Gas detector POLYTRON 7000 - Excellent

Dräger Polytron® 7000 - Gas Detection Made Easy

The Polytron® 7000 stands out as a robust solution for detecting toxic and oxygen gases across a myriad of applications. This gas detector combines user-friendly design with cutting-edge technology, offering both compliance with industry standards and the flexibility required for customized applications.

The Polytron 7000 is engineered to satisfy a broad spectrum of toxic and oxygen gas measurement needs on a single platform. Whether used in chemical plants, oil and gas facilities, or any environment where gas detection is crucial, this device can meet the stringent requirements of regulatory compliance and high-specification tailored solutions.

One of the most impressive features of the Polytron 7000 is its large graphic display measuring 34 x 62 mm (1.3" x 2.4"). With a resolution of 64 x 128 pixels, the display presents critical information clearly, utilizing a combination of icons and real text to guide users through calibration and configuration processes. The intuitive three-button operation simplifies navigation, ensuring that even personnel with minimal training can operate the device effectively.

The Polytron 7000 is designed with a modular architecture that allows for easy integration of various accessories, enhancing its functionality. For instance, the remote sensor adaptor permits the sensor to be positioned up to 30 meters away from the main unit, enabling safe monitoring in hard-to-reach or hazardous areas. This feature allows users to both read and operate the transmitter from a secure location.

Additionally, a pump module can be added to draw gas samples from challenging locations, further increasing the detector's versatility. Each accessory, including a relay module with two gas alarm relays and one fault alarm relay, can be retrofitted to existing systems, minimizing downtime and installation costs.

What truly sets the Polytron 7000 apart is its intelligent sensor technology. Capable of detecting over 100 different gases, DrägerSensors are designed for continuous operation, ensuring long life and reliability. Each sensor features built-in data memory containing essential calibration and gas information, which, combined with onboard temperature and pressure compensation, offers unparalleled measurement accuracy.

Moreover, the device supports pre-calibrated sensors, reducing operator intervention and making maintenance a breeze. The Polytron 7000 is engineered to operate with minimal downtime, establishing it as a virtually maintenance-free gas detection solution.

With a built-in data saving feature, users can easily track measured values, alarms, and warnings. The data can be downloaded via infrared interface to a PDA or PC, allowing for detailed analysis using Dräger GasVision software. The transmitter also provides a convenient 15-minute concentration history directly on the display, ensuring operators have immediate access to critical data.

Safety is a core consideration for the Polytron 7000, which is compliant with various international standards, including ATEX and IECEx certifications. The device operates reliably across a wide temperature range of -40 °C to +65 °C (-40 °F to +150 °F) and is housed in a robust enclosure rated IP 66/67. This ensures that the unit is protected against dust and water ingress, making it suitable for harsh industrial environments.
