Technical parameters: Temperature range: -30 ℃ ~ 70 ℃ Accuracy:. ± 0.2 ℃ Temperature resolution:. 0.1 ℃ temperature probe cable length:. 2m (standard) Humidity range: 0 to 100% humidity accuracy: ± 3% humidity resolution: 0.1% moisture level probe cable length: 1.5m (standard) recording capacity: 6 Channel> 80000 logger interval: 1 minute to 24 hours can be adjusted, timing or recording data Stop Power supply: 6 AA batteries (one hour intervals can be used for two months or so) to export the data:. USB interface for easy data suggested that the communication line 2 meters (standard) functions and features: This machine small volume , the software is simple to operate, reliable performance, recording intervals can be set from 1 minute to 24 hours upon request. . Whole track record of measured ambient temperature and humidity data, records a long time, with power and automatic data storage protection. Small machine power, use the built-in battery. Powerful software, data viewing convenience, you can always export the data logger to the computer, and can be stored as EXCEL spreadsheet file, generate data curves for other analysis software for further data processing. Single station logger can access up to six-channel temperature probe, probe to measure air, water or soil temperature, humidity distribution. The record can be torn off the computer to work independently when required to view the current environment within the data logger can be read by the computer via the communication interface. . A logger can measure temperature and soil moisture at multiple points. Scope: Widely used in soil temperature agriculture, forestry, geology, humidity measurement and research. Note: JL-01 standard products for the three-way and 3-way temperature and humidity, the product can be derived from unconventional customized products: For example: 6-way and 3-way temperature and humidity - a total of nine channels (6 temperature and humidity of the number 3 reducing the need to follow) 6-way humidity - a total of six channels free with humidity and temperature - a total of sixteen channels
