Pac 8500 Dual Gas Monitor for Hydrogen-Compensated Carbon Monoxide Measurement (CO/ H2-CP) US
Key Features and Benefits of the Pac 8500 Dual Gas Monitor for Hydrogen-Compensated Carbon Monoxide Measurement (CO/ H₂-CP)
The Dräger Pac 8500 CO H₂-CP is a robust dual gas monitor for hydrogen-compensated carbon monoxide measurement. In this configuration, it selectively measures carbon monoxide up to a hydrogen concentration of 1000 ppm and helps avoid false alarms caused by hydrogen. With a hydrogen-compensated CO sensor with two measuring electrodes, a standard measuring range of 0–2000 ppm, A1/A2 alarm thresholds of 20/40 ppm, a 360° alarm with acoustic and visual signals, and recording of concentrations and results with date and time, the Pac 8500 CO H₂-CP is designed for reliable monitoring under demanding conditions.

Technical Data of the Dräger Sensor XXS CO H₂-CP
The technical data below provides an overview of the key performance characteristics of the included Dräger sensor.
Relevant Cross Sensitivities of the Dräger Sensor XXS CO H₂-CP
The values given in the table are guidelines and apply to new sensors. The specified values may vary by ±30%. The sensor may also be sensitive to other gases (data on request from Dräger). Gas mixtures can be displayed as a sum. Gases with negative sensitivity can cancel out a positive display. It should be checked whether gas mixtures are present.

Application Areas for Portable Gas Detection
Portable gas detection instruments are subject to very diverse requirements. Different application areas require solutions tailored to the measurement task, which also take into account the respective ambient conditions.
It is generally possible to distinguish between the following application areas:
Personal monitoring
These devices are designed to warn the wearer about gas risks in the immediate vicinity. For this reason, they are usually worn on work clothing. The basic requirements that these units therefore have to fulfill are wearing comfort, durability, and reliability. Continuously measuring single-gas and multi-gas instruments are suitable for this kind of work.
Area monitoring
In contrast to the personal gas detector area monitors will be placed at central or critical locations to monitor workspaces optimally and independently from persons. For this, the basic requirements are robustness, stability and excellent alarm awareness (optical and acoustic) as well as a longest possible battery runtime. Increased security level can be achieved by connecting the area monitors to wireless alarm chains and by transferring the measurement values from instrument to instrument as well as to mobile terminals.
Confined space entry
Maintenance and repair work often require people to climb into confined spaces. These areas of work can be especially dangerous because of the lack of space, the lack of ventilation, and the presense or development of hazardous substances. A clearance measurement is required before entry. Multi-gas instruments are used together with corresponding pumps and accessories such as hoses and probes. After a successful measurement where no hazards have been found, the same instruments can be used for continuous personal monitoring while working in the confined space.
Leak detection
Leakages can occur wherever gases or liquids are stored or transported. It is important to identify leakages quickly so that the appropriate measures can be taken to avert harm to people, the environment, and the facility. Detection devices combined with corresponding pumps must be able to respond quickly so as to detect small changes in concentration. High levels of reliability are another minimum requirement for these measuring instruments.
Calibration and Bump Testing Functionality tests
Perform the mandatory function tests before each use with the Dräger test and calibration stations and the associated test gases.
If you want an individual alarm threshold configuration, please specify the alarm thresholds in the comment field at the end of the ordering process.
You can also rent bump test equipment for temporary assignments, projects or additional testing tasks. Click here to see our range of products.
