2 Introduction
2.1 General information
This operating manual supplements product-specific data sheets and applies generally for JUMO ther-
mometers used for contact-based temperature measurement.
NOTE!
Additional useful literature is referenced in chapter 12 "Further information and downloads", Page 45. If
you have any doubts, follow the specifications in the product-specific operating manuals or data sheets.
WARNING!
Risk of personal injury or damage to property!
Improperly performed work will result in personal injury or damage to property.
As a basic principle, installation and startup work for JUMO thermometers may only be performed
by qualified and authorized personnel who strictly follow this manual, the relevant standards and le-
gal regulations, the safety provisions, and the application-specific certificates.
2.2 Identifying the device version
In addition to clearly defined outer geometries, color coding for the connection lines, and resistance mea-
surements between the connection poles, thermometers are also identified by their nameplates and la-
beling.
Labeling example
NOTE!
The fabrication number on the nameplate is the most important specification when communicating with
JUMO.
Thermocouple or RTD temperature probe?
The following table serves as a general guide for comparing RTD temperature probes and thermocou-
ples. The particular features in individual cases are determined by the specific thermometer design.
(1) Company identifier
(2) Probe type
(3) Sensing element
(4) Part number, 8-digit
(5) Fabrication number, max. 19-digit
