DH4215 is the anti-metal tag designed for hostile environment, which could resist corrosion and high temperature for a very long time period. The heat withstanding is up to 250 degree centigrade.
DH4215 passed the following tests: high temperature test, alternating temperature test, corrosion (acidity/ alkaline) testing, vibration test, Ultrasonic washing test. 
And to make sure each shipment tags with excellent reliability and performance consistency, we do a series of tests before shipment, include testing by European tags comprehensive test instrument, encoding test of EPC and User memory.
Mounting options on metal surface: 3M glue/ Screw/Rivets/Double sides adhesive that adaptive to mounting conditions.
