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 1,500 psi (100 bar), removable internal
pressure modules, precision accuracy models available to 0.01%FS, increased speed
to pressure, ability to read two external pressure modules, touch screen display, Wi-Fi,
LAN, Bluetooth, and Ethernet communications, double the original battery life, and more!
Just like the rst generation, this second generation product is completely self-contained
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.
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 ranging 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.
ADT761A-1K
The Additel 761A-1K will 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 (-13.5 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)
.
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.
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-1.5K
The Additel 761A-1.5K will generate and control from vacuum pressures up
to 1,500 psig (100 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 CP1.5K module (-13.5 to 1,500 psig) for the high range and the low range
can be precongured based on the variety of modules available down to 35
psig (2.5 bar.g)
.
