FABISENSE FS204 Refrigerant Leak Detector for HVAC Maintenance Malaysia
FABISENSE FS204 Refrigerant Leak Detector for HVAC Maintenance Malaysia
Content
The FABISENSE FS204 Refrigerant Leak Detector is a portable instrument for locating refrigerant leaks during air-conditioning and refrigeration maintenance. It combines a 40 cm flexible probe, three sensitivity settings, a colour display and audible and visual alerts.
For HVAC contractors and maintenance teams in Malaysia, the main selection points are refrigerant compatibility, detection sensitivity, probe access and operating conditions.
Refrigerant Compatibility
The catalogue lists detection capability for CFC, HCFC, HFC, HFO and refrigerant mixtures, including A2L refrigerants.
This broad compatibility makes the FS204 relevant to enquiries involving different air-conditioning and refrigeration systems. Before ordering, provide the exact refrigerant designation used in your equipment.
The supplied page gives specific sensitivity figures for R134a and R1234yf. Equivalent performance should not automatically be assumed for every refrigerant within the listed families.
Three Sensitivity Settings
The FS204 offers the following sensitivity settings:
SettingCatalogue-listed sensitivityHigh3 g/yearMedium7 g/yearLow14 g/year
Sensitivity expressed in grams per year describes a leak-rate detection specification under defined conditions. It is not a direct measurement of how much refrigerant a system has lost.
The catalogue states maximum sensitivity testing according to EN 14624, with 3 g/year static and dynamic figures for R134a and R1234yf.
For buyers requiring documented performance, request the applicable test report and confirm the test conditions.
Flexible Probe for Restricted Access
The 40 cm flexible probe helps position the sensing tip near joints and components that are difficult to reach with the instrument body.
Potential inspection points include accessible:
Pipe connections
Service valves
Flare joints
Brazed joints
Coil connections
Probe access is particularly useful around compact indoor units and crowded equipment assemblies. Follow the manufacturer's instructions for probe distance, movement speed and preparation before scanning.
The flexible probe assists positioning; it does not establish that every concealed leak can be detected without further access.
Audible and Visual Leak Indication
The FS204 includes a 2.4-inch TFT LCD colour screen and audible and visual alarms.
The illustrated display uses a rising bar indication to show changes in detector response. This supports technicians who need to watch the response while moving the probe around a suspected location.
The catalogue lists a one-second response time and recovery time below eight seconds, with the recovery specification referenced to a 32 g/year environment.
These figures describe specified test conditions. Actual inspection results depend on refrigerant, airflow, background concentration and scanning technique.

Selecting the FS204 for HVAC Work
Air-Conditioning Service Contractors
The FS204 is an option for contractors requiring a portable detector for refrigerant leak-location work. Confirm compatibility with the refrigerants used across your customer equipment.
A clear enquiry should identify the refrigerant, typical equipment type and the smallest leak rate you need to detect.
Commercial Refrigeration Maintenance
For refrigeration service teams, probe flexibility and background recovery behaviour are important when checking multiple nearby connections.
Confirm the manufacturer's procedure for sensitivity selection and handling elevated background refrigerant levels.
Factory and Facilities Teams
Maintenance teams in Selangor, Kuala Lumpur, Johor and Penang can assess the FS204 against their inspection procedures, charging arrangements and required documentation.
The catalogue lists IP54 protection, but users should follow the manual's restrictions for moisture, contamination and cleaning.
A2L and Compliance Documentation
The supplied page lists CE, RoHS, EN 14624:2020 and “A2L certified” among its certification references.
Request supporting documents matching the exact FS204 model where these are procurement requirements.
A2L refrigerant detection capability and hazardous-area approval are separate matters. The catalogue wording should not be expanded into an explosion-proof or intrinsically safe claim without the relevant documentation.
Frequently Asked Questions
Can the FS204 detect R134a?
Yes. R134a is specifically named in the catalogue's sensitivity test information.
Can it detect R1234yf?
Yes. R1234yf is also specifically listed with static and dynamic sensitivity figures.
Does it measure refrigerant pressure?
Pressure measurement is not listed. The FS204 is presented as a refrigerant leak detector.
Does the display show the actual leak rate?
The catalogue provides sensitivity ratings and an illustrated response bar. It does not establish a direct quantitative leak-rate measurement function.
Can it transfer inspection data by USB?
The specification states USB charging only. Data transfer is not advertised.
How long does the battery last?
The catalogue lists five hours. Confirm the test conditions and expected runtime for your use.
Is the sensor guaranteed for ten years?
The page lists an approximate ten-year sensor lifespan. This is not a stated warranty term or a guarantee under every operating condition.
