Explore is the newest generation hand held xrf analyzer, it is the best hand held XRF analyzer with many features that you cant find in the markets and other brands
The features of Explores are as below:
1. Best SDD detector in the world:it equiped with the best SDD detector-fast SDD detector, that enable to analyze light elements directly without helium asist from Mg U
2. more powerful data library:it can test rare earth elements and enable to test 34 elements simultantaneously
3. more safety design, there is insurance lock key to gurantee the safety for operator and invoid mis operate
4. non power off design, the analyzer works 5 minutes even you take the battery off the analyzer, which offer you enough time to change battery and finish testing once the battery power off
5. 3 color light system: there are green, red and yellow light system to show you the working status of the analyzer
6. operator and expert mode system easy to switch
7, 3 seconds fast scan for metal alloy and stainless steel
