The SYCON SiO2 is a photometric analyzer for monitoring silica (SiO2) in the ppm range (0.3 to 10 mg/l).

The special features are:

• Compact design with easily accessible components

• Tool-free maintenance of the measuring cell

• Simple and intuitive operation via 8 buttons and large display

• Durable and precise analysis technology

The following functions are reliably displayed by the SYCON Silicate analyzer:

• Automatic zero point adjustment before each measurement

• An individually adjustable limit value for alarm function via relay

• Interfaces for measured value output

• Measured values and log on SD card

• Modbus RTU

• Analog output 4 – 20 mA for measured value or detailed status messages

• Four relay outputs for individual alarm and warning messages and for controlling other components (e.g. sample pump for unpressurized sample water)

• Two programmable digital inputs

The SYCON 2802 is a titration device for measuring water hardness or Alkalinity (Carbonate hardness). The device has four relays, making a large number of connection variants possible. The two input contacts make it possible, the RS485 interface with Modbus RTU protocol and a 4-20mA interface cover all needs of a modern online analyser.

The main features are:

• Monitoring of a freely programmable limit value

• Measurement of residual hardness, total hardness or Alkalinity (carbonate hardness - acid capacity)

• Graphic display, menu navigation in many languages

• Simple commissioning using the installation wizard

• Documentation of all measurement results on an SD card

• Low maintenance

• Self-calibrating before each measurement

The included connections are:

• Four potential-free outputs

• A 4 -20 mA interface for measured value output or status message

• Two input contacts

• Modbus RTU

The SYCON Fe is an analyzer for measuring free iron in a water sample. In addition to the usual relays and input contacts, the online analyzer has a 20 mA current and RS485 interface with Modbus RTU protocol.

The main features are:

• Monitoring of a freely programmable limit value

• Measurement of dissolved iron Fe (II and III)

• Graphic display, menu navigation in many languages

• Simple commissioning using the installation wizard

• Documentation of all measurement results on an SD card

• Low maintenance

• Self-calibrating before each measurementConnections:

The included connections are:

• Four potential-free outputs

• A 4 -20 mA interface for measured value output or status message

• Two input contacts

CALDUR comprises test kits for the manual determination of water constituents. In addition to many standard rapid tests for checking residual hardness, total hardness, chlorine content and iron concentration, the CALDUR range also includes many test kits that are required for niche applications. All products in the CALDUR series are characterized in particular by their ease of use and very precise measurement point determination.

The test sets of the CALDUR scientific series are characterized by particularly easy handling and extremely high accuracy, which cannot be achieved with conventional manual test kits. This is achieved by dosing via a syringe, on the scale of which the measured value can be read directly - instead of counting drops.

The TitraSense is your smart choice for the exact online determination of water hardness in an industrial environment. It combines the proven precision of high-end titration devices with an outstanding price-performance ratio. Ideal for all who do not want to compromise on measurement accuracy but want to keep an eye on costs and for whom it is important that development and production come from a single source.
