4 channels Simultaneous temperature recording
-200 to 1370°C Instrument measurement range
16,000 Stored records per channel
0.1°C / °F Resolution in the applicable range
Built for multi-point measurements
Follow the temperature at every test point
Use four thermocouple inputs to compare temperature conditions across a test setup. Record changes over time and review your measurements with the appropriate PC connection and software.
Internal data logging
Store up to 16,000 records per channel. Configure the recording interval to suit your observation period.
Practical everyday controls
Use HOLD and MAX / MIN functions to examine readings. Select Celsius or Fahrenheit for your reporting needs.
Application ideas
One logger, multiple temperature perspectives
Select the right Type K probes for the temperature range, surface or medium you need to measure.
HVAC & maintenance
Compare temperature points around air-handling equipment or thermal systems using suitable air and contact probes.
Laboratory & development
Observe heating and cooling at multiple locations during experiments, prototype evaluation and repeatable bench tests.
Production & process checks
Record temperature changes during equipment checks and process trials. Match probe ratings to the actual test conditions.

Frequently asked questions
Can the DTM-319 record four temperatures at once?
Yes. The DTM-319 accepts four Type K thermocouples and can display and record four measurement points simultaneously.
Does the DTM-319 support Type J, E or T probes?
This DTM-319 page covers the Type K model. If you need other thermocouple types, ask TECPEL to recommend a suitable model, such as the DTM-319A.
Does the included probe cover the full -200 to 1370°C range?
The stated range is the instrument range. Each probe has its own temperature limit. Choose a probe rated for your measurement temperature, medium and contact method.
How does the DTM-319 connect to a computer?
The instrument uses an RS-232 interface. USB connection requires the appropriate cable or adapter and driver. Confirm the supplied cable and software compatibility with TECPEL when ordering.
How much temperature data can it store?
The published storage capacity is 16,000 records per channel. Select a recording interval suitable for the length of your test and the speed of the temperature changes.
