    Testo 300 NOx Flue Gas Analyser Kit

    For a limited time only, purchase a Testo 300 NOx Flue Gas Analyser Kit and receive a FREE first year of service worth over £100. Offer ends the 31st of December 2020.

    The Testo 300 NOx Flue Gas Analyser Kit is a sleek, modern instrument set that provides smartphone-style operation in combination with the powerful testing capabilities for which Testo are well known. It contains the advanced Testo 300, a printer, a flue probe and a software package. Notably, the Testo 300 NOx Kit comes with nitrogen oxide measurement.

    Testo 300 Flue Gas Analyser

    The Testo 300 NOx Flue Gas Analyser is capable of measuring oxygen (0 to 21%), efficiency (0 to 120%), carbon monoxide (0 to 4000ppm), carbon dioxide (calculated), draught (-9.99 to +40mbar), pressure (-100mbar to 200mbar), and temperature (-40˚C to 1200˚C).

    The factory-fitted NO sensor on the Testo 300 works together with a preset level for NO2 to produce a value between 0 to 3000ppm with a resolution of 1ppm and accuracy of ±5ppm, ±5% or ±10% depending on the measurement range.

    Nitrogen oxides are a major contributor to poor air quality and are dealt with the ErP directive in force since September 2018. The analyser can even produce a mg/kWh value to see whether boilers comply with the statutory limits contained within the directive. The Testo 300 has a large onboard memory, innovative touchscreen interface and sophisticated analytical functions.

    Testo Flue Probe

    The Testo 300 NOx Kit comes supplied with a standard flue gas probe which allows the user to take measurements directly from a combustion system’s flue. It has a ø6mm x 180mm shaft and includes 10 spare paper filters that prevent dust and water ingress into the analyser.

    Testo IrDA Printer

    The user can print hard copies of results and reports thanks to the Testo Wireless IrDA Printer. An IrDA connection can be used to transfer data wirelessly and the printer will then store measurements so that the user can carry on testing whilst printing is ongoing.

    Testo EasyHeat PC Software

    Testo EasyHeat PC Software can be used to manage data downloaded from the Testo 300 in a logical database with a customer and site tag. It also allows the user to configure flue gas analysers directly from a PC depending on the task at hand.
