Thermometers and data loggers COMMETER -200 to + 1700° C for thermocouples K, J, S

Thermometers and data loggers COMMETER -200 to + 1700° C for thermocouples K, J, S 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 thermocouple type from instrument keyboard * automatic compensation of cold junction temperature * 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: -10 to + 60° C Connector for probe connection: subminiature connector for thermocouples Accuracy without probes - thermocouples K ( NiCr-Ni) : ± ( 0.4° C + 0.1% from reading) from -200 to + 1300° C Accuracy without probes - thermocouples J ( Fe-Co) : ± ( 0.4° C + 0.1% from reading) from -200 to + 750° C Accuracy without probes - thermocouples S ( PtRh-Pt) : ± ( 0.85° C + 0.1% from reading) from -50 to + 1700° C Resolution: J, K thermocouples: 0.1° C from -99.9 to + 999.9° C, otherwise 1° C S thermocouples: 0.4° C from -50.0 to + 999.9° C, otherwise 1° C Power: 9V battery Battery life: typically 2 months Dimensions without probes: 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 single channel thermometer D0311) 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 24hour Warranty: two years
