1、 Product Introduction:
The Delger Pac5500 is a new type of single gas detection alarm used for personal protection. This instrument can continuously detect the concentration of carbon monoxide, hydrogen sulfide, or oxygen in the ambient air and sound an alarm in a timely manner. Accurate measurement, compact appearance, sturdy and durable, easy operation, and no lifespan limit.

2、 Performance characteristics:
1. Compact yet sturdy and durable in appearance
The Delger Pac 5500 is highly suitable for personal protection for industrial users and other applications, both in terms of size and weight. The instrument is easy to operate and can be used with one hand even when wearing gloves. It is specifically designed for personnel working in harsh environments. There is a layer of rubber on the outside of the instrument to make it more sturdy and durable, with a protection level of IP66/67, and it can be used normally even in the presence of water. *The position of the sensor in the first instrument is specially designed to allow gas to enter from both the top and front of the instrument at the same time. Placing the instrument in a pocket or accidentally covering the air inlet does not hinder continuous gas detection.
2. No lifespan limit
Designed for long-term operation, the Delger Pac 5500 has no lifespan limit. Batteries and sensors can be easily replaced on-site without the need for any additional equipment. In addition, if the water dust filtration membrane at the top of the instrument is contaminated with dirt and mud, it can also be replaced.
3. Micro sensor technology
Equipped with the latest micro Delger X X S sensor technology, the Delger Pac 5500 is tailor-made for personal portable testing. The innovative sensor combines excellent performance and fast response time, with an expected lifespan of up to 5 to 8 years.
4. High definition display
The large LCD screen is clear and bright, displaying both gas concentration and measurement units. As an option, the instrument can also be set to display only gas types on the screen. The gas concentration is only displayed on the screen when the alarm level is reached. To avoid language barriers, the concentration display does not use any text. The background light on the display screen is turned on for easy reading in dark environments. In addition, yellow (hydrogen sulfide) and blue (oxygen) labels ensure rapid identification of instruments from a distance.
5. Warning and alarm
The Delger Pac 5500 not only has sound vibration alarm function, but also provides 360 ° visual light alarm at the top and bottom of the instrument. The alarm limit value can be set by the user for gas alarms, including pre alarm and main alarm. To ensure user safety, the instrument battery level alarm includes pre alarm and main alarm. So once there is any circuit, battery or sensor problem with the instrument, users can immediately receive clear default alarms and prompts. The "life signal" function option can also be activated according to the user's request or *.
6. Functional testing and calibration
The vast majority of regulations require users to conduct routine tests on instruments using known concentrations of gases. Functional testing can check whether the instrument is working properly. The Delger Pac 5500 is equipped with adjustable functional testing and calibration intervals to meet different application configurations, and a warning will be automatically displayed on the screen when the required date for functional testing and calibration is reached. If the warning is ignored, the instrument can automatically display an error message of "malfunction". Users can also choose to set this error message prompt for calibration interval expiration. The Delger Pac5500 can be used in conjunction with the Delger functional tester, and testing can be quickly and easily completed in just 8 to 15 seconds each time. This economical device does not require a power supply and can be used to check instruments and sensors at any location. Each successful test is automatically recorded in the data storage, while any failed test will prompt the instrument to "malfunction". You can also choose a portable printer and print text results. After turning on, fresh air calibration can be easily performed. Calibration can be performed in the workshop by connecting the instrument and computer, and automatic testing and calibration of the system can be selected. The inspection cycle for Delger Pac5500 * is 2 years.
7. Data storage
The Delger Pac 5500 can record 60 events including date and time, and can be paired with an infrared interface and data cable to connect to a computer. Typical events such as on/off, gas and battery alarms, mode errors, configuration changes, fresh air calibration, and functional testing can all be downloaded, printed, and stored.
