument thoroughly for any
signs of transit damage. If the instrument has been damaged,
please notify your shipper immediately.

may be fixed directly to the housing, or remotely connected
using cable and gland. Cable length must be no greater than 20
meters to comply with CE certification. All external
cabling/sensor entries must maintain IP67 rating.

) are shown in the diagram
to the left. Pressing 2 buttons
simultaneously causes ENTer

or ESCape actions.

When cycling around menu, the
