The two multi-func­tion-instru­ments are outstanding for theri high accuracy of ±0,1°C. You can optional plug in Pt100 or ther­mo­couple (type J, K, L, N, R, S, T), as well as probes for humidity and flow. The high preci­sion makes them emin­ently suit­able as refer­ence instru­ments for testing subor­dinate meas­uring instru­ments in quality assur­ance labor­at­ories or for checking temper­ature- crit­ical processes. These instru­ments are frequently provided with a DKD calib­ra­tion certi­ficate. The P770B includes Bluetooth transmission for using DE-GraphBlue.

The univer­sally applic­able process-controlled hand-held instru­ments, Series P700, are ideal for meas­uring oper­a­tions in which high accuracy counts or the possib­ility of online docu­ment­a­tion is demanded.
