Ultrasonic Leak Detector with Located the Leak Location Quickly: The leak detector adopts advanced ultrasonic sensor technology, Use sound waves with frequencies generated near the leak to determine the correct location of the leak, can quickly, accurately and intuitively find out all types of pressure or vacuum system gas..
Air Leak Detector with Multi-scene leak detection: Liquid leakage faults can detect the degree of sealing of enclosed parts such as cabins, car cockpits, refrigerators, and containers. Place the transmitter in the vehicle and close the doors and windows.Trace the detector around outside of the screen, windows and door seals to locate the leak.
Ultrasonic Leak Detector with Excellent Quality：The ultrasonic leak detector has the advantages of small size, light weight, accurate and reliable, convenient operation, practicality, etc. It is a practical portable detection instrument..
Snoop Leak Detector with Two Measurement Methods: For real-time detection of gas pipelines, EM282-R can be used alone to capture the tiny ultrasonic signals generated when gas leaks to detect gas leaks.
And non-real-time detection is that EM282-R capture the ultrasonic signal from EM282-T. Once a leak occurs, ultrasonic waves will leak out through the leak ....

HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal.
This module has stable performance and accurate measurement distance..
Detection distance: 0.78~196 in/ (2cm~500cm).
This module is fully Compatible with GH-311 anti-theft module..
HC-SR04 Ultrasonic Sensor Distance Module for Nano Robot XBee ZigBee by ElecRight.

Located the leak location: Because the sound frequency of the leak port is different from other places, it quickly determine the leak port, suitable for all types of pressure or vacuum system gases..
Check the degree of sealing: Adopt the advanced ultrasonic sensor technology to detect leaks of steam and liquid , detect the sealing degree of closed parts, such as cabins, car cockpits, refrigerators and containers..
Two measurement methods: real-time detection that EM282-R detects leak port by the sound frequency.
And non-real-time detection is that EM282-R capture the frequency signal from EM282-T. If there is gas in the pipe or tank, use real-time detection, or use non-real-time detection.
Adjustable sensitivity, frequency response: 40KHz±2KHz, adapt to various degrees of leakage, easy to detect and improve measurement accuracy..
Ultrasonic testing, fast and accurate, simple to use, green and environmentally friendly. With headphones, indicator lights, beginners can also quickly learn to use..
