THE 540 series of digital comparators, from WIKA Australia, form a family of accurate comparator instruments for use in gas or oil, suited to the workshop environment.
They provide a complete pressure measurement solution, including generation, control and measurement of pressure as well as reading the output signals from the instruments under test.
A comprehensive range of comparators for pneumatic (model 550C), oil (model 580C) or water (model 580CW) operation complements the WIKA 540 series, which provide a cost effective and straightforward solution to many calibration applications.
WIKA comparators can easily be upgraded into deadweight testers by replacing the device under test mounting stand, with a piston cylinder and weight set arrangement.
The 540 series feature a high 0.025% accuracy and have ranges from -0.1 to 10MPa gas, and from 0 to 120MPa oil.
The units are supplied with a complete software package and operate with rechargeable batteries or power supply.
