Multi-function instrument for temperature-humidity-airflow-pressure

High preci­sion data logger for temper­ature (±0.03), relative humidity, dew point, air flow with memory for 6,000 meas­ure­ments. P755B-LOG includes Bluetooth transission for using DE-GraphBlue. The instru­ment is designed for applic­a­tion of the quality assur­ance, e.g. testing climatic cham­bers, calib­ra­tion ther­mo­stats, oven or ther­mo­elec­trical processes. For the battery-powered instru­ment we provide a separate power supply as an option. The meas­uring interval is adjustable between 1 second and 30 minutes. The P755-LOG meas­uring system is the perfect standard to test subor­din­ated instru­ments or systems. For trace­ab­ility we recom­mend to order those instru­ments with a calib­ra­tion certi­ficate.
