Industrial Sensor
The DL-303 CR records carbon monoxide, carbon dioxide, temperature, humidity and dew point together, with date and time stamps on every record. Readings are shown simultaneously on a 2.8-inch touch screen, and a single relay output can drive an alarm device or an indoor air quality (IAQ) control device.Data can be read over RS-485 using DCON or Modbus RTU, or over Ethernet using Modbus TCP or MQTT. The unit can be powered from PoE (IEEE 802.3af, Class 1) or from a +12 ~ +48 VDC terminal block, which simplifies installation where a network cable is already present. Configuration is available through the touch screen or the built-in web server.Logged data can be downloaded and exported to CSV for analysis. Free Windows utility software, iOS and Android apps are included, and multilingual on-screen messages can be shown to prompt operators. The device is listed with CE, UKCA, FCC, RoHS and WEEE certification.ApplicationsTransportation of food or pharmaceuticalsFood and beverage industry (HACCP)Blood stations and pharmaciesBuilding and energy managementWarehouse managementMuseums, archives and galleries
