Ultra-low pressure calibration pumps from Additel, including hand-held and portable pressure calibrators, and low pressure test pumps, provide an
accurate, reliable, and economic solution for a wide range of pressure applications.
The ADT760-LLP is designed for low pressure calibration and comes with a built-in pressure module to ±30 inH2O (±75 mbar) and provides an accuracy to 0.05%FS (see ordering information for configurations with the option of the ADT760 and a module of your choice). Additional internal pressure modules (ADT155 series) are available and provide a variety of ranges down to ±0.25 inH2O (±0.62 mbar). The accuracy of 0.05%FS and control stability 0.005%FS is based on the internal module’s span. Measurements can be made in gauge or differential mode.
