The FNIRSI GC-02 is a pocket Geiger counter and direct-reading radiation dosimeter for mobile beta, gamma and X-ray awareness. It combines current dose rate, accumulated dose, timed monitoring and recent record storage in a compact belt-wearable format.
The GC-02 may suit personal travel checks, household screening, environmental observation and general workplace awareness. It should not be represented as a regulated occupational dosimetry service without confirmation of the exact unit, calibration route, wearing method and local compliance requirements.
Sourcing status: A public Chinese manufacturer or domestic retail route has been identified for this named model. Before accepting an order, NRD verifies the seller, exact revision, package contents, quantity, supporting documents and current commercial terms.
We will verify the current domestic seller, exact model revision, package, documents, MOQ, lead time and commercial terms before quotation.
These values are translated and rewritten from the named manufacturer’s public product information. They are useful for initial comparison, but the current data sheet, detector revision, test conditions and exact configuration must be confirmed before ordering.

Confirm the detector tube, hardware revision, firmware, interface language, accessories and package contents. Marketplace listings can combine different revisions under one title.
State the radiation type, expected dose-rate range, units, background, alarm method and operating environment. A portable awareness meter is not automatically suitable for regulated dosimetry.
Name the required data sheet, calibration field, standard, issuing laboratory, traceability and report language. No certificate is claimed until the supplier provides it for the quoted unit.
Confirm sample quantity, MOQ, lead time, packaging, Incoterms, warranty, spare units and after-sales route before payment.
Yes. A public manufacturer or Chinese domestic retail route has been identified. The exact seller, model revision, package and availability are checked again before quotation.
Stock is not claimed on this website. Current availability, quantity and dispatch time are confirmed for each enquiry.
Documentation depends on the seller and package. State the required standard, laboratory and destination-market requirements so the correct evidence can be quoted.
English labels, packaging, accessories and OEM options can be reviewed for qualified quantities. Feasibility, samples and MOQ require supplier confirmation.
A gas-filled detector that produces pulses when ionizing radiation interacts with the tube.
Dose rate describes the indicated radiation dose per unit of time, commonly shown in µSv/h.
Accumulated dose is the total indicated dose recorded during a monitoring period.
Energy response describes how detector sensitivity changes across photon energies.
Calibration evidence records how a specific instrument was tested against stated references and conditions.
Share your application, required quantity and any OEM requirements. We will review the request and reply with suitable product information and a quotation.
