Extech VFM200: VOC/Formaldehyde Meter

• Checks for Carbon Dioxide (CO2) concentrations
• Calculates statistical weighted averages of TWA (8 hour time weighted average) and STEL (15 minute short term exposure limit)
• Maintenance free NDIR (non-dispersive infrared) CO2 sensor

 

• A bright flashing LED and loud pulsating beeper indicate local continuity
• Remote continuity with the use of the remote probe
• Flashing remote probe - two lead, bi-color (red/green) LED probe allows a single user to identify up to three wires or cables at a time
• Lightweight and pocketsized, clips on and hangs from the cable(s) under test without falling off
• Great for Electricians and Helpers, Cable TV and Audio System Installers, Alarm Technicians, Plumbers, HVAC Installers etc.
