ZK-BOX3833 UHF RFID Inventory Box
Fully enclosed Intelligent scanning with precise stray-read prevention

1000 Tags/sec Ultra-Fast Inventory; suitable for logistics warehousing, retail, and library/archive management.

The ZK-BOX3833 UHF RFID Inventory Box is a fully enclosed intelligent RFID scanning device designed for multi-industry scenarios. The ZK-BOX3833 features a built-in high-performance RFID reader module and combines independently developed efficient signal processing algorithms to achieve rapid tag inventory while effectively shielding signal interference from tags outside the cabinet, ensuring "inventory only inside the box, and inventory with precision."
It’s widely used in logistics warehousing inbound and outbound operations, retail store inventory, library archive management, medical linen counting, jewelry inventory, tool management, and fixed asset inventory, helping enterprises significantly improve inventory efficiency and reduce labor costs.

 Precise Stray-Read Prevention — Enclosed Cabinet + Signal Algorithm Dual Guarantee
The fully enclosed metal cabinet physically isolates external signals, and together with the exclusive efficient signal processing algorithm, under the dual effect it completely eliminates tag stray-read problems around the cabinet. However many are placed, that many are counted, and with that accuracy.  No more worries about "scanning too many, scanning the wrong ones."

2️⃣ Thousands of Tags per Second Ultra-Fast Inventory — Efficiency Increased by More Than 10 Times 
Max Inventory speed up to 1000 tags/sec. A whole box of goods can be read as soon as it is placed inside, completing one box inventory in seconds. Compared with manual handheld scanning, inventory efficiency is increased by more than 10 times, greatly reducing labor input and time costs. ‌

3️⃣ -86dBm Ultra-High Sensitivity — Small Tags and Weak Signals Are All Captured
High receiving sensitivity design. Even for small-sized tags, tags near metal/liquid, and tags attached in complex positions, it can still identify and read stably, reducing the missed-read rate and improving inventory data accuracy.

4️⃣ Industrial-Grade Wide-Temperature and Wide-Humidity Design — Stable Even in Harsh Environments
-20℃ to +60℃ operating temperature range, normal operation in 95% humidity environment. Whether in cold storage, high-temperature workshops, or humid underground warehouses, the device can continue to operate reliably, with low failure rate and long service life.

5️⃣ Flexible Interfaces + Full-Stack Development Support — Quickly Connect to Your System
RS232 + TCP/IP standard interfaces, optional WIFI wireless communication, meeting the needs of different deployment scenarios. Provides complete communication protocol, DLL dynamic library, and demo software, supports Windows and Android dual-platform development, with short integration cycles and low development costs.

6️⃣ Adjustable Power + Customizable Frequency Bands — One Device Adapts to the Global Market
RF Output power 0-33dBm continuously adjustable (step ±1dBm), can be flexibly set according to tag type and usage scenario. Supports frequency band customization for various countries, so one device can meet the needs of both domestic and overseas markets.
