SECTION 1: INTRODUCTION

1.1. Purpose

The previous generation of the H25-IR Pro leak detector had an internal filter that required disassembly for replacement.
This was changed in the newer model of the H25-IR Pro to an external filter found at the rear of the instrument. The
purpose of this document is to explain the procedure for upgrading an older-style H25-IR Pro leak detector to include the
newer external filter.
