Specification :

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
