Sper 850071 Environmental Meter for Air Flow, Temperature, %RH and Light
Interchangeable Probes

SPER 850071 ENVIRONMENTAL QUALITY METER

Using interchangeable probes this versatile meter reads airspeed, temperature, %RH, and light. The user can order probes for only 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 ºC & ºF and all measurements are automatically temperature compensated.

RS-232 port enables communication with a computer.

Features include 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.

Dim: (main unit): 7¾" x 2½" x 1" (195 x 68 x 30mm).

Weight: (main unit): 8.8oz (250g).
