Thanks to the new instrument functions, the Testo flue gas analyzers of the new testo 330-LL series now offer you even more professional and reliable support. These are the main features: • High-resolution colour display for the graphic representation of your measurement data • Extended measurement menus – such as gas pipe testing – for a comprehensive analysis of your heating system • Logger function for easy long-term recording of the measurement curve
• Graphic processing of measurement data
• Instrument diagnosis function uses easy „traffic light’’ presentation to enable comprehensive instrument diagnosis
• Pressure measurement up to 300 mbar
• User-defined fuels
• TÜV-tested according to 1. BImSchV / EN 50379 Part 2 for O2, °C, hPa and CO with H2-compensation
• Powerful memory management: 500,000 readings
• IrDa/ Bluetooth interface for data transfer to Pocket-PC / laptop / printer
• USB interface for data readout to a PC software
• ZIV (Central Guild Association) driver for all standard industry software packages
