Description
The Additel ADT672-10-AP300-PSI-N is the absolute pressure version of the ADT672 with a range of 0 to 300 psia and 0.1% FS accuracy. It is supplied with a 1/4 in NPT male pressure port. Absolute measurement makes it suited to barometric and absolute transmitter calibration. The Additel ADT672 is a handheld pressure calibrator that combines an internal pressure sensor with electrical measurement and a 24 V loop supply in one instrument. Connected to an external pressure source such as a hand pump, it reads applied pressure while measuring the mA or voltage output of the device under test. Instrument technicians use it to calibrate and troubleshoot pressure transmitters, gauges and switches in the field, in workshops and in calibration labs.
Key features
- Internal pressure sensor in gauge, compound, absolute, vacuum or differential versions
