PROXGRIND RFID Field Detector Tiny Frequency Detection Card Keychain Mobile Phone IC ID Access Control Readhead Testing

PROXGRIND RFID Field Detector Tiny Frequency Detection Card Keychain Mobile Phone IC ID Access Control Readhead Testing Description

1. Using 6-layer board technology, low-frequency coil has high Q value, high sensitivity, and long luminous distance.
2. High frequency uses diode voltage doubler circuit, which has high sensitivity and long luminous distance.
3. Low frequency and high frequency are placed in a staggered manner, and they do not weaken each other in the smallest volume, ensuring the best performance in a small size.
4. Using epoxy resin drip glue technology, it is waterproof and moisture-proof, wear-resistant and drop-resistant, and can be carried with you

This is an ultra-sensitive field strength detection card that integrates high frequency and low frequency. It can be used to detect the card reading frequency and signal strength of the access control reader. It is an indispensable tool for lock matching, access control installation, and RFID debugging.
The RFID Field Detector detects and displays the presence of Low Frequency (125KHz) and High Frequency (13.56MHz) fields.
Designed to be compact and discrete, it fits neatly onto your keyring. The RFID Field Detector is an indispensable tool.
When in the presence of an RFID field, an LED indicates the frequency of the field.
