DNL920A wireless temperature and humidity collector-Fornitore globale

8th Floor, Building 2, East China Normal University Science and Technology Park, 1038 Jinshajiang Road, Shanghai, China

Instrument Introduction
DNL9The 20A wireless temperature collector is equipped with a built-in temperature and humidity sensor and four two-wire external interfaces, which can measure signals such as temperature, voltage, current, frequency, and pulse. The data can be stored in the built-in storage before being transmitted to the DataSuite for online monitoring. The collector can not only store data for data transmission, but also act as a node of the entire network, extending the distance of wireless data transmission.


Instrument characteristics
ØCan accurately measure up to 5 input signals ØReal time adjustment of sampling time interval and data transmission frequency to save battery power ØData can be viewed through the LCD display screen ØSupport expandable units when connecting external current or voltage sensors ØThere is an alarm display
