    NOTE: The H25-IR PRO is supplied with a 6 foot grounded AC power cord. Make sure that a compatible AC power receptacle (socket) is available nearby. The H25-IR PRO uses a universal AC power supply that accepts inputs of 100 to 240 VAC, 50/60 Hz. Power consumption is approximately 16 Watts (maximum).

  • Page 27: Internal Components

    For information on replacing the NDIR sensor yourself, refer to Chapter 6: Maintenance (page 88) for more information. Alternatively, you can send your H25-IR PRO to the factory or service center to have the NDIR sensor replaced.

  • Page 28: Chapter 3: Menu System Overview

    The H25-IR PRO is used to locate and quantify gas leaks. Interfaces provide external information, configuration, operation, evaluation results, and even diagnostic information, among other things. Interfaces (i.e., the “borders” between the outside world and the H25-IR PRO) are those key boundaries where the information is exchanged. The main interfaces of the H25-IR PRO are: •...

  • Page 30: Menu Navigation

    3.2.1. Overview Navigating the H25-IR PRO menus is intuitive. Furthermore, it is likely that operators will spend only a proportionally small amount of time configuring the unit versus a greater amount of time at the search and measure screens (locating leaks and quantifying them once they are found).
