DNR-18 Leak Detector with Digital Noise Reduction

The *DNR-18 Leak Detector* processes leak sound digitally to reduce traffic and other noises that disturb detection work.
Using the DNR-18 and its advanced digital noise reduction system, operators can pinpoint difficult to find leaks — even in noisy daytime environments.
A large backlit LCD provides simultaneous noise level, filter-setting, and recorded level display. Noise level recording and USB data output enable detailed analysis on a PC.

Features

Advanced noise reduction and filtering
Eliminate traffic noise, impact sounds, footsteps and more with digital noise reduction and detailed high- and low-pass filtering. Remove A/C hum noise from power lines and transformers using the 50/60Hz notch filter.

Large LCD display for detailed data analysis
The large LCD provides simultaneous noise level, filter-setting, and recorded level display. View a graph of the noise level value to analyze changes over time.

Leak noise level recording and USB output
Record noise data for up to 250 locations in the unit memory for onsite reference, and download the noise level data to a PC by USB cable.

Built for demanding professional environments
A dustproof and water resistant enclosure allows operators to keep working in light rain or splash-prone environments. The LCD display is backlit for night use.
