DT1312 K-Type Digital Thermometer with Dual Sensors is designed for measuring and comparing temperatures at two different points using compatible K-type thermocouple probes. Its dual-channel functionality makes it useful for technicians, maintenance professionals, laboratories, HVAC applications and industrial temperature monitoring.
With separate T1 and T2 readings, users can monitor two temperature points and calculate the temperature difference between them using the T1–T2 function. Before purchasing, check the thermometer’s specifications, compatible probe types, measurement accuracy and the temperature limits of the supplied accessories.

Key Features of the DT1312 Digital Thermometer Dual Channel
1. Dual-Channel Temperature Measurement
The DT1312 supports two compatible K-type thermocouple inputs, allowing users to monitor two temperature points with one instrument. This can be useful when comparing temperatures across equipment, components, airflows or different areas of a process.
2. T1, T2 and Differential Temperature Readings
The thermometer’s dual-channel functionality allows users to compare the T1 and T2 readings. The T1–T2 function helps determine the temperature difference between the two measurement points.
This feature can support HVAC diagnostics, temperature comparisons and equipment troubleshooting.
3. K-Type Thermocouple Compatibility
The DT1312 is designed for K-type thermocouple measurement. Before connecting a probe, confirm its connector compatibility, temperature rating and suitability for the material or environment being measured.
The meter’s maximum measurement range does not automatically mean that every compatible probe can safely measure up to that temperature.
4. Temperature Unit Selection
Temperature readings can be displayed in the units supported by the exact instrument version. Check the manufacturer’s documentation to confirm the available unit options and operating procedure.
5. Practical Measurement Functions
Depending on the confirmed specification of your DT1312 version, available functions may include data hold and maximum/minimum temperature readings. These functions can help users record or compare measurements during inspections and troubleshooting.
Confirm the exact functions against the product manual before purchase.

Applications of the DT1312 K-Type Thermometer
The DT1312 may be suitable for applications that require two-point temperature measurement, provided the instrument and probes meet the relevant measurement requirements.
- HVAC and refrigeration: Compare temperatures at different points in heating, ventilation and air-conditioning systems.
- Industrial maintenance: Investigate temperature differences across equipment and components.
- Laboratory testing: Monitor and compare temperatures during suitable experiments and testing procedures.
- Equipment troubleshooting: Identify temperature variations that may require further inspection.
- Process monitoring: Compare temperature readings at two locations during routine checks.
Always select probes appropriate for the target temperature, surface, substance and working environment.
How to Use the DT1312 Dual-Channel Thermometer
Follow the manufacturer’s instructions for the exact instrument version. The general measurement workflow is:
- Check the thermometer, connectors and probes for visible damage.
- Confirm that the probes are compatible with the DT1312 and suitable for the expected temperature.
- Connect the probes to the appropriate T1 and T2 inputs.
- Switch on the instrument and select the required temperature unit, if supported.
- Position each probe correctly and allow the readings to stabilize according to the probe’s response characteristics.
- Read the individual T1 and T2 temperatures.
- Use the T1–T2 function, if available, to check the temperature difference.
- Record the readings and follow the manufacturer’s guidance for disconnecting and storing the probes.
Do not exceed the temperature rating of either the probe or its insulation. Follow the instrument manual for safe operation and measurement limitations.
