Comet M1321 – Multilogger – Universal 4 Channel Thermometer Hygrometer with 2 MiniDIN and 2 Terminals

• Up to 16 values can be calculated from 4 connected sensors/signals.
• This is the sum of measured and calculated values. E.g. dew point temperature, absolute humidity, specific enthalpy, inter-channel conversion (difference between two connected temperature sensors)

The Multilogger has been designed for measuring and recording physical and electric quantities with an adjustable logging interval from 1 second to 24 hours. The device is equipped with 4 inputs (connectors) for external probes or signals. Moreover, some versions also include an internal atmospheric pressure and/or CO2 concentration sensor. The production line consists of several models with various combinations of the input ranges of the measured quantities. The Multilogger can be used either as a stationary or portable device.

Communication

• To communicate with a PC and other systems, the device is equipped with a USB port (located on the side of the device), RS232, and Ethernet.
• The multilogger comes with a USB and Ethernet interface. For WiFi communication, the multilogger can be connected to a TP-LINK WiFi router.

ETHERNET interface allows you to

• Send an e-mail if the Multilogger is in an alarm state. The Multilogger can also be connected to the Local Area Network and comes with a web browser. COMET also supplies a SQL Database that allows the customer to store, download and view historical data in detail for full analysis.
• In case of connection failure, use DATALINK for upload values to COMET Database
• Third-party applications to read the actual measured values using universal protocols SNMPv1 and XML

Output Alarm Out

• Output can be used for controlling other devices when an alarm is launched, such as an external buzzer, telephone dialer, etc.
• Users can receive alarms if the values go outside the parameters set. Alarms are indicated through an internal buzzer, 3 LEDs, or email alerts via Ethernet port.

Power Supply

• Power supply is provided from the 5V DC AC adapter and operation of the device (except Ethernet interface) is backed up by replaceable batteries.
• The device can be used permanently installed or as a portable device with the option to charge batteries directly using the AC adapter or using standard alkaline batteries size AA.

Software

• Comet Database
• Complex solution for data acquisition, analyzing, and sending SMS or email alarms. Easy to use and high flexible Database software for all Comet Data Loggers and Transmitters.
• Comet Vision
• Free configuration software for Comet Multiloggers.
