The testo315-4 is a convenient, precise and robust
measuring instrument for recording ambient CO values.
It identifies even the slightest concentrations of the
highly toxic gas. This allows you to safely judge whether,
e.g.ambient air-dependent heating systems can be
operated without danger.
• TÜV-tested according to EN 50543
• Electrochemical CO sensor for reliable and highly precise
measurement results
• Optical and audible alarm when limit values are exceeded
(freely adjustable limit values)
• Printout of measurement data possible directly on site
