Additel releases Additel 761A series of calibrators

September 9, 2019 - Additel released the Additel 761A series calibrators, designed as an improvement to the existing line of calibrators (Additel 761 series). The ADT761A features: increased pressure range to 1,000 psi (70 bar), removable internal pressure modules, optional precision models to 0.01%FS, increased speed to pressure, ability to read two external pressure modules, touch screen display, WiFi, Bluetooth, and Ethernet communications and double the original battery life.

Just like the first generation, this second-generation product is self-contained and automated with a built-in pump for pressure generation and precision control technology.

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 the user’s choice ranging from ±20 inH2O to as low as ±0.25 inH2O (±50 to ±0.62 mbar). The accuracy of the LLP version is 0.05%FS with a control stability better than 0.005%FS. All measurements can be made in differential or gauge pressures.

The Additel 761A-D also provides differential and gauge measurement while covering a 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 choice covering from as low as ±10 inH2O (25 mbar). Each ADT761A-D can be preconfigured with the modules that fit users’ needs.

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 (-13 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).

The Additel 761A-1K will generate and control from vacuum pressures up to 1,000 psig (70 bar.g). This unit can typically achieve 1,000 psi in less than 45 seconds. 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

(-13 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).

The Additel 761A series has a precision accuracy option which provides an accuracy of 0.01%FS of a fixed internal sensor. This calibrator option includes a single non-removable sensor and can measure absolute and gauge pressures. Model configurations are available from 15 psig (1 bar.g) to 1,000 psig (7 bar.g).

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 suitable for calibration on the bench or in the field.
