Important hints

To exclude any risk to persons, it is necessary to connect the sample

gas outlet (TOXIC GAS) of the instrument with the flue gas hose to

the flue gas duct.

Please confirm after successful connection the security message at

the instrument with <OK>.

Please connect flue gas hose to flue

gas duct before starting!

Please confirm (OK) before

starting, that the sample gas outlet

(TOXIC GAS) has been connected

through the flue gas hose to the

Before starting connect the condensate hose

(possibly collect condensate in a vessel)!

To ensure sufficient airflow, a minimum distance

of 0.5 m must be kept to walls or objects!

Adjustments at burners and boilers

should be

made only by specialists, who are familiar

with this installations!

3. 2-stage Peltier cooler

Flue gas with a temperature above the dew point is sucked spiral via

a long gas path thru a surface coated metal body with good thermal

conductivity. The gas radiates its heat to this metal body

A Peltier

element (semiconductor cooling element) flown by a continuous

current is thermally connected with this body and with a second

metal body with cooling ribs and ventilation slots. The current thru

the Peltier element creates a heat transfer from hot to cold, drains

the heat of the metal body flown by gas and transfers it to the outer

cooling body. This heat is transferred thru ventilation to the

surrounding air.

The condensation issued by the heat loss of the gas drops in a

receptacle and is pumped out by a permanent working hose pump.

The sucking capacity of the gas conveying pump avoids a sufficient

dwell time of the gas with the condensate, so that wash out reactions

(NO

O > H

) do not take place. At the cooler outlet the gas

has a temperature of ca. 5 °C with a relative saturation of nearly 100

% relative humidity (corresponds to a water steam content < 7 g/ m

4. Heated sampling system

By using a heated sampling system (option) is possible to measure

water-soluble substances (NO

and SO

) without washout. A built-in

hot gas filter protects the instrument especially for long-term

measurements from fouling. The maximum exhaust gas temperature

when using the heated sampling system is 500 ° C.

Please note:

- Do not bend the tube

- Heated tube has to be cooled out after the

measurement

- Heated tube may not be folded too tight

(use the whole under case)

- Do not put the heated tube in water

- Clean or replace PTFE filter regularly
