OVERVIEW

At 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 improvements and
additional value to the existing line of calibrators (Additel 761 series). The ADT761A
has many improvements: 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, 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 ±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.

Pressure / Process Calibration Equipment

ADT761A-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 precongured with the modules that t 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 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 precongured based

on the variety of modules available down to 10 psig (0.7 bar.g).

ADT761A-1K

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 precongured based on the variety of modules available down to 30 psig (2 bar.g).

02

ADT761A-APXR Precision Accuracy Options

The Additel 761A series includes a precision accuracy option which
provides an accuracy of 0.01%FS. This calibrator option includes a single
non-removable sensor and can measure absolute and gauge pressures.

Model congurations are available from 15 to 1,000 psig (1 to 70 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 eld.
