Part of the Additel ADT761A series, the ADT 761A-LLP comes with a ±30 inH2O (±75 mbar) high range module and a low range module of your choice ranging from ±20 inH2O to as low as ±0.25 inH2O (±50 to ±0.62 mbar). The ADT 761A-LLP is designed for low pressure calibration and has an accuracy of 0.05%FS with control stability better than 0.005%FS. The measurements can be made in differential or gauge pressures.
