	Description: This instrument is a new generation of fully automatic intelligent leak detector. The high-tech central micro-processing unit is the core of this product, and its digital signal processing capability can better manage the circuit and process the detection signal. Due to the extensive use of integrated circuits, the number of components in the circuit has been reduced by 40%, greatly improving efficiency and performance. The microprocessor monitors the probe and battery voltage at a rate of 4000 times per second, and extremely small signals can also be captured. This makes it stable and reliable in almost any environment.

Adjustable 6 Levels (32X) Sensitivity The leak detector hvac provides a 32-fold sensitivity increase from 1 to 6 levels. Sensitivity can be adjusted with the sensitivity button, doubling or halving each press. The higher the sensitivity, the faster the sound frequency. Adjust to the required sensitivity according to the detection environment, the measurement accuracy of the halogen gas leak detector hvac will be higher.	Sound and Light Dual Alarm When the gas is detected, the red indicator of freon leak detector will light up and the refrigerant leak detector hvac will emit a buzzing warning. The higher the concentration of leaking gas, the more red lights will be on, and the sound frequency of the alarm will be faster.

High Sensitivity & High Precision This refrigerant leak detector uses a high-sensitivity sensor, and a built-in mechanical pump pumps air for sampling, providing a positive airflow for the probe sensor, so it can fast respond and detect tiny refrigerant gas. Freon leak detector is controlled by a microprocessor with advanced digital signal processing capabilities to provide you with high accuracy of detection, bringing you high stability and reliability.	Specification: Power Supply: 3V DC: 2pcs "C"cell Alkaline batteries (battery not include) Maximum Sensitivity: Certified for R12, R 22, R134a @ 05 oz/yr (14gr/yr) Ultimate sensitivity: less than 0.1 oz/yr(3gr/yr)for all Halogen based refrigerant. Sensing Tip Life: Approx. 20 hours Operating temperature: 30F-125 F (0-52C) Duty Cycle:continuous,no limitation Response Time: Instantaneous Reset Time: one second Warm-Up Time: Approx. 7 seconds Unit Weight: 1.01 Ibs (560 grams) Unit Dimensions: 9.2" x 2.8" x 1.95"(24.2cm x 71.5cm x 50cm Fixed Probe Length: 14"(35.5cm)

Environment Reset Function

After pressing "reset" button, freon leak detector will automatically set to ignore the refrigerant concentration on probe sensor, and will only alarm when the refrigerant concentration is higher than the current environment. This feature helps you efficiently track down higher-concentration leaks. (Note:The device automatically turns on the environment reset function by default when starting up. It is recommended to start up in fresh air without refrigerant leakage).

Battery Test & 14" Flexible Stainless Steel Probe
Bright LCD lights indicate the degree of leakage in a progressive manner, clear at a glance, helping you to quickly identify. It is also used to display the sensitivity level and battery level, remind you to replace it in time. Stainless steel probe tube of refrigerant leak detector is 14inch/35.5cm long and can be bent at will, so the position of the leak can be easily accessed and detected even in difficult and hard-to-reach areas.

Soft-touch Button & Portable Toolbox
HVAC leak detector is equipped with a touch button for easy operation, and the handle is ergonomically designed and covered with rubber, making it comfortable to grip. Leak detector hvac also comes with a toolbox, which is convenient for you to carry around.

Note:
1. When the leak cannot be detected, the sensitivity should be increased. Only lower the sensitivity when resetting does not "reset" the instrument.
2. If the leak detector alarms after it is turned on, press the reset button to reset the circuit.
3. In heavily polluted areas, the instrument should be reset in time to eliminate the impact of the environment on the instrument. Do not move the probe while resetting. The instrument can be reset as many times as required.
4. In windy areas, even large leaks can be difficult to find. In this case, it is best to screen the potential leak area.
5. The tester may alarm if the probes come into contact with moisture or solvents, so avoid touching them when checking for leaks.
6. The probe can be cleaned with a mild detergent such as alcohol, do not use solvents such as gasoline, mineral oil, etc., because they will remain on the probe and reduce the sensitivity of the instrument.
