Functional features
1.High accuracy and fast measurement
DTZ-300BX1609G Intelligent temperature and humidity inspection instrument can quickly collect data from each channel while ensuring 0.01 level accuracy, which greatly improves work efficiency while ensuring measurement accuracy.
2.Intelligent human-computer interaction interface
It adopts high-definition intelligent capacitive touch screen, which is simple and convenient to operate. It can display the collected data in real time and the battery power in real time. General parameters such as temperature sensor type, number of temperature sensor channels, number of humidity sensors, date, time, and collection interval support custom settings.
3.Convenient data collection
There is no need for a PC at the work site. The multi-channel data collector can independently complete data collection and storage, and the data is stored in a USB flash drive in real time. After the collection work is completed, the U disk can be inserted into the computer to complete the display and analysis of the data.
4.Supports 8g large-capacity U disk storage function
Sampling data supports real-time storage to USB flash drive. The stored data can be browsed or processed with general tool software such as Excel, or it can be imported into special software for data analysis, report generation and certificate output.
5.Auto correction function
It supports the linear correction function of commonly used K, N, and S thermocouple temperature sensors, supports the linear correction function of Pt100 thermal resistance sensor, supports the linear correction function of humidity sensor, and supports the introduction and saving of multi-point temperature correction values in a single channel.
6.Communication function
Supports connection to PC via data cable, supporting professional database management software, intelligent data management, real-time curve display of temperature and humidity information of each channel, test data of each channel: marked center point, fluctuation, uniformity, change rate, current detection progress, equipment Status, etc., supports multiple inspection instruments to carry out testing work at the same time, and the data is processed independently, effectively improving work efficiency.
7.Commonly used channels ensure basic applications and meet regulatory requirements
The host supports 16-channel temperature sensors and 9-channel humidity sensors to meet most application scenarios, and can calibrate multiple cabinets at the same time, saving valuable on-site inspection time.
8.Simple and fast connection method
The wiring method uses standard connectors as connectors, making sensor wiring easier and faster. The temperature and humidity interfaces have anti-misplugging functions, effectively ensuring the reliability and performance indicators of system connections.
9.The system supports a variety of temperature measurement components
Including thermocouples: S, R, B, K, N, E, J, T; thermal resistance: Pt100. The company can provide a variety of temperature sensors with special specifications to meet the needs of different occasions.
10.Professional cold end compensation processing
Imported external four-wire PT100 is used as the cold end compensation of the thermocouple measurement channel. In the thermocouple inspection mode, the reference terminal compensation temperature error is better than 0.2℃, and the error between channels is better than 0.1℃.
11.Built-in large-capacity lithium battery, low power consumption and long-lasting battery life
Built-in large-capacity lithium battery, low power consumption design, supports 30 hours of continuous operation. The charging interface is 2.1×6.4DC, with reliable connection and large charging current. It has a battery charge and discharge protection circuit, which is safe and reliable; the external power supply and the battery intelligently switch the power supply to extend the battery life.Temperature data is automatically saved to the U disk.
Computer software features
1.Inspection information management function: Manage customer unit information and inspection equipment information without having to repeatedly enter data every year.
2.Simultaneous measurement of multiple devices: Supports simultaneous detection of multiple devices being inspected, and data is processed independently to improve detection efficiency.
3.Intelligent data selection: automatically analyze the collected data and intercept the available data.
4.Intelligent breakpoint and resume inspection: supports the breakpoint and resume inspection function, multiple inspections of the same device, and intelligent synthesis of reports.
5.Intelligent data management: Intelligent management and quick query of historical inspection submission information.
6.Real-time curve display: Display the temperature and humidity information of each channel in real time and display it in the form of a curve.
7.Real-time status display: real-time display of each channel data, marking center point, fluctuation, uniformity, change rate, current detection progress, equipment status and other information.
