The DTZ-300WX  Distributed Wireless Data Acquisition System is a modular, multifunctional wireless data acquisition platform. It supports up to 160 temperature sensors and 100 humidity sensors simultaneously. Each channel is independently configurable, with real-time display, automatic result calculation, and full compatibility with temperature and humidity distribution testing in various environmental chambers and equipment. Its compact, portable design makes it ideal for on-site applications.

Product Features:

Fast sampling speed: single-channel sampling speed is less than 0.1 seconds; 16-channel sampling speed is less than 10 seconds.

Long communication distance: Real-time transmission of temperature and humidity data over a wide range and long distance, with a communication distance ≥ 1000 meters (open environment, antenna 1.2 meters above the ground).

Large coverage area: It can connect multiple measurement modules at the same time to realize comprehensive inspection of temperature and humidity in different areas, different equipment and different locations, and improve the timeliness and coverage of monitoring.

Flexible use: supports group measurement, and each group is independent of each other.

Simultaneous correction: complete high-precision correction of multi-module and multi-channel temperature and humidity sensors at one time.

Support verification procedures: Support relevant verification procedures and automatically complete various indicator calculations without the need for host computer software.

Convenient data collection: Each module can independently complete data collection and storage, save data in real time, and support data export.

Real-time refresh: The single acquisition module interface can view all sampling data of the module and refresh it continuously.

Large storage space: built-in 16G memory card.

One machine for multiple uses: One host supports simultaneous detection of multiple experimental equipment; supports simultaneous detection of 160 temperature sensors/100 humidity sensors.

The sensor interface is stable: To prevent the sensor line from disconnecting, the measurement module and the sensor are locked with fasteners.

Supports a variety of temperature measuring elements: Supports thermocouple types: S, R, B, K, N, E, J, T; Thermal resistor: Pt100; Built-in Pt100 cold end compensation.

Low power consumption: Intelligent sleep design maximizes the device standby time while ensuring normal operation.

Alarm function: Built-in intelligent algorithm, according to the set temperature/humidity upper limit value, when the measured value exceeds the set value, the over-limit measurement data will be displayed in red font.

Battery function: built-in lithium battery, charge and discharge protection circuit; intelligent switching of internal/external power supply to extend battery life.

Visual operation interface: Equipped with an intuitive and easy-to-use visual operation interface with clear interface design and reasonable functional layout.
