Thermometers and data loggers COMMETER -200 to + 500° C

Thermometers and data loggers COMMETER -200 to + 500° C. Instruments are designed for direct measurement and datalogging of temperature into the internal non-volatile memory. Free PC program enables to transfer recorded data via RS232 serial link to the personal computer for consequent evaluation. Instrument is connected to the PC through included communication cable only for data trasfer from the memory. During connection with the PC no measurement and record is enabled. Advantages: * included traceable calibration certificate, * selection of Pt1000 sensor or Ni1000 sensor from instrument keyboard * dual line LCD display with special symbols * adjustable dual alarm with audio indication for each channel * memory of minimum and maximum values * function Hold - manual storing of actual values for later displaying COMMON TECHNICAL PARAMETERS Operating temperature range: -30 to + 65° C Temperature inputs - RTD: Pt1000-3850ppm/ ° C: -200 to + 500° C Ni1000-6180ppm/ ° C: -50 to + 250° C Accuracy of the input Pt1000 without probe: ± 0.3° C from -50 to + 100° C ± 0.3% from reading from + 100 to + 500° C ± 0.6% from reading from -200 to -50° C Accuracy of the input Ni1000 without probe: ± 0.2° C from -50 to + 100° C ± 0.2% from reading from + 100 to + 250° C Resolution: 0.1° C from -99.9 to + 500.0° C, otherwise 1° C Connector of the temperature probe: Cinch Power: battery 9V Battery life: 6 months typically Mechanical dimensions: 141 x 71 x 27mm Modes of logging: 1. manual logging - capacity of 1000 stored temperature sets 2. automatic noncyclic logging ( logging stops after filling the memory) - total capacity of 16000 values 3. automatic cyclic logging ( logging continues after filling the memory - oldest values are being replaced by newest) - total capacity approx. 15200 values ( 14400 values for D0211 model) Real time clock: year, leap year, month, day, hour, minute, second PC interface: serial RS232 Sampling interval in logging mode: 18 adjustable values from 10s to 24hours Warranty: two years.
