The portable MP Surveyor II provides instantaneous monitoring for all IAQ parameters, says the manufacturer. Features of the product include a “smart” four-function NDIR probe (Co, CO2, temperature, and rh), dual sockets, and continuous datalogging. Optional “smart” probes are available, designed to provide measures of pressure, velocity, volume flow, rpm, particulates, and airspeed.
