Product Details
Testo 330-2 LL Pro Flue Gas Analysis Kit
Product Introduction
The Testo 330-2 LL Pro Flue Gas Analysis Kit is a TÜV-tested,
high-performance tool designed for precise and reliable flue gas
analysis in heating system installations, maintenance, and service.
Engineered for long-term use, it combines ease of operation with
advanced features, ensuring quick and accurate measurements of key
parameters like CO, O₂, and temperature. With a 4-year warranty and
longlife (LL) sensors that reduce replacement frequency (typically
once every six years), it offers cost savings and durability,
making it an essential instrument for professionals in the heating
and combustion industry.
Features
- Longlife (LL) O₂ and CO sensors, reducing replacement needs
(usually once every six years) to lower maintenance costs.
- Versatile with a wide range of optional sensors (NO, COlow, NOlow,
etc.), allowing customization to meet specific measurement
requirements without needing additional tools.
- Quick and easy sensor replacement via a bayonet lock connector,
simplifying maintenance and minimizing downtime.
- High-resolution 240 x 320 pixel color graphic display, presenting
measurement data clearly with flue gas matrix and line diagram for
intuitive analysis.
- Comprehensive measurement capabilities: flue gas parameters (CO,
O₂, temperature), draft, pressure (burner pressure, gas flow
pressure), CO ambient air (with optional sensor), gas leak
detection, and pressure difference.
- Integrated sensor monitoring with traffic light color coding for
at-a-glance status checks, ensuring reliable performance.
- No need to withdraw the sensor from the flue for zeroing,
streamlining workflow compared to basic models.
- Automatic CO thinning (from 8,000 ppm to at least 30,000 ppm),
expanding measurement range for high-concentration scenarios
(exclusive to 330-2 LL).
- Logger function with a maximum memory of 500,000 readings,
supporting long-term data recording and analysis.
- Integrated magnets for easy attachment to metal surfaces, enhancing
convenience during on-site measurements.
- Easy-to-empty condensate collection tank, maintaining hygiene and
functionality.
- Optional Bluetooth interface for connection to a testo BLUETOOTH®
printer, enabling quick report generation.
- TÜV-tested according to 1st BImSchV EN 50379, Parts 1-3, ensuring
compliance with strict industry standards.
