OVERVIEW
Additel's 686 Advanced Digital Pressure Gauges will redene the way you want to measure pressure! With wireless
remote connectivity, microprocessor technology, state of-the-art silicon pressure sensors and optional onboard
storage capacity, these attractive and fully temperature compensated gauges will provide the performance, durability
and reliability you’ve come to expect from genuine Additel products. The all new modern menu structure and control
interface bring a new and refreshing experience to pressure calibration work. This completely new way of interfacing
with our gauges makes the ADT686 a real pleasure to use. The handy Additel Link app gives users the ability to
remotely monitor these gauges from the convenience of a personal device or cell phone. With an abundance of
options to choose from, you can congure these pressure gauges to precisely t your specic pressure calibration
and measurement needs. With an IP67 rating, you will nd that these amazing pressure gauges can be used in the
eld or laboratory to meet the most demanding pressure calibration needs.
A Modern User Experience:
Additel has gone above and beyond to provide our customers with the best possible experience when using these
new and revolutionary gauges. The 3.4 inch color touchscreen display comes with a protective replaceable tempered
glass screen and is a refreshing update to the traditional push button or blister pad interface. With an easy to navigate
menu structure and fast touchscreen response, you will nd these ADT686 gauges simple yet powerful to use. The
easy to read display isn’t just fun to use, but it’s built rugged to handle the demands of a busy technician in the eld
or the laboratory.
Every model measures Gauge or Absolute Pressure:
The Additel 686 Digital Pressure Gauges contain a built-in barometer sensor which allows for the pressure reading
to display in gauge pressure or absolute pressure with a simple menu selection. The built-in barometer is calibrated
and certified to an accuracy of 55 Pa. With this unique feature, the ADT686 can be a solution for three common
applications: gauge pressure measurement, absolute pressure measurement, and barometric or atmosphere pressure
measurement. Having an Additel as your gauge will always give you the ability to do more with one instrument!
