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, for example 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 the recording stops after filling the memory, or cyclic, when after filling the memory the oldest stored values ​​are overwritten with the new ones.

Measured values ​​are displayed on the display with backlight option and possibility to change the size of the display digits
 

Power supply

Multilogger can be operated with an AC adapter or with 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 allow logging and measurement during a power failure. 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 signaling can be acoustic (built-in acoustic alarm), optical, by sending an alert via e-mail 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

• Send an email when an alarm state starts or ends
• Use DATALINK - display current values ​​or download values ​​from memory to the COMET database on your PC. 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 applications to read the actual measured values ​​using the universal SNMPv1 and XML protocols
• Display the 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 doorbell, telephone dialer, etc.
• Output type: Open collector transistor
• Maximum switching current: 100 mA
• Maximum voltage at output: 24 V
• Auxiliary voltage at terminal: +5 V (only when mains supply is present)
• Users can receive alarms if values ​​go outside the set parameters. Alarms are indicated via an internal buzzer, 3 LEDs or email alerts via the Ethernet port.
