RLE Technologies

RLE Technologies has merged with Cellwatch to become Parameter; the same excellent team that has been driving innovation in leak detection and environment monitoring for over 40 years, now with a new face.

We’ve moved on from the classic RLE Tech website, but you can still view and interact with it through the link below. Just keep in mind that this website has stopped receiving updates and regular maintenance.

We appreciate all our customers and partners who met us as RLE Technologies, and we don’t want this change to impact any existing workflows or routines. That’s why all the email addresses, order processes, and websites you are familiar with will stay intact and functional while we move forward as Parameter.
