Heated sampling probe with glass liner and nozzle. Pitot attached	Heated filter holder.Capable of holding thimble and flat filters. The heated box is maintained at 120 degrees celsius using a temperature controller.


Heated probe in the stack connected to condenser and sampling pump box. A combustion gas analyser is measuring O2,CO2,CO,NO and NO2	Heated filter box fitted with a 30mm x 80mm glass fibre filter.


Pump box fitted with all of the necessary controls to allow isokinetic sampling. Sampling rate can be calculated using either the flowmeter, gas meter or orifice gauge.	Sampling probe in the stack, looking in from the opposite port.


Heated probe fitted with a heated teflon line to prevent the sampled gas from condensing as it travels to the condenser.	Stack testing is very labour intensive. The technician will manually monitor the sampling rate for each run conducted.
