P755-LOG multi-function instrument for temperature-humidity-airflow-pressure - Dostmann

High preci­sion data logger for temper­ature (±0,03), relative humidity, dew point, air flow with memory for 6.000 meas­ure­ments. 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. By using our preci­sion Pt100-probes with sensor calib­ra­tion code you will reach the on page 12 descripted system accuracy. 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.
