The summary of the system:

DTZ-85W wireless temperature and humidity inspection system uses high-precision, high-stability temperature and humidity sensor, Zigbee wireless communication network, wifi (network cable, RS-485) connection display terminal, high temperature measurement accuracy, convenient layout, stable operation, display Intuitive, report smart. It is widely used in the calibration or calibration of temperature and humidity parameters of constant temperature and humidity chambers (houses), incubators, refrigerators, grain depots, tobacco warehouses, large-area constant temperature and humidity rooms, etc. The temperature field, the uniformity of the humidity field, the fluctuation degree, etc. are automatically tested and analyzed and a report is generated.

Features:

Accurate measurement: the temperature is imported temperature and humidity sensor, the temperature measurement accuracy is better than 0.1℃, humidity is 0.8% RH

Convenient location: wireless transmission, no need for long-distance wiring, convenient on-site measurement

Offline measurement: Data can be offline and recorded offline in the main station, and uploaded to the system software after booting.

Automatic analysis: automatic analysis of the highest point, lowest point, uniformity, and volatility of the temperature and humidity field

Real-time curve: The computer software can simultaneously display real-time curves of up to 32 sensors in real time.

Alarm monitoring: temperature detection function, can monitor the ambient temperature and humidity, set the alarm upper and lower threshold, exceed the automatic alarm

Remote transmission: remote detection of temperature distribution in the 1200m range (no occlusion visible distance)

Multi-point measurement: A single acquisition base station can support up to 255 temperature measurement points at the same time, supporting 32 acquisition base stations simultaneously

Intelligent report: report can be automatically generated according to the rules

Wide temperature range: can be used in -40-85 ° C environment, still maintain high accuracy measurement results

Multi-terminal support: It can read data from tablet, notebook and desktop, and support 4 terminals to read the master data at the same time.

Portable and durable: battery powered, no external power supply, small size, easy to install

Ultra low power consumption: low power design,Lithium battery powered, long use time.

Application scenario

Scene 1, temperature and humidity field measurement:

It is used for temperature and humidity check box (standard box), environmental test chamber, environmental laboratory, incubator temperature and humidity uniformity, fluctuation measurement and calibration.

According to requirements of the regulations, the sensors are distributed, and the data of each sensor is wirelessly transmitted to the main station. After analyzing the data, the main station transmits the data to the temperature field measurement software on the notebook/desktop/tablet in real time, and the software displays the current sensor real-time data. And display the temperature curve, and according to the requirements of the procedures for data recording and analysis, and finally issue a report.

The tablet, the main station and the sensor are all powered by the battery, which is convenient to carry, especially suitable for out metering and verification.

Scene 2, temperature and humidity online / offline monitoring:

It is used in large areas with limited temperature and humidity conditions such as grain storage, tobacco warehouse, cold storage, ammunition depot, equipment room large area。Temperature and humidity data in the online/offline monitoring space, saves detected historical data, real-time over-range alarm , calculate the volatility, uniformity.

The scheme is suitable for measurement in multiple warehouses (temperate zones), and each temperature zone is far apart. One main station can be arranged in each temperature zone, and each temperature zone is connected by RS-485 bus, network cable and optical cable, and the data is remote. After transmission to the temperature monitoring room, after setting the alarm threshold, all temperature and humidity data can be monitored online in real time.

Technical indicators：

Master Station

Main feature：

• The use of the site can complete data collection, storage, etc. by itself without the host computer;
• The system host uses a 3.5-inch color touch screen to operate and configure, and simultaneously displays current data in real time;
• The system host can use USB interface to communicate with the upper computer to complete data transmission, real-time data and curve display;
• The system probe can also communicate wirelessly with the PC directly (the PC needs external module support).
