About the Testo 320B Flue Gas Analyser

Designed specifically for the UK market, the Testo 320B is a professional, reliable and accurate flue gas analyser that makes it easier than ever to check a boiler's operation.

Equipped with a high-quality, full-colour screen with graphical display, the 320B allows you to test quicker as it displays multiple measurements at the same time on the screen. It's then possible to save up to 20 readings on the analyser's memory, then transfer it to PC for further analysis (or send it to the included printer for quick documentation).

The Testo 320B is compatible with all common fuel types, including natural gas, butane, propane, light oil, kerosene, heavy oil, wood pellets, coal, anthracite and coke. It can test absolutely every aspect of a boiler's operation, including timed CO build-up, let by and tightness, differential temperature, draught, pressure, CO, O2 and CO2, flue/ambient temperature, excess air and gross/net efficiency.

The Testo 320B is supplied as standard with a unique temperature probe with built-in thermocouple. This pistol-style probe plugs easily into the meter for quick and efficient testing of flue temperature. A built-in condensate trap on the 320B also ensures that excess moisture is trapped before it can cause damage to your meter's innards; this can easily be emptied as needed simply by opening the trap and pouring out the excess water.

It doesn't stop there either - the 320B also includes a lithium ion rechargeable battery, an automatic CO sensor protector which will shut off the pump in the event of danger and even comes with a 3 year instrument and sensor warranty for peace of mind.
