CLD 800 series configuration tables

All analysers in this series start with the model I.D. CLD 8 the numbers and letters that follow indicate which measurement ranges and options are incorporated into the unit.

Using the tables below replace the highlighted x in the top row with the highlighted number or letter that represents the modules that you require.

Our experts will be happy to help if you require assistance making your choice.

Step one - Define the maximum measuring range. The number in the highlighted column indicates the maximum measuring range required.
Example:
CLD 82 would have a maximum measuring range of up to 5000 ppm

Note:
Options 6 & 8 are only available as single reaction chamber analysers.

CLD 8	x	x
	2	= 5000 ppm
	4	= 500 ppm
	6	= 50 ppm
	8	= 5 ppm

Step two - If a second reaction chamber is required select the maximum measuring range. If not required leave blank.

Note:
In general, the second measurement range should be identical to the first. The only case where you can select a different range is when you operate the CLD in dual mode with two sample inlets. The only choice in this case is the combination CLD 824 d

Example:
CLD 844 would have two reaction chambers with a maximum measuring range of 500 ppm.

CLD 8x	x
		= not required
	2	= 5000 ppm
	4	= 500 ppm

Step three - Depending on the type and concentration of the gas components in your sample gas you may select an appropriate converter. The respective letter goes after the model numbers.

Explanation:
For general purposes and rough conditions select the steel converter S. If your gas sample is a simple mixture:
For higher concentrations select the metal converter M For lower concentrations select the Molybdenum converter Y The catalyst C is best suited for the total conversion of amines (including ammonia) and nitrogen oxides.

CLD xx	X
	S	= Steel
	M	= Metal
	Y	= Molybdenum
	C	= Catalyst

Step four - Options By completing the tables above you have defined the basic configuration of your personal analyser.

If you require assistance with your choice of further options our experts will be happy to help.

To help you make the right choices we need answers referring to the physical conditions of your measurement task, such as

gas composition (in particular humidity and CO₂ concentrations).
temperature of the sample gas
intended sample preparation (e.g. use of a gas cooler)
sample inlet pressure (variable or stabilised)

CLDxxX	x
	r	=	Pressure regulation (600-1200 mbar)
	h	=	Heated inlet (hot tubing)
	d	=	Second sample gas inlet (dual)
	l	=	Calibration unit (excluding option r)
	v1	=	Calibration valve for span gas
	v2	=	Calibration valves (zero & span gas)
	f	=	Filter for sample gas inlet
	p	=	Pre-chamber (only CLD86/88)
