Simple to use with high accuracy measurements, the Testo 310 is an excellent solution for all basic measurements on heating systems.

Suitable for both new and existing heating systems, the Testo 310 includes four simple measurement menus for quickly and easily accessing flue gas, ambient CO, draught and differential pressure measurements functions. Two results can be shown simultaneously on the analyser's LCD screen; the top line shows ratio, oxygen, flue temperature, draught, ambient CO, pressure or undiluted CO, while the second line shows carbon monoxide, excess air, net/gross efficiency, ambient temperature, oxygen or carbon dioxide levels.

The Testo 310 has three sensors - an oxygen and CO sensor are built directly into the analyser, while a temperature sensor is integrated into the include flue gas probe. Using these sensors, the 310 measures the oxygen and carbon monoxide content as well as flue gas/ambient temperature, then calculates CO2, efficiency and more using these values.

Want to see the Testo 310 in action? Take a look at this video for more info (please note that the printer shown is NOT included with this kit, but is available as an optional extra).

The Testo 310 is made tough, designed for use within rough and dirty surroundings. It's powered by fully rechargeable lithium batteries (which can be charged via USB connection) with battery life of up to ten hours, has an integrated condensate trap which can be emptied quickly and easily and will automatically zero the gas sensor when first started to ensure accuracy.

Need to keep your hands free when measuring? No problem with the Testo 310 analyser - this unit includes a fully magnetic back, allowing it to be attached directly to a boiler or other metal surface. The optional wireless printer is also magnetic, and can be mounted directly above the analyser for quick, infrared printing in the field (printer sold separately).
