UNI-T UT334A Geiger Counter & Personal Radiation Detector

UNI-T UT334A Radiation Dose Tester

Portable Ionizing Radiation Monitoring for Medical, Industrial, and Safety Use in Sri Lanka

The UNI-T UT334A is a handheld radiation dose tester designed for real-time monitoring of ionizing radiation. As a featured model in our Radiation Detectors & Geiger Counters collection, this professional device utilizes a highly sensitive Geiger-Müller (GM) counter tube to accurately detect X-ray, Beta (β), and Gamma (γ) radiation, making it an essential tool for health and safety officers across Sri Lanka. Its compact, ergonomic design functions effectively as a personal radiation monitor, ensuring individuals working in high-risk environments can track their exposure levels with precision.

Engineered for practicality, the UT334A simultaneously measures the real-time dose rate and total cumulative dose, displaying a comprehensive safety profile on a clear, 2.0-inch color TFT screen. Whether conducting shielding checks in a Colombo medical facility, monitoring industrial NDT sites in Gampaha, or performing import/export inspections, this tester provides the reliable data needed to maintain strict radiation safety standards. An integrated alarm system immediately alerts users via audible and visual cues if radiation thresholds are exceeded.

Key Features of the UNI-T UT334A

High-Sensitivity GM Counter Tube

Employs an advanced sensor for rapid detection, offering excellent response times for X-ray, Beta, and Gamma rays.

Dual Monitoring Modes

Simultaneously tracks real-time Dose Rate (μSv/h) and Cumulative Dose (μSv), allowing for both instant spot-checks and long-term personal exposure tracking.

Intelligent Alarm System

Features user-definable threshold limits that trigger loud audio and bright visual alarms when radiation levels reach hazardous points.

Data Storage & Timing

Stores up to 10 groups of historical measurement data and features a timing measurement function adjustable up to 999 hours.

Rechargeable Battery

Equipped with a built-in 3.7V 1800mAh lithium battery offering up to 20 days of continuous measurement, easily rechargeable via USB Type-C.

TFT Color Display

A high-definition 2.0-inch color screen ensures all critical safety data is legible in both bright and low-light environments.

Common Applications

Medical & Healthcare Facilities

Frequently Asked Questions

Can the UT334A detect EMF from mobile phones, routers, or 5G?

No. This device strictly measures ionizing radiation (X-ray, Beta, Gamma). It cannot detect non-ionizing electromagnetic fields (EMF). If you need to test cell towers or appliances, please browse our EMF Meters collection.

What is the difference between Dose Rate and Cumulative Dose?

Dose Rate measures the current intensity of radiation at a specific moment, while Cumulative Dose is the total amount of radiation accumulated over a period of time.
