Welcome to EDS Precision SystemsTM. We provide the patented Precision Water Level (PWL) – a tool that often pays for itself on the first use by reducing leveling time 80% or more. A Standard PWL Kit has an accuracy of +/- 0.0003 inches at up to 200 feet (+/- 7.6 µm at up to 61m) in stable conditions. High-End PWL Kits are accurate to +/- 0.0001 inches. PWLs are also inexpensive, portable, do not require line of sight, and are easy to use (no certification required).
For more information on the PWL, please visit the PWL page or contact us. For more on our history and relationship with Equipment Development Services, please our History page. Equipment Development Services and the Rochester, NY based EDS Measurement Systems produce other tools identified on this site and their contact information is also on the contact page.
