Gas detector DEX-P9E5/N oxygen, measurement range 25 %v/v, electrochemical sensor 5-year life RoHS, P4-C design, aluminum housing

Gas detectors – reliable protection and precise measurement.

The DEX/P series detectors are devices designed for continuous monitoring of gas or liquid vapor concentrations in enclosed spaces. They find application wherever the detection of explosive, toxic substances or oxygen level control is required. Equipped with an analog current output of 4-20mA, these detectors enable easy integration with various control and alarm systems, such as measuring and threshold control modules MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16 and addressable modules MDD-1, MDD-1/T, MDD-1x/T. Cooperation with other control panels accepting the 4-20mA (current emission) input line standard is also possible after using a power limiter such as MDPL1.

The DEX-P9E5/N detector is designed to measure oxygen concentration in the range of 0 to 25% by volume. It uses an electrochemical sensor with an estimated lifespan of 5 years, compliant with the RoHS standard. The device has an aluminum housing and is made to P4-C standard. The explosion-proof design allows for safe use in areas at risk of explosion of gases or flammable vapors (IIA, IIB, IIC) of various temperature classes (T1 to T6).

Application and functionality

GAZEX detectors meet the requirements of the ATEX Directive 2014/34/UE and are certified for operation in a potentially explosive atmosphere. This makes them a reliable solution for the chemical, petrochemical, mining and other industries exposed to the risk of dangerous gas concentrations. Built-in thermal and linear compensation algorithms ensure accurate measurements even in changing environmental conditions. Replaceable sensor modules minimize operating costs and simplify the calibration process. All detectors are factory calibrated in the GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), which guarantees high accuracy and reliability of measurements.

Key product features:

• Precise oxygen measurement: Measurement range 0-25% v/v ensures accurate monitoring of oxygen levels in the air.
• Long sensor life: Electrochemical sensor with a 5-year lifespan minimizes the need for frequent replacement and calibration.
