1. Introduction
1.1 General Introduction
ADT685 /ADT685EX Advanced Digital Pressure Gauge is the latest generation digital pressure gauges introduced by
Additel Corporation. It is mainly used to calibrate precision pressure gauges, general pressure gauges,
sphygmomanometers or other pressure instruments and it can also be widely used for precision pressure measurement.
The power consumption of ADT685/ADT685EX is very low, which is suitable for long-term continuous work (Up to
20,000 hours under ultra-low power consumption mode). TheADT685/ADT685EX also has excellent electromagnetic
compatibility characteristics, it has obtained the CE certification of the most authoritative organization and can be used in
various complex electromagnetic environments.
