The Additel ADT260EX-BP has the same features as the ADT260EX but instead of measuring in gauge pressure ranges it measures in barometric pressure ranges. 

Functional Features
RTD Measurement 2, 3, or 4 wire (user selectable). Unit measurement as °C, °F, K or ohms.
Filtering Average sliding filter (sample 1 ~ 50) First-order linear filter (coefficient: 0.01 ~ 1)
Switch The measurement value will be automatically displayed at the moment the switch changes state. The latest 8 state changes will be stored in the memory.
Pressure Tare Tare value is set through the user interface
Pressure Stability Indicator Stability time and criteria is selectable
Power Management Backlight auto off, Auto power off
