Fishers Labs XLT30B Liquid Leak Detector with Multi-Sensor microphone is built to perform, offering advanced electronic amplification and filtering, a tactile keypad, an easy to read digital display and notch feature. The four filtering modes allow the user to adjust the frequency to find the best response.
The Multi-Sensor has superior leak detection capabilities in an extremely compact design, offering improved audio clarity, improved sensor electronics, and better sensitivity to leaks with less background noise. The Multi-Sensor is used for both the ground microphone and direct contact applications.
The notch control allows the user to mask or reject a small range of frequency response. Its purpose is to eliminate a sound (i. e. motor, humming, fans, etc.) that may be interfering with the leak sound. The notch setting can be moved with the arrow keys.
