compact threshold monitoring of total hardness, ideal as a hardness guard downstream of water softeners<\/li>\n<li><strong>SYCON 2602<\/strong> &ndash; colorimetric threshold monitoring with graphic display, relay outputs and SD card<\/li>\n<li><strong>SYCON 2702<\/strong> &ndash; titration analyzer with exact measured value, 4-20&thinsp;mA output and Modbus interface<\/li>\n<li><strong>SYCON 2802<\/strong> &ndash; premium titration analyzer with two thresholds, four relays and full interface range<\/li>\n<\/ul>\n<p>A detailed comparison of all models is available on the <a href=\"https:\/\/rls-wacon.de\/en\/sycon-comparison\/\" target=\"_blank\">SYCON comparison page<\/a>.<\/p>\n<h3>Which indicator is required?<\/h3>\n<p>The appropriate indicator depends on the <strong>parameter<\/strong> to be monitored (e.g. total hardness, carbonate hardness) and the <strong>measuring range<\/strong>. Various H25 indicators are available for hardness measurement, each covering a specific range. The expected measured value should ideally be in the middle of the indicator&#8217;s measuring range.<\/p>\n<p>An overview of all available indicators with measuring ranges and compatible devices can be found on the <a href=\"https:\/\/rls-wacon.de\/en\/product-category\/water\/online-analytics\/reagents\/\" target=\"_blank\">indicator comparison page<\/a>.<\/p>\n<h3>How does the measurement work?<\/h3>\n<p>All SYCON devices operate fully automatically. The sample water is fed into the measuring chamber and an indicator is dosed automatically. An optical sensor then evaluates the color reaction.<\/p>\n<ul>\n<li><strong>SYCON 2602 &amp; LIMES<\/strong> &ndash; operate using the colorimetric threshold method: the device evaluates the color intensity after the indicator is added and detects whether the set threshold is exceeded or not.<\/li>\n<li><strong>SYCON 2702 &amp; 2802<\/strong> &ndash; operate using the colorimetric titration method: the indicator is dosed incrementally. The device calculates the exact concentration of the water constituent from the color change during dosing.<\/li>\n<\/ul>\n<h3>Which parameters can be monitored besides water hardness?<\/h3>\n<p>In addition to total hardness<br \/>\n   and carbonate hardness, the SYCON series covers further important parameters in water<br \/>\n  analytics:<\/p>\n<ul>\n<li><strong>Iron (Fe)<\/strong> &ndash; with the SYCON Fe<br \/><em>Elevated iron levels cause<br \/>\n  discoloration in drinking water and deposits in pipelines &ndash; particularly relevant when treating well<br \/>\n  water<\/em><\/li>\n<li><strong>Silicate (SiO2)<\/strong> &ndash; with the SYCON SiO2<br \/><em>Even low silicate<br \/>\n  concentrations can lead to deposits on turbine blades &ndash; continuous monitoring protects costly power plant<br \/>\n  components<\/em><\/li>\n<li><strong>p-value \/ alkalinity<\/strong> &ndash; with the SYCON P<br \/><em>The p-value is a key<br \/>\n  parameter for corrosion protection in boiler water and cooling water circuits<\/em><\/li>\n<\/ul>\n<p>Each device is<br \/>\n  specialized for its parameter and operates fully automatically using the same proven measurement principle.<\/p>\n<h3>What are the typical application areas for the analyzers?<\/h3>\n<p>SYCON and LIMES devices are<br \/>\n  used in many areas of water treatment and monitoring:<\/p>\n<table>\n<tr>\n<th>Device<\/th>\n<th>Typical<br \/>\n  application areas<\/th>\n<\/tr>\n<tr>\n<td><strong>LIMES<\/strong><\/td>\n<td><strong>Water softening systems, soft water<br \/>\n  monitoring, building services<\/strong><br \/><em>Prevent limescale deposits in pipelines and heat exchangers early on<br \/>\n  &ndash; an exhausted softening system often goes unnoticed without monitoring<\/em><\/td>\n<\/tr>\n<tr>\n<td><strong>SYCON<br \/>\n  2602<\/strong><\/td>\n<td><strong>Water softening systems, industrial processes, drinking water<br \/>\n  treatment<\/strong><br \/><em>Reliable threshold monitoring with automatic regeneration triggering &ndash; protects<br \/>\n  systems and saves regeneration chemicals through demand-based control<\/em><\/td>\n<\/tr>\n<tr>\n<td><strong>SYCON 2702 \/<br \/>\n  2802<\/strong><\/td>\n<td><strong>Waterworks, industrial process water treatment, boiler feed water, district heating<br \/>\n  networks<\/strong><br \/><em>Precise measured values enable accurate control and documentation of water quality &ndash;<br \/>\n  essential wherever limit values must be verifiably maintained<\/em><\/td>\n<\/tr>\n<tr>\n<td><strong>SYCON<br \/>\n  BoB<\/strong><\/td>\n<td><strong>Steam boiler systems, monitoring of boiler feed water and<br \/>\n  condensate<\/strong><br \/><em>T\u00dcV-certified according to W\u00dcV 100 &ndash; meets the requirement for 72-hour operational<br \/>\n  monitoring of steam boiler systems<\/em><\/td>\n<\/tr>\n<tr>\n<td><strong>SYCON Fe<\/strong><\/td>\n<td><strong>Drinking water<br \/>\n  treatment, well water monitoring, corrosion control<\/strong><br \/><em>Elevated iron levels lead to discoloration and<br \/>\n  deposits &ndash; continuous monitoring detects problems before they become visible to the<br \/>\n  consumer<\/em><\/td>\n<\/tr>\n<tr>\n<td><strong>SYCON SiO2<\/strong><\/td>\n<td><strong>Power plants, mixed bed filter monitoring,<br \/>\n  ultrapure water treatment<\/strong><br \/><em>Even low silicate concentrations can cause turbine deposits &ndash; early<br \/>\n  detection protects costly plant components<\/em><\/td>\n<\/tr>\n<tr>\n<td><strong>SYCON P<\/strong><\/td>\n<td><strong>Boiler water<br \/>\n   monitoring, cooling water circuits, industrial processes<\/strong><br \/><em>The p-value (alkalinity) is crucial for<br \/>\n  corrosion protection &ndash; a value that is too low or too high attacks pipelines and heat<br \/>\n  exchangers<\/em><\/td>\n<\/tr>\n<\/table>\n<h3>What are the requirements for connection?<\/h3>\n<p>The following conditions should be met for trouble-free operation:<\/p>\n<ul>\n<li><strong>Water pressure:<\/strong> min.&thinsp;0.5&thinsp;bar, max.&thinsp;5&thinsp;bar (recommended 1&ndash;2&thinsp;bar)<\/li>\n<li><strong>Water temperature:<\/strong> 5&ndash;40&thinsp;&deg;C &ndash; a sample cooler should be used at higher temperatures<\/li>\n<li><strong>Water quality:<\/strong> clear, free of solids and without gas bubbles<\/li>\n<li><strong>Power supply:<\/strong> depending on device variant 24&thinsp;V&thinsp;AC\/DC or 100&ndash;240&thinsp;V&thinsp;AC &ndash; please check the rating plate<\/li>\n<li><strong>Drain hose:<\/strong> keep as short as possible and lead freely into a funnel or drain<\/li>\n<\/ul>\n<p>Detailed installation instructions can be found in the respective operating manual.<\/p>\n<h3>How often is maintenance required and what is needed?<\/h3>\n<p>All SYCON and LIMES devices operate largely maintenance-free.
