|
This instrument is a portable 31/2 digit., compact-size ddigital thermometer designed |
|
to use external K-type thermocouple as temperature sensor. Temperature |
|
|
indication follows National Bureau of Stards IEC584 temperature/voltage tables for K-type |
|
thermocouples. One K-type thermocouples is supplied with the thermometer. |
