Portable Temperature / RH Data Loggers with OLED Display

image

New Portable DLT-10 (11) Series Data Loggers are miniature electronic devices with soldered battery, OLED display and USB-interface. Data Logger measures and records temperature and humidity readings in the internal memory.

Loggers are used to measure temperature and relative humidity during environmental monitoring in growing rooms, storage rooms and transportation of mushrooms and compost.
Temperature and humidity sensors are located inside the logger ecnlosure. The design of the logger allows you to connect up to two external temperature probes via USB-A connector. Humidity is measured by the original Swiss sensor.

The user can easily set up the data logger and download the saved data by plugging the device into computer’s USB port and running the easy-to-use LoggerSoft Software. The data saved in the logger’s memory is transferred to a computer in CSV or PDF formats.

Functions

  • Air/compost/substrate temperature and air relative humidity measurement
  • Data logging in a user-defined mode
  • Alarm logging
  • Data logger plugs directly into computer’s USB for easy setup and data download 
  • Compatible with standard Windows applications
  • Displaying modes, alarms and current sensor readings on the high-contrast OLED display
  • Downloading data reports with graph in PDF or CSV formats without pre-installed software
  • Flexible user configuration mode using special Loggersoft software

Design

Data logger is made from polycarbonate case with a standard USB connector, high-contrast OLED display and two control buttons. 
The lithium battery is soldered in the logger for harsh environments. 

Six icons on the display show:

  • Alarm status during logging
  • Data logger status (logging process/logger waiting to start/logging stopped)
  • Alarm signaling
  • Battery charge
  • Measured temperature and RH readings

 

Connection to PC

The logger is possible to connect to PC in one of two modes:

In the FLESH-Drive  mode data logger forms PDF or CSV report available for dowload to PC. To do this, connect the data logger to the PC USB port. The average time of report generation is 30 seconds.

In the COM-port mode the user can change data logger settings and read the stored data using LoggerSoft Software. For this purpose, press OK button and within 5 seconds connect logger to the PC USB port.
