Using interchangeable probes this versatile metre reads airspeed, temperature, RH and light. The user can order probes for the parameters currently required and add additional probes in the future. Intelligent probes electronically retain calibration information. No recalibration is required when changing probes. The display simultaneously reads temperature in user selectable deg. C and deg. F and all measurements are automatically temperature compensated. RS-232 port enables communication with a computer. Also features auto power off, hold and min-max. Fold out easel back and a tripod screw. Comes with 9V battery and a hardshell foam-lined carrying case with room for one or two probes.
