The Additel 273Ex (Intrinsically Safe) is a portable pressure calibrator that redefines field testing in explosive environments. Featuring a vibrant color touchscreen and a smartphone-inspired interface, it integrates quick test tasks and optional HART communication to significantly improve calibration efficiency.

Equipped with a built-in atmospheric pressure sensor, the ADT273Ex seamlessly switches between absolute pressure and gauge pressure measurements. It offers three pressure module ports: one interchangeable internal module at the base and two digital ports on the side. This modularity allows users to customize the device for any pressure calibration environment.

Technical Capabilities:

• High Accuracy: Available with 0.02% or 0.05% FS precision.
• Modular Flexibility: Features field-interchangeable pressure modules and dual digital input channels.
• Modern Interface: High-resolution color touchscreen with an intuitive menu system for a streamlined workflow.
• Onboard Intelligence: Built-in barometer and pre-configured test tasks.
• Communication: Fully equipped with Bluetooth and USB connectivity.
• Certified Quality: Supplied with an ISO 17025 accredited calibration certificate and full measurement data.

Safety and Durability: The ADT273Ex meets the most stringent ATEX and IECEx safety standards (Ex ia IIC T4 Ga). It is designed for hazardous environments such as oil and gas platforms, refineries, chemical plants, pharmaceutical facilities, and power generation sites. The display utilizes a transflective color LCD, ensuring perfect visibility even in direct sunlight.

Optional HART Communication: When equipped with the HART option, the ADT273Ex becomes a comprehensive tool for calibrating pressure transmitters. Users can accurately measure pressure using field-swappable sensors, read mA or mV signals from transducers, and provide loop power to the device under test during calibration.

Summary: The Additel 273Ex is a robust, intrinsically safe handheld calibrator that combines a modern touchscreen interface with professional-grade durability. It is the ideal solution for technicians who require absolute accuracy and reliability in the most demanding industrial environments.
