Description Additel ADT 761A Series Automated Pressure Calibrator. Automated and self-contained pressure generation and control to 1,000 psi ( 70 bar) Standard accuracy to 0.02%FS Two removable internal pressure modules for multi-range selection Control stability to 0.003%FS Portable, designed for use in the field and in the lab Ability to measure two external pressure modules Wi-Fi, LAN, Bluetooth, USB and Ethernet communication Full HART field communicator HART and profibus communication Data logging and task management Patented electric pump technology and improved sp Available Model : Additel ADT 761A-LLP The Additel 761A-LLP is designed for low pressure calibration and 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). This unit has an accuracy of 0.05%FS with control stability better than 0.005%FS. All measurements can be made in differential or gauge pressures. Additel ADT 761A-D The Additel 761A-D also provides differential and gauge measurement which covers the range of -13.5 to 35 psi (-0.95 to 2.5 bar). This unit comes with a CP35 module (-13.5 to 35 psi) and one low range module of your choice rangeing as low as ±10 inH2O (25 mbar). Each ADT761A-D can be preconfigured with the modules that fit your need to give you the best precision at the pressures you perform calibrations. Additel ADT 761A-500 The Additel 761A-500 will generate and control from vacuum pressures up to 500 psig (35 bar.g). Both gauge and absolute pressures can be realized due to a built-in barometer. Each unit comes with a CP500 module (-12.5 to 500 psig) for the high range and the low range can be preconfigured based on the variety of modules available down to 10 psig (0.7 bar.g). ADT761A-1K The Additel 761A-1K will quickly generate and control from vacuum pressures up to 1,000 psig (70 bar.g).  Like the ADT761A-500, both gauge and absolute pressures can be realized due to a built-in barometer. Each unit comes with a CP1K module (-12.5 to 1,000 psig) for the high range and the low range can be preconfigured based on the variety of modules available down to 30 psig (2 bar.g). ADT761A-BP The Additel 761A-BP is designed for calibration of barometer sensors. With a range of 100 to 1200 hPa and an accuracy of 0.01%FS, this unit is ideal for calibration on the bench or in the field.
