Testo 340 - Multigas Combustion Engine Tuning Analyzer

The Testo 340 by Testo is a portable, handheld flue gas analyzer designed for combustion tuning and maintenance of engines, boilers, furnaces, and process heating equipment. It measures up to four gases simultaneously — O₂ (0–25% vol.), CO (0–10,000 ppm), NO (0–3,000 ppm), and NO₂ (0–5,000 ppm) — with automatic combustion efficiency and excess air calculations displayed in real time. On-board data storage and an integrated printer enable immediate on-site documentation, making it well-suited for mechanical engineers and facility maintenance teams performing routine combustion tuning and preventative maintenance on commercial heating equipment.
