FNIRSI GC-01 vs GC-02 Geiger Counter Which Nuclear Radiation Detector to Buy Malaysia
When comparing portable nuclear radiation detectors, FNIRSI GC-01 and FNIRSI GC-02 are two Geiger counter options available from MTM Precision in Malaysia.
Both are designed for portable ionizing radiation monitoring and support gamma, X-ray and beta radiation detection.
However, buyers should consider the detector functions, battery capacity, alarm features and intended application before choosing between them.
This guide compares FNIRSI GC-01 vs GC-02 for customers looking for a Geiger Counter or Nuclear Radiation Detector in Malaysia.
FNIRSI GC-01 vs GC-02: What Do They Detect?
According to the MTM Precision product information, both models support:
Gamma (纬) radiation
X-ray radiation
Beta (尾) radiation
Both models use an Energy Compensation GM Tube.
Therefore, customers should not choose between GC-01 and GC-02 based only on the radiation types listed.
The other features and intended application should also be considered.
FNIRSI GC-01 Nuclear Radiation Detector
The FNIRSI GC-01 Nuclear Radiation Detector is a portable Geiger counter designed for radiation monitoring.
Its listed measurement units include:
渭Sv/h
渭Gy/h
mR/h
CPS
CPM
The GC-01 also provides several alarm methods:
Light alarm

FNIRSI GC-02 Geiger Counter
The FNIRSI GC-02 Geiger Counter Nuclear Radiation Detector is another portable model available from MTM Precision.
Like GC-01, it uses an Energy Compensation GM Tube and supports gamma, X-ray and beta radiation detection.
Its listed battery capacity is:
850mAh
The MTM product page also identifies several application areas for GC-02.
These include:
Food & Metal Detection
Marble & Ore Inspection
Nuclear Industry
Radioactive Medical Equipment

GC-01 vs GC-02 Battery Capacity
Battery capacity is one clear specification buyers may want to compare.
FNIRSI GC-01: 1100mAh
FNIRSI GC-02: 850mAh
Based on the listed capacity alone, GC-01 has the larger battery.
However, battery capacity should not automatically be translated into an exact operating-time advantage without considering factors such as display usage, alarm activity and instrument power consumption.
Which Model Is Better for Multiple Measurement Units?
GC-01 is particularly interesting for users who want several displayed radiation measurement formats.
The MTM GC-01 product page lists:
渭Sv/h, 渭Gy/h, mR/h, CPS and CPM
CPM means Counts Per Minute, while CPS means Counts Per Second.
These count-rate displays may be useful for users who want to observe detector counts in addition to dose-related measurements.
Which Model Is Better for Material Screening?
The GC-02 product information specifically highlights applications involving:
Food & Metal Detection
and:
Marble & Ore Inspection
For customers working with metal, natural stone, mineral materials or related screening applications, GC-02 therefore has a particularly relevant application positioning.
However, these descriptions refer to radiation detection or screening.
GC-02 is not a conventional metal detector and does not identify the chemical composition of marble, ore or metal.
Which Model Is Better for Nuclear Industry Applications?
The MTM GC-02 product page specifically lists:
Nuclear Industry
as an application.
This makes GC-02 relevant for customers searching for a portable radiation detector associated with nuclear-related environments.
However, professional nuclear facilities may require specialized radiation survey instruments depending on the measurement objective and regulatory requirements.
A portable Geiger counter should not automatically be considered a replacement for every professional radiation monitoring system.
Which Model Is Better Around Radioactive Medical Equipment?
GC-02 also lists:
Radioactive Medical Equipment
among its applications.
This may make GC-02 interesting for general portable radiation monitoring around appropriate technical or medical environments.
However, formal medical equipment radiation safety testing may require specialized calibrated survey instruments, defined procedures and qualified personnel.
GC-02 should therefore be selected according to the actual monitoring requirement.
Which Model Is Better for General Portable Radiation Monitoring?
GC-01 has a strong general-purpose feature set.
Its combination of:
Gamma detection
X-ray detection
Beta detection
Multiple measurement units
CPM
CPS
Sound alarm
Light alarm
Vibration alarm
1100mAh battery
makes it an attractive option for users who want a portable Geiger counter for general radiation monitoring.

Can GC-01 and GC-02 Measure Background Radiation?
Both products are designed for ionizing radiation monitoring.
A portable Geiger counter may therefore show a reading even when there is no known radioactive source nearby because background radiation exists in the environment.
Users performing preliminary screening should first understand the normal background reading at the monitoring location.
Measurements around the area or object being investigated can then be compared with that reference.
Can GC-01 or GC-02 Detect Radiation in Food?
A Geiger counter can detect supported ionizing radiation reaching its GM tube.
However, this does not mean it can automatically determine:
Which radionuclide is present
The concentration inside food
Whether food complies with a regulatory limit
Whether food is officially safe for consumption
Therefore, GC-01 and GC-02 should be used within their radiation-monitoring capabilities.
Where quantitative radionuclide analysis is required, appropriate laboratory testing may be necessary.
Can GC-01 or GC-02 Detect Radiation in Water?
The same principle applies to water.
A handheld Geiger counter can detect supported ionizing radiation reaching its detector, but it does not automatically quantify individual radionuclides dissolved in a water sample.
Questions involving regulatory assessment of:
Drinking water
Seawater
Wastewater
Food samples
may require specialized laboratory analytical methods.
GC-01 vs GC-02 for Marble and Granite
GC-02 has a clear advantage in product positioning because its listed applications specifically include:
Marble & Ore Inspection
Customers involved in:
Marble
Granite
Natural stone
Minerals
Ore
may therefore find GC-02 particularly relevant for preliminary radiation screening.

GC-01 vs GC-02 for Scrap Metal
GC-02 also lists metal radiation screening among its applications.
For scrap metal, recycling or industrial material screening, a portable Geiger counter can be used to investigate detectable ionizing radiation.
However, shielding, distance and source position can affect detection.
A handheld detector should not be assumed to guarantee detection of every radioactive source hidden inside a large scrap load.
High-volume recycling facilities may require specialized radiation monitoring systems.
What About the WINTACT WT3130?
Customers comparing GC-01 and GC-02 can also consider the WINTACT WT3130 Nuclear Radiation Detector.
According to the supplied WT3130 product information, it detects:
X-ray
Beta radiation
Gamma radiation
Its real-time measurement range is:
010,000 渭Sv/h (10 mSv/h)
Its cumulative range is:
0500,000 渭Sv (500 mSv)
The specified energy range is:
48 keV1.5 MeV
Sensitivity is specified as:
80 CPM/渭Sv (Co-60)
WT3130 also provides real-time data tracking, average measurement display and adjustable sound and visual alarms.
GC-01 vs GC-02 vs WT3130
The three models can be positioned differently.
FNIRSI GC-01
Consider GC-01 when you want:
General portable radiation monitoring
Multiple measurement units
CPM and CPS
Sound, light and vibration alarms
1100mAh rechargeable battery
FNIRSI GC-02
Consider GC-02 when the listed application positioning is particularly relevant, including:
Metal radiation screening
Marble and ore inspection
Nuclear industry environments
Radioactive medical equipment
WINTACT WT3130
Consider WT3130 when you want features including:
Real-time radiation monitoring
Real-time data tracking
Average measurement display
Cumulative dose monitoring
Adjustable sound and visual alarms
The best choice depends on the actual application.
Which FNIRSI Geiger Counter Should You Buy?
For customers primarily looking for a general portable detector with multiple measurement units and a larger listed battery capacity, GC-01 is worth considering.
For customers particularly interested in the application areas highlighted for metal, marble, ore, nuclear industry and radioactive medical equipment, GC-02 is worth considering.
Neither model should automatically be considered universally better.
Choose according to the required functions and application.
