The Series BPI is a range of battery powered temperature
indicators. The Series BPI-XX1 accepts an RTD sensor; 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.
