Overview
The LP+ is a pendulum sensor that hangs from a 5 m cable for measuring CO2 in large rooms such as exhibition halls, factories and museums. It also measures temperature, and can output humidity-derived values where fitted. It has analogue 0 to 10 V (or 0 to 5 V) outputs for connection to a BMS or monitoring system. One version has a colour-changing LCD with threshold indication.
