Digital Pressure Gauges
Additel 601Ex
The ADT601Ex intrinsically safe digital pressure gauge is designed to improve upon traditional dial pressure gauges
by providing a reliable and accurate digital solution for a minimal investment. The included Bluetooth technology
allows users to connect directly to mobile phones for remote monitoring. This genuine Additel gauge was designed
for the eld to be an economical, but accurate and dependable gauge for use in a variety of environments, including
intrinsically sensitive areas.
Intrinsically Safe
The ADT601Ex has passed the most stringent ATEX, IECEx intrinsic safety certications. Each unit complies with a
certication level of Ex ia IIC T4 Ga. This highly qualied reference recorder can be widely used in potentially explosive
gas environments, such as oil and gas platforms, refineries, chemical and petrochemical plants, pharmaceutical
industry, energy and gas processing industry.
With a durable stainless steel outer shell, welded silicon piezoresistive sensor, and drop test rated to 1 meter, these
gauges are up to the task in the most demanding environments. The dustproof and waterproof rating (IP67), coupled
with the shock and vibration resistance (5g vibration 10g shock) offer even more insurance that these gauges are
durable. If that wasn’t enough, we’ve also designed them to handle up to 3X overpressure to guard against over
pressure damage.
Field operators often have tight schedules and high task loads, and there is no extra time for making mistakes. This
means that the digital pressure gauge must be simple and easy to use. The ADT601Ex series gauges are carefully
designed with button functions which can be operated smoothly and quickly. The display is clear in bright sunlight, and
the backlight can be turned on with one touch for darker ambient conditions. The pressure value can be displayed in
large fonts and the pressure can be read from a few meters away. The pressure change trend bar is simple and clear.
Easy maintenance
The ADT601Ex is designed with membrane buttons, which can simply be wiped clean for quick and simple cleaning.
Coupled with the extra-long battery life of these easy-to-use gauges, you will find that maintenance is minimal and
