Additel ADT686 Series


ADT686 Series Features


Overview

The Additel ADT686 Advanced Digital Pressure Gauges will redefine the way users 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 users expect from genuine Additel products. The modern menu structure and control interface brings a refreshing experience to pressure calibration work. This completely novel way of interfacing with Additel 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, users can configure ADT686 gauges to precisely fit specific pressure calibration and measurement needs. With an IP67 rating, users will find that these amazing pressure gauges can be used in the field or laboratory to meet the most demanding pressure calibration needs.

A Modern User Experience:
The ADT673 has a 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, users will find these ADT686 calibrators simple yet powerful to use. The easy-to-read display is not only fun to use, but it is built rugged, so that it can handle the demands of a busy technician in the field 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 50 Pa. With this unique feature, the ADT685 can be a solution for three common applications: gauge pressure measurement, absolute pressure measurement, and barometric or atmosphere pressure measurement.

Additel ADT686 gauges are available in an optional intrinsically safe (Ex) version and cover gauge, absolute, differential and compound pressure ranges. Each gauge contains a built-in barometer sensor which allows for the pressure reading to display in gauge pressure or absolute pressure with a simple menu selection. These new gauges can also be configured with an optional data logging capability which allows users to store up to 10,000,000 readings. Each gauge comes with an ISO-17025 accredited certificate of calibration. It is compatible with Additel’s Link mobile app and 9502 Additel/Log II software, which enables the ability to monitor and display the real-time pressure measurements in a table or graphically.
