We are at your side
Do you have questions, problems or suggestions regarding our products? Despite all our quality and care, something may occasionally go wrong – please contact our technical support. We will be happy to help you with any concern using our expertise.
Your direct line to the manufacturer
Our devices and reagents are mostly used by water treatment companies and specialist firms that handle installation, maintenance and service for their customers. If a technician ever gets stuck, the way to us is short: you speak directly with the manufacturer in Hildesheim – and get advice, repair and original parts from a single source.

How we support you
Technical support
A direct line to the manufacturer when your technicians get stuck during operation or troubleshooting – by phone, by email or in a web meeting.
Repair & servicing
Professional repair with original parts at our Hildesheim plant – including a function test before the device is returned.
Spare parts & reagents
Original spare and wear parts, reagents and accessories – an exact fit and usually available for many years.
Training via web meeting
For new customers, we can demonstrate operation, maintenance and cleaning live in a web meeting on request – no travel required.
Take-back of old devices
As the manufacturer, we take back end-of-life devices and send them for proper recycling in accordance with the ElektroG.
Application advice
Which method, which reagent, which analyzer for your water? We help you choose and answer measurement questions.
Sending in a device – it’s that easy
Whether repair or disposal of an old device: the procedure is the same – only the label on the package differs.
Notify us in advance
Simply call +49 (0) 5121 28 126 24 or email support@rls-wacon.de – with the serial number and a short description.
Clean & pack
Clean the device and remove reagents from tubes, pumps and measuring chambers. For disposal, also remove the battery (CR2032) and SD card. Use the original packaging if possible.
Label & ship
Label the package with “ZUR REPARATUR” (for repair) or “ZUR ENTSORGUNG” (for disposal) and send it to our address.
For repair
We inspect the device and get back to you – for chargeable repairs with a transparent cost estimate. After your approval, we carry out the repair and return the device.
Within the warranty period, repairs are usually free of charge. Outside the warranty, you will receive a cost estimate in advance – repairs are only carried out after your approval.
We use only original parts and test every device for proper function before returning it.
For disposal
We send your end-of-life analyzer for proper, environmentally sound recycling in accordance with ElektroG / WEEE.
Electrical devices must not be disposed of with municipal waste (crossed-out wheelie bin symbol). The manufacturer obligation applies to commercially used devices placed on the market after 13.08.2005 (EU Directives 2002/96/EC & 2008/12/EG).
Before shipping: Remove reagents from tubes, pumps and measuring chambers. Remove the backup battery (CR2032) and – for data protection reasons – the SD card; dispose of the battery separately.
For warranty claims, you will receive a free return label.
