- Research and development
- Laboratories
- Technological processes
Advantages of data logger:
- included traceable calibration certificate from the manufacturer - Comet
- fast data transfer to the PC (full memory for approximately 30s)
- variability of connection to the computer - USB, RS232, Ethernet, GSM modem
- permanent connection to the PC enabled, data is possible to download even during logging
- large data memory 32000 values
- large dual line display with special symbols, switchable
- optional display of minimum and maximum measured values (reset of min/max memory from PC or by magnet)
- dual level alarm is enabled for each channel, alarm is indicated by blinking of the value on the LCD display
- two alarm modes are enabled: instant or with memory (detected alarm is indicated permanently till alarm memory is cleared)
- robust watertight case
- easy installation, locking enabled
- low power consumption from battery, battery life up to 6 years
- indication of remaining battery life, easy replacement of the battery
- logging start/stop is enabled: at certain time and date programmed from computer, by external binary signal or by delivered magnet
- also special logging mode is enabled, when logging runs only, if some of measured values are out of adjusted alarm limits
- input signal is recalculated and displayed in real measured physical units by means of the PC software
- each logger is possible to describe with text of maximum 32 characters
- each channel is possible to describe with text of maximum 16 characters
- password protection is enabled to prevent unauthorized manipulation with logger

Accessories
Traceable calibration certificate from the manufacturer, instruction manual.
Calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
Example of calibration certificate.
No other accessory is included. For basic use it is necessary to order at minimum a COM adapter or USB adapter for communication with computer, optionally a start/stop magnet, if needed to control logging the other way than directly from computer or by external binary signal. Also connector for input signals connection is necessary to order.
Anytime it is possible to download free basic Windows program for data logger. Program enables to control all logger functions and viewing and printing of record in numerical and simple graphic format. It is possible to export recorded values to dbf or txt formats for further analysis.
| OPTIONAL ACCESSORIES | ||
|---|---|---|
