Page 5: Introduction
INTRODUCTION The KK650 measures hydrogen in the ranges 0 to 5% or 0 to 10% (depending on the model), and also chlorine in the range 0 to 100%, when these gases are mixed with air. It is designed specifically for the chlor-alkali industry. Chlorine is usually manufactured by the electrolysis of brine (sodium chloride) or potassium chloride. -

Page 9: Installation
INSTALLATION WARNING The weight of this equipment is in excess of 18kg, and the use of mechanical handling equipment or assistance from additional personnel is recommended when handling and mounting. Unpacking and visual checking Take all standard precautions when opening packages. In particular avoid the use of long bladed cutters. - Page 10 NOTE Care must be taken to ensure that the tubing etc, carrying the sample from the take-off point to the katharometer entry is completely obscured from any light, otherwise the analyser will report a lower hydrogen concentration for the sampled process gas. This fact would of course be true for any other thermal conductivity analyser performing this measurement.

Figure 6 The cables from the katharometer/reactor unit are identified by number tags that correspond to the terminal numbers on the label. The two heavier wires (labelled 9 and 10) in the black cable from the katharometer should be connected to the DIN-rail mounted terminals between the two carriers.

OPERATION First checks It is advisable to make a thorough check of all connections – particularly the pipe work – before applying any sample. WARNING Chlorine is a highly toxic and corrosive gas and it is of utmost importance that there are no leaks. - Page 15 View mode configuration screens View Mode Configuration Screens Hydrogen in Chlorine Analyser KK650 MTL Hydrogen in Chlorine Analyser Hydrogen in Chlorine Analyser Press the VIEW key See next section for to access screen 1 View Edit information on the use...

Page 17: Calibration
CALIBRATION General notes Provided the katharometer does not become contaminated, instruments can be expected to hold their calibration repeatability to better than 0.02% hydrogen for a lengthy period. Chlorine accuracy varies according to air and hydrogen concentrations. In the 90 to 100% range it is approximately 0.5% going out to about 1.5% at lower concentrations with high hydrogen. -

Page 20: Service And Maintenance
SERVICE AND MAINTENANCE General In keeping with all of our products, the KK650 is a highly reliable analyser. If a fault is apparent on a new installation, the wiring, etc., should be checked thoroughly. Similarly, if the instrument appears not to power up, ensure that a proper supply is in place and that the two fuses are intact. - Page 21 NOTE The codes are additive. E.g. if a code of 5 was displayed it would mean that Vo1 AD counts were less than (-)4093 and Vo2 AD counts were less than (-)4093. Vt is the internal voltage signal that indicates the katharometer’s temperature Vo1 is the internal voltage signal that is a function of the difference between the two katharometer sense signals at terminals 1-2 and 3-4 in Figure 6.
