WINTACT WT3130 vs FNIRSI GC-01 Geiger Counter Which Radiation Detector to Choose Malaysia
If you are looking for a portable Geiger Counter or Nuclear Radiation Detector in Malaysia, the WINTACT WT3130 and FNIRSI GC-01 are two models worth comparing.
Both are designed for portable ionizing radiation monitoring, but buyers should look beyond price and compare the measurement functions, display, alarms and intended application.
This guide compares the WINTACT WT3130 vs FNIRSI GC-01 to help Malaysian users understand which model may better match their radiation monitoring requirements.
WINTACT WT3130 vs FNIRSI GC-01 at a Glance
Both models are portable radiation detectors designed to detect:
Gamma (γ) radiation
Beta (β) radiation
X-ray radiation
This means both can be considered when users need a portable detector for supported ionizing radiation monitoring.
However, their interfaces and feature sets differ.
WINTACT WT3130 Nuclear Radiation Detector
The WINTACT WT3130 uses a Geiger counter sensor and provides both real-time and cumulative radiation measurements.
According to the WT3130 product specifications, its real-time measurement range is:
0–10,000 μSv/h (10 mSv/h)
Its cumulative measurement range is:
0–500,000 μSv (500 mSv)
The specified energy range is:
48 keV–1.5 MeV
Sensitivity is specified as:
80 CPM/μSv (Co-60)
FNIRSI GC-01 Nuclear Radiation Detector
The FNIRSI GC-01 Nuclear Radiation Detector is another portable Geiger counter available from MTM Precision.
GC-01 is designed for gamma, X-ray and beta radiation detection.
The MTM product information lists multiple measurement units, including:
μSv/h
μGy/h
mR/h
CPS
CPM
This makes GC-01 useful for customers who want to view radiation measurements in several formats.

Radiation Types: Which Model Detects More?
For the radiation types specified, there is significant overlap.
WINTACT WT3130
Specified for:
X-ray
Beta radiation
Gamma radiation
FNIRSI GC-01
Specified for:
X-ray
Beta radiation
Gamma radiation
Therefore, radiation type alone may not be enough to decide between these two models.
Users should compare the other functions as well.
Real-Time Radiation Monitoring
The WT3130 provides real-time radiation measurement together with real-time data tracking on its LCD display.
This allows users to observe how the measurement changes during an inspection.
For example, a technician can compare radiation readings between:
Different rooms
Different work areas
Material samples
Equipment locations
Background reference locations
The WT3130 also provides an average measurement display.
Cumulative Dose Monitoring
The WT3130 supports cumulative dose monitoring up to:
500,000 μSv / 500 mSv
Users can also view the starting time of the current dose accumulation.
The WT3130 product information specifies a maximum accumulation duration of:
9,999 hours
This can be useful when users want to monitor accumulated dose over an extended period rather than looking only at the current dose rate.
Measurement Units
Measurement units are another factor to consider.
GC-01 provides several listed display units:
μSv/h, μGy/h, mR/h, CPS and CPM
This may appeal to users who want access to both dose-related readings and detector count-rate information.
The most useful unit depends on the measurement objective.
For general dose-rate monitoring, μSv/h is commonly used.
For observing detector counts, CPM and CPS can provide additional information.
Alarm Functions
Radiation alarms can be useful because operators may not be watching the screen continuously.
WINTACT WT3130
The WT3130 provides:
Sound alarm
Visual alarm
Adjustable alarm settings
FNIRSI GC-01
The GC-01 product information lists:
Sound alarm
Light alarm
Vibration alarm
Therefore, customers who value vibration notification may find GC-01 particularly interesting.
Battery and Charging
Both products are designed as portable rechargeable instruments.
The WT3130 uses a:
3.7V rechargeable lithium battery
and supports:
Type-C charging
The GC-01 MTM product information lists an:
1100mAh rechargeable lithium battery
Battery requirements should be considered if the detector will be used for extended field monitoring.
Size and Portability
The WT3130 measures approximately:
128 × 65 × 27 mm
Its compact dimensions make it suitable for handheld monitoring.
GC-01 is also designed as a portable handheld radiation detector.
For technicians who move between several monitoring locations, portability can be an important consideration.
Which Is Better for Industrial Radiation Monitoring?
The WT3130 is particularly interesting for users who want:
Real-time dose monitoring
Cumulative dose monitoring
Real-time graphical data tracking
Average measurement display
Adjustable alarms
X-ray, beta and gamma detection
Its supplied product information also identifies professional application environments including:
Airports
Customs
Docks
Security organizations
Nuclear power plants
Research institutions
Laboratories
For industrial and institutional customers, these functions make WT3130 a practical model to consider.
Which Is Better for General Portable Monitoring?
GC-01 is attractive for customers who want:
Portable Geiger counter
Gamma detection
X-ray detection
Beta detection
Multiple measurement units
CPM and CPS display
Sound, light and vibration alarms
Rechargeable battery
For general portable radiation monitoring and users who want several measurement formats, GC-01 can be a convenient option.
Which Is Better for Laboratory Use?
Both models can be considered depending on the actual laboratory requirement.
The WT3130 product information specifically identifies laboratories and research institutions as application environments.
Its real-time data tracking and cumulative dose monitoring may be useful for users who want to observe measurements over time.
GC-01 provides multiple measurement units, including CPM and CPS, which may appeal to users who want additional ways to view detector response.
The correct choice should depend on the laboratory's measurement objective rather than simply choosing one model as universally better.
Which Is Better for Material Screening?
Both models can be used for appropriate preliminary radiation monitoring.
Possible screening applications may involve:
Industrial materials
Metal
Scrap materials
Mineral samples
Stone
Equipment
Packages
However, neither detector should automatically be described as an instrument that identifies radioactive isotopes.
A Geiger counter detects supported ionizing radiation; radionuclide identification is a different analytical task.
Can WT3130 or GC-01 Test Seafood and Water?
Both instruments can detect supported ionizing radiation reaching their sensors.
However, neither should be marketed as a device that automatically certifies:
Seafood as safe
Drinking water as safe
Seawater as safe
Food as free from radioactive contamination
Determining the concentration of specific radionuclides in food or water may require controlled sampling and specialized laboratory analysis.
WT3130 and GC-01 are better positioned as portable radiation monitoring and preliminary screening instruments.
WT3130 vs GC-01: Which Should You Buy?
Consider the WINTACT WT3130 if you prioritize:
Real-time graphical tracking
Cumulative dose monitoring
Average measurement display
Adjustable sound and visual alarms
Professional portable monitoring applications
Consider the FNIRSI GC-01 if you prioritize:
Multiple radiation measurement units
CPM and CPS display
Sound, light and vibration alarms
Compact general-purpose portable monitoring
Neither model is automatically better for every application.
The correct choice depends on what you need to measure and how you intend to use the detector.
What About FNIRSI GC-02?
Customers comparing WT3130 and GC-01 should also consider the FNIRSI GC-02 Geiger Counter Nuclear Radiation Detector.
GC-02 uses an Energy Compensation GM tube and supports gamma, X-ray and beta radiation detection.
Its listed applications include:
Food and metal radiation screening
Marble and ore inspection
Nuclear industry environments
Radioactive medical equipment
