When working in hospitals, industrial factories, laboratories, or radioactive inspection sites, real-time radiation monitoring is non-negotiable for personal safety. Today we’re introducing the LDT-200G personal radiation dose alarm device, a compact, high-sensitivity radiation detector upgraded for full-scenario radiation protection.
Built around a high-speed low-power embedded microprocessor, the LDT-200G adopts a highly sensitive GM counter as its core detector. It supports simultaneous detection of X-rays, gamma rays and hard beta rays, covering nearly all common ionizing radiation encountered in daily industrial and medical work.
This portable dosimeter serves two core testing purposes: measuring ambient dose equivalent rate (DER) and total accumulated ambient dose equivalent (DE) of X & gamma photon radiation.
1. Personal daily radiation protection: Real-time cumulative dose and dose rate alarm for staff exposed to radioactive environments
2. On-site radiation inspection: Radiation level testing of construction materials, lab samples and environmental surroundings
3. Institutional monitoring: Regular radiation measurement for hospitals, manufacturing plants, schools and research labs
· Clear Backlit Dot Matrix LCD Screen: Large display to show dose rate and total cumulative dose at a single glance, readable in dark environments
· Powerful Data Storage: Stores up to 98,300 real-time monitoring records and 32,760 alarm logs. Data can be exported via USB with matched dedicated software; Bluetooth connection and mobile APP reading are available as optional upgrades
· Long-Lasting Rechargeable Battery: Built-in 3.7V 900mAh lithium battery with real-time battery voltage display, charged conveniently via universal Type-C USB port
· Flexible Safety Alarm: Fully adjustable radiation alarm threshold across the entire measurement range, with fast protective alarm response within 5 seconds
1. Dose Equivalent Rate Range: 0.01μSv/h ~ 5000μSv/h; extended maximum range of 1Sv/h optional
2. Cumulative Dose Measurement Range: 0.00μSv ~ 9999Sv
3. Detectable Photon Energy Spectrum: 25keV ~ 3.0MeV
4. Measurement Accuracy: Energy response error ≤ ±30% (referenced to Cs-137); relative measurement error ≤ ±10% at 10μSv/h (Cs-137 source)
5. Working Conditions: Operates stably from -30℃ to +50℃, withstanding relative humidity up to 95% under 40±2℃
6. Portable Size & Weight: Compact body at 102×62×28mm, lightweight at only 100g, easy to clip or hang on your body with the matched lanyard
Each complete set includes the LDT-200G host device, carrying lanyard, Type-C USB charging cable, user manual and official warranty card.
All technical specifications listed are for reference only; actual parameters shall prevail based on the specific product model you order.
