Features

Up to 4 physical inputs - 2x MiniDin + 2x Thermocouple

• Pt1000 temperature probes with built-in configuration memory (xxx/M series)
• Temperature/relative humidity probes with digital output - DigiS/M, DigiL/M, DIGIH/M
• The probes are interchangeable without calibration to a specific device and regardless of the cable length. The cable length can be 1, 2, 5, 10, 15 meters.
• Thermocouple probe K, J, S, B, T, N
• Direct input of bipolar voltages with range up to -60 to +140 mV
• Sensors with voltage output (range -60 to +140 mV; accuracy ±100 µV or -18 to +18 mV; accuracy ±20 µV)
  
  
  
  
  
  
  
  
  
  

Evaluation of up to 16 variables

Up to 16 variables can be calculated from the four connected probes/sensors. This is the sum of the measured and calculated values. The calculated values ​​can be an additional expression of humidity: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. It can also be the result of conversions between channels, e.g. the difference of two connected temperature probes.

The measured values ​​are stored in the internal non-volatile memory. The memory capacity is up to 1 million values. The recording mode can be set as non-cyclic, when recording stops after filling the memory, or cyclic, when after filling the memory the oldest stored values ​​are overwritten with the new ones.

The measured values ​​are displayed on the display with backlight option and the ability to change the size of the display digits.





Power supply

Multilogger can be operated from an AC adapter or from rechargeable batteries with charging capacity. The batteries are always part of the device (you can also use standard AA alkaline batteries). The batteries power the device for several months.

While using the AC adapter, the batteries provide backup operations and enable recording and measurement during a power outage. Thanks to the Ethernet output, the device reports the failure via an e-mail message.





Alarm limits and alarm indication


It is possible to set two independent alarm limits for each channel (i.e. measured or calculated value).

Alarm signalling can be acoustic (built-in buzzer), optical, by sending an alert by email or an alarm output. The alarm output is for connecting an external visual or audio alarm.









Communication interfaces

• Multilogger is always equipped with a USB connector for communication, data analysis and also for charging the rechargeable batteries.
• Multilogger - Alarm limits
  
  
• sends an email when an alarm state begins or ends
• uses DATALINK: displays current values ​​or downloads values ​​from memory to the COMET database on your PC. The COMET Database software contains many useful tools for data analysis: graphs, tables, statistics, etc.
• Simple wireless communication with TP-LINK Wi-Fi router
• Third-party apps to read actual measured values ​​using universal SNMPv1 and XML protocols
• View current measured values ​​using your web browser
  
  
  
  
  
  
  

ALARM OUT output

• The output can be used to control other devices when the alarm is triggered, such as an external buzzer, telephone dialer, etc.
• Output type: Open collector transistor
• Maximum switching current: 100 mA
• Maximum switching current: 100 mA Output voltage: 24 Vuxiliary voltage at terminal: +5 V (only when mains power is present)
• Users can receive alarms if values ​​go outside the set parameters. Alarms are indicated by an internal buzzer, 3 LEDs, or email alerts via the Ethernet port.
