DatasheetThe ADT761A has many improvements: increased pressure range to 70 bar (1,000 psi), removable internal pressure modules, optional precision models up to 0.01% of Span, increased speed to pressure, ability to read two external pressure modules, touch screen display, Wi-Fi, Bluetooth, and Ethernet communications, double the original battery life, and more! Just like the first generation, this second generation product is completely selfcontained and automated with a built-in pump for pressure generation and precision control technology. Simply set the desired pressure and watch the calibrator do the work.
ADT761A-LLP
The Additel 761A-LLP is designed for low pressure calibration and comes with a ±75 mbar (±30 inH2O) high range module and a low range module of your choice ranging from ±50 to as low as ±0.62 mbar (±20 inH2O to ±0.25 inH2O). This unit has an accuracy of 0.05% of Span with control stability better than 0.005% of Span. All measurements can be made in differential or gauge pressures.
ADT761A-D
The Additel 761A-D also provides differential and gauge measurement which covers the range of
-0.95 to 2.5 bar (-13.5 to 35 psi). This unit comes with a CP35 module (-0.95 to 2.5 bar) and one low range module of your choice ranging as low as 25 mbar (±10 inH2O). 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.
ADT761A-500
The Additel 761A-500 will generate and control from vacuum pressures up to 35 barg (500 psig). Both gauge and absolute pressures can be realized due to a built-in barometer. Each unit comes with a CP500 module (-13 to 500 psig) for the high range and the low range can be preconfigured based on the variety of modules available down to 0.7 barg (10 psig).
ADT761A-1K
The Additel 761A-1K will quickly generate and control from vacuum pressures up to 70 barg (1,000 psig). 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 (-0.9 to 70 barg) for the high range and the low range can be preconfigured based on the variety of modules available down to 2 barg (30 psig).
The Additel 761A series includes a precision accuracy option which provides an accuracy of 0.01% of Span. This calibrator option includes a single non-removable sensor and can measure absolute and gauge pressures. Model configurations are available from 1 to 70 barg (15 to 1,000 psig)
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% of Full Scale, this unit is ideal for calibration on the bench or in the field.
