PC Screenshot of THref RealTime Data DisplaysSeveral THref graphical and numeric realtime data displays are active in this PC screenshot. Each colored curve shows RH or T data from one of the probes as either 1 Hz samples or 1 min averages. Silver curves are the average of the 3 probes from each manufacturer, and black curves are the average of all 6 probes calculated in two different ways (the "best estimate" values). The two graphs on the right show the 1 Hz T data (top) and 1 Hz RH data (bottom) for a 15 min period, and the left graph shows the 1 min average RH data for a 1 hour period. The manufacturers' accuracy specifications for the individual probes are in the range ±0.61.5% RH and ±0.20.25°C. The above data form a band containing all measurements that has a halfwidth of ±0.5% RH and ±0.15°C, which is consistent given the stated accuracy specs. The estimated uncertainty (or absolute accuracy) of the bestestimate values (black), from statistical considerations, is about ±0.5% RH and ±0.1°C.
