Differential pressure measuring instrument - testo 526 - 1

Differential pressure measuring instrument Temperature-compensated differential pressure sensor 0 to Additional 2 probe inputs for the connection of further probes for the measurement of pressure and temperature Direct zeroing of display value from pressure probes Display of Hold-, max. and min. values Easy data storage by measurement site as well as analysis, archiving and documentation via optional PC software Leakage rate measurement (pressure drop per time) Testing of pressure drop in containers, pipelines etc. testo 526-1/-2 is a highly precise differential pressure measurng instruemnt with an internal sensor. This has a measuring range from 0 to 2000 hPa. The instrument is optimally suited to pressure checks in sensitive industrial processes, and is available in 2 accuracy classes. - testo 526-1 : accuracy 0.1 % of final value - testo 526-2: accuracy 0.05 % of final value The testo 526-1/-2 additionally has two probe inputs for the connection of further probes for the measurement of pressure and temperature. A large selection of probes is available for this purpose. Specially for the purposes of tightness tests on containers, uninterrrupted recording is possible via the test menu in testo 526-1 and testo 526-2. The subsequent processing of the measurement data via software or printout via the printer allow the documentation of the pressure test.
