Features of This Product
This product is a handy-type thermometer that can measure a temperature and
make a record of it. It has a “collector function” to record the measured tempera-
tures and measurement conditions under the specified tag, and a “logging func-
tion” to automatically measure and record temperatures at given intervals.
The TM20 can simultaneously measure temperatures of channels A and B as well
as being able to measure a potential difference. The following describes the col-
lector and logging functions.
■
Collector function
The collector function is used when the measured temperature and measurement conditions
are recorded under the specified “tag”.
In the “tag”, the tag name (i.e. “what”), date and time (i.e. “when”), operator name (i.e. “who”),
and alarm (i.e. “judgment on the measured data”) are recorded as the measurement condi-
tions, in addition to the measured temperature.

It is possible to use maximum 50 tags, and in these 50 tags, a total of 5,000 pieces of tempera-
ture measurement data can be recorded. However, the more the data is saved with the logging
function, the less number of measurements can be made with the collector function.
[TIP]
At the two-channel simultaneous measurement, 2 data can be recorded in every measurement. If no
data is recorded at the two-channel simultaneous measurement, 2,500 measurements can be recorded.
Set up the following tag items in advance to use the collector function.
• Tag name
• Input channel
• Alarm
• Operator name
