Best Accutrak in 2026

NSF certified for use around food

Non-Corrosive

Detects Micro Leaks down to 0.65 oz/year

MEASURE BACKGROUND LEVEL: Pyle carbon monoxide meter detects the presence of carbon monoxide (CO) and measures concentrations between 1-1000 parts per million (PPM). Accuracy: +/- 15% or +/- 10 PPM in a 0-50º C operating temperature

AUTO POWER OFF: The carbon monoxide meter features automatic shutdown to help conserve battery life. The 9v battery will supply the power of carbon monoxide meter. The battery completes the package

LCD DISPLAY: The backlight of the carbon monoxide meter will light once the button is press. It displays the level of carbon monoxide the unit is sensing. It has an LCD display, so it works great even in poor lighting condition

High-precision Heated Diode Sensor: It triggers on R11/R22/R404a/R410a/R600a/R1234yf and all halogenated refrigerants including CFCs, HFCs, HCFCs, HCs, HFOs and blends.

4 Simple Buttons: It allows to fast reset, mute, power on/off, adjust sensitivity and makes LED screen visually display the leakage level and device status.

Fast Response: Warms up in the 30s and respond in 3s; 6-grade adjustable sensitivity with maximum sensitivity 0.11oz/yr.

🔬 ACCURATE: Professional and Accurate OXYGEN (O2) gas detector, 0-30.0% with 0.1% resolution. USA NIST Calibration.

🌷 DETECT: Electrochemical cell sensor with accuracy: ≤±5% F.S. and response time: T<30s. Zero and span calibration options. Comes factory calibrated.

🎆 ALARMS: Adjustable audio, visual, and vibration alarms alert when preset levels are reached. Alarm digital time stamp and logging.

The Ultrasonic Leak Detector can quick and simple location ultrasonic caused by air, liquid, dust leak. It’s able to detect leakage on tyre and also detects ultrasound as well. Use ergonomics, it is easy and fast for user to use with simple key operation mode and comfortable hand feeling.

The Air Leak Detector is a very useful device to locate leak either under pressure or vacuum. The head phone produced a very distinct sound on the area where the leak is coming from. Using the transmitter, it will transmit sound from an enclosed area and can pinpoint the gaps or opening on the roof using the receiver.

The Ultrasonic Leak Finder can detect the air or liquid leakage by detecting ultrasonic caused by high pressor leakage.It can trace the detector around outside of the screen, windows and door seals to locate the leak. It uses the advanced ultrasonic sensing technique and features small size, light weight, reliable detection, easy use and utility.

【WIDELY APPLICATION】The electronic stethoscopes is a very useful diagnostic test tool which can reduce downtime and maintenance related costs of the tested equipments.Air/Vacuum Leaks;Gas and Liquid Turbulence;Electrical Discharge;Mechanical Wear;Sound Generation.A practical and portable tool for any pressure and vacuum system.

【THE RECEIVER PERFORMANCE】allsun pro ultrasonic leak is mechanics electronic stethoscope, the receiver is sensitive to ultrasonic in the frequency range of 36k to 44kHz Audio feedback and a 10 bar LED indicator for visual intensity of signal, 33mm directional receiver port, 3.5mm stereo jack and a rotary on/off volume control switch.

【ACCURATE & RELIABLE】Pro Ultrasonic Leak Detector Kit,the 30cm air probe serves to extend reach or to facilitate isolating a leak among multiple suspect areas.This Ultrasonic Diagnostic Tool is easy to carry and operate, and its detection result is accurate and reliable.

【Quick Leak Location】Ultrasonic leak detector adopts advanced ultrasonic sensing technology, which is specially used to detect the leakage of gas, liquid, etc. Air leak detector can quickly and accurately find gas or liquid leaks in various pressure or vacuum systems. Ultrasonic leak detector can be used to detect the tightness of cabins, car cockpits, refrigerators, containers, etc., and can also be used to track and locate leaks in doors and windows, pipes, tires, and refrigeration equipment.

【High Sensitivity Sensor & Adjustable Sensitivity】Ultrasonic leak detector adopts advanced high-quality sensor with high sensitivity, which can respond quickly and detect tiny leaks, providing you with stable and high-precision detection. The sensitivity of the ultrasonic air leak detector can be manually adjusted according to the detection environment. Adjust to the required sensitivity, the measurement accuracy will be higher (Frequency Response: 40KHz ± 2KHz).

【Sound & Light Dual Alarm Prompt】When ultrasonic waves are detected, the LCD indicator of the ultrasonic leak detector will light up, and ultrasonic leak detector will issue rapid ticking sounds to remind you at the same time. Our ultrasonic leak detector comes with a headset that quickly captures the location of leaks with even the tiniest of sounds. The closer the probe is to the leak, the faster the frequency and the higher the pitch of the ticking sound in the headset.
