Refrigerant Leak Detector
Let’s take a look in this next tool that is very handful when you have maintenance in refrigeration and air-conditioning. This brand is from UNITOR, UNI RX-1A Refrigerant Leak detector is a basic tool use onboard for repair and maintenance. After checking the manual, did you know that it can use in different area besides from air-conditioning and refrigeration?
1. For all halogenated refrigerants that contains Chlorine and Fluorine that includes CFC’s, HCFC’s, HFC’s gasses.
2. It detects Ethylene Oxide gas leaks in hospital sterilizing equipments (halogenated refrigerants).
3. The SF-6 in high voltage circuit breakers.
4. In cleaning agents used in dry cleaning applications such as Perchloroethylene and Halon gases in fire extinguishing system if still fitted onboard these days.
The box contains the leak detector unit, manuals, the battery and spare sensing tip. I will indicate its features also according to the manual written.
1. Microprocessor controlled circuit with Advanced Digital Signal Processing
2. Six segment visual leak size indicator
3. High and Low sensitivity levels
4. One touch reset
5. Tactile keypad controls
6. Real time sensitivity adjustment
7. Detect ALL Halogenated refrigerants
8. Certified SAE J1627 for R12, R22 and R134a
9. Variable frequency audible alarm
10. Constant power indication
11. Cordless and portable, operate in 2 C-cell batteries
12. 14″ (35.5cm) flexible stainless probe
13. Spare sensing tip included
14. CE Approved
15. Carrying case
16. Two year warranty
That a lot of features for this small item, let’s take a look from the unit itself. From top is connected the flexible tube with the sensing tip and protector at the end, then the speaker just below the UNITOR logo, the red LED leak indicators. In the center, we can see the four triangle shape buttons all facing in the center. The top is the Power On/Off, left if “Low” sensitivity button, right for “High” sensitivity button and at the bottom for “RESET” button. The bottom of the handle is the battery compartment and make sure you inserted inwards for Positive Polarity.
Then below is how to operate:
1. Switch the unit ON by pressing the “I/O” (Red/Green) button, all LED’s will light for 2 seconds as the unit performs self check.
2. The unit will begin beeping at a steady rate.
3. Verify the battery level by observing the constant power indicator.
4. Begin searching for leaks. When refrigerant is detected, the audible tone will change to a ‘siren’ type sound, distinctly different from the base beep rate. Additionally, the visual indicators will light progressively.
5. Sensitivity can be adjusted at any time during operation by using HI or LO buttons.
6. If a full alarm occurs before the leak is pinpointed, press the RESET button and start.
I will explain more about the unit for testing:
a. Constant Power Indication allows the user to see the battery level at all times, this is the first LED in the leftmost bar graph. If the light is dim or not lit, maybe the battery should be replaced.
b. RESET button is possible to press anytime, then all LED’s will light for 1 second. These provide a visual confirmation of the reset action.
c. To change the sensitivity, press the LO button key. When the key is pressed, the visual display will momentarily show the four left LED’s red. The base beep rate will slow, indicating Low sensitivity level.
d. To switch back to High Sensitivity, press HI button key. The three right LED’s will light momentarily, and the base beep rate quickens.
If you want to know more about operating tips, you can search their manuals and let’s hunt for any leaks for now. It’s easy and portable to use after reading all printed instruction in manual.
I know there are some other ways to check for any leaks like the special gas for torch that the flame color will changed when gas id detected, spray foam in a can and the old way use of bubble soap. It depends on you what tool is comfortable and convenient way.
I’m not paid to review or promote these equipments from the company. I just want to share my experience.
Have you use this one before? Share your experience.
