◆ purpose and scope of use
ZDR Series intelligent temperature and humidity data logger is the agricultural research, food, medicine, chemical industry, meteorology, environmental protection, electronics, laboratory and other fields on the various climate parameters for monitoring and recording equipment.
The recorder system I plant to learn the advantages of similar products abroad, combined with the characteristics of China independently designed, temperature and humidity can be recorded and other climate parameters. Internal or external use of various sensors, the sampled data stored in the recorder memory. The data collected records can be transmitted to a computer.
ZDR Series intelligent temperature and humidity data logger with high-energy lithium battery powered, no external power supply, compact and portable (58 × 72 × 29), machine power consumption.
◆ Features
Long tradition of recording the temperature and humidity data is commonly used in manual records or ordinary recorder to record on paper with ink drawing curves, its bulky, low precision, easy to plug the ink, time and effort,. Subsequently the detection apparatus, paperless recorder also because of their size, high cost, need of external power, but not in extensive use in agricultural research.
The recorder with built-in smart chip with 12Bit A / D converter, LCD display, intelligent recording, remote communications, with international brands of sensors, microprocessors, real-time display and automatically record the temperature and humidity data collected , save it in the recorder in the non-volatile memory. Recording capacity from 4000 group -128 000 group, calculated per 30 minutes of recording time about a year to record temperature and humidity data, which is the traditional instrumentation can not do.
Recorder records with a variety of ways and any records set intervals, to ensure the instrument of environmental adaptation and the reliability of the recorder without any of the switches and buttons, all settings and off on all through the communication interface from the general computer run the application to set the soft panel.
Recorder can be torn off and the computer to work independently. When you need to read the data can be read by a computer communication interface, the data recorder.
◆ powerful data processing capability
ZDR Series intelligent temperature and humidity data logger configuration of multiple records for data analysis and processing software, standard Windows 95/98/2000 interface, can communicate with the data recorders, set the working status of intelligent recorder, read the intelligence data collected by the recorder . Its main function is, in Windows, the collected data can be a list, drawn curve, set the engineering units, an average, peak, and real-time display. TEXT format according to the output data can also get into EXCEL spreadsheets or specialized software for data processing, draw bar, pie, curve fitting and so on.
◆ Use
①. Using the communication cable included with recorder and general computer (PC586 above it) connected to the serial port.
②. Recorder on the computer running the application, set up the recorder records start time, record period, stop time, stop mode and other parameters.
③. Set the recorder after the completion of disengagement with the computer, the recorder placed in a test is required occasions.
④. Testing has been completed, then the recorder and the computer is connected, run the recorder application to record within the data downloaded to a computer data processing.
