DatasheetAt Additel, innovation and continuous improvement are part of our company’s culture and the products we introduce. When we set out to deliver the Additel 761A series calibrators, we knew we needed to provide breakthrough additional value to the existing line of calibrators (Additel 761 series).
The 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.
