DTZ-300BW Smart Multi-Channel Temperature and Humidity Data Acquisition Logger
Introduction
Key Features
7-Inch Industrial Color Touchscreen
Displays real-time data across all 24 high-precision 24-bit sampling channels.
Flexible Channel Configuration
Each of the 24 channels can be individually set to thermocouple, RTD, humidity sensor, or analog signal mode.
Dedicated Cold Junction Compensation
Each thermocouple channel includes its own internal cold junction sensor and independent sampling circuitry for high precision; all modules are designed for < ±0.1 °C measurement accuracy.
Customizable Sensor & Sampling Parameters
Supports editing of sensor type, range, sampling time, and interval on a per-channel basis.
Advanced Calibration Options
Each channel supports single-point, segmented linear, or least squares curve calibration.
Optimized Analog Signal Design
High-accuracy measurement of analog and reference signals meets the stringent demands of precision electrical metrology.
Multiple Data Formats Supported
Real-time display, storage, and output of voltage, resistance, temperature, and humidity data.
Secure Data Encryption
Built-in encryption algorithm supports secure data file protection.
Versatile Communication Options
Supports RS232, wired LAN, and wireless communication with both PC and mobile interfaces.
Integrated Power Supply for Sensors
Provides 24 channels of 5V output, simplifying connection for humidity sensors.
Large Internal Storage
8 GB of internal memory for data storage; data export supported via USB interface.
