Type-K Thermocouple for Asphalt Temperature Measurement Myzox AST-10 Malaysia
Type-K Thermocouple for Asphalt Temperature Measurement Myzox AST-10 Malaysia
When contractors need to measure hot asphalt temperature during road construction, selecting the correct thermometer is only part of the decision. The type of temperature sensor and probe is equally important.
The Myzox AST-10 Digital Asphalt Thermometer uses Type-K thermocouple probes and is designed for pavement temperature control.
For penetration measurement of asphalt, the AST-10 can be paired with the Myzox SE-IN 200 mm needle probe, providing a practical solution for road contractors, civil engineers and QA/QC teams in Malaysia.
What Is a Type-K Thermocouple?
A thermocouple is a temperature sensor that uses two dissimilar metal conductors to produce a small electrical signal related to temperature.
A compatible digital thermometer interprets this signal and displays the temperature numerically.
Type-K is a widely used thermocouple type for many contact temperature measurement applications.
The Myzox AST-10 is designed to work with Type-K thermocouple probes.
Why Use a Thermocouple for Asphalt?
Asphalt temperature measurement can involve relatively high temperatures compared with many ordinary environmental measurements.
A suitable thermocouple system offers several advantages:
Direct contact measurement
Different probe designs
Wide temperature capability
Portable field use
Penetration measurement
Surface contact measurement with an appropriate probe
For asphalt applications, the important point is to select a probe designed for the required measurement method and temperature range.
Myzox AST-10 Type-K Measurement Range
The AST-10 main instrument supports Type-K thermocouple measurements from:
-200°C to +1,370°C
However, this is the range of the main instrument.
The actual usable temperature range depends on the connected probe.
This distinction is important when selecting temperature equipment.
SE-IN Probe for Asphalt Measurement
For asphalt penetration measurement, Myzox offers the SE-IN Needle Probe.
Its specifications include:
Probe length: 200 mm
Temperature range: -50°C to +650°C
Probe type: Penetration needle probe
Myzox identifies the SE-IN as suitable for asphalt measurement.
This makes the AST-10 and SE-IN combination particularly relevant to road construction.
Why Does Probe Range Matter?
A common mistake is to look only at the thermometer's maximum measurement range.
For example:
AST-10 main instrument: up to +1,370°C with Type-K thermocouple measurement.
But:
SE-IN probe: up to +650°C.
The measurement system must always be used within the limits of the connected probe.
A high-range thermometer does not increase the safe temperature capability of a lower-range probe.
Why Does Probe Design Matter?
Different temperature applications require different probe designs.
For example:
Air measurement
Liquid measurement
Surface measurement
Penetration measurement
For asphalt, a needle-type penetration probe allows the sensor to make direct contact with material below the immediate exposed surface.
This is why the SE-IN 200 mm needle probe is useful for asphalt work.
Type-K Penetration Measurement vs Infrared Measurement
A Type-K penetration thermometer and an infrared thermometer do not measure asphalt in the same way.
Infrared Thermometer
Typically measures:
Exposed surface temperature
Advantages can include:
Fast readings
Non-contact operation
Convenient surface scanning
AST-10 with Type-K SE-IN Probe
Measures by:
Direct contact and penetration
This allows temperature to be checked within the asphalt material.
The appropriate method depends on the project's measurement requirement.
Where Can Type-K Asphalt Measurements Be Taken?
Depending on the approved QA/QC procedure, the AST-10 may be used during:
Asphalt delivery
Road paving
Behind-paver inspection
Before compaction
During rolling
Asphalt resurfacing
Highway rehabilitation
Pothole repair
Car park paving
Industrial road construction
The measurement location and frequency should follow the applicable project requirements.
Why Use a 200 mm Probe?
The SE-IN has a probe length of approximately 200 mm.
This provides useful reach for penetration measurements and allows contact with asphalt beneath the immediate exposed surface.
The actual insertion depth should be determined according to the project's measurement procedure.
Can the AST-10 Use a Surface Probe?
Yes.
Myzox offers the optional SE-SU Surface Probe.
Its specified measurement range is:
-20°C to +400°C
This provides contact surface temperature measurement where required.
By changing the Type-K probe, one AST-10 main instrument can support different measurement applications.
What Is the SE-WI Wire Probe?
The AST-10 can also support the SE-WI Wire Probe.
Its specified measurement range is:
-30°C to +200°C
The correct probe should always be selected according to the intended measurement application.
For asphalt penetration, the SE-IN remains the relevant option.
Data Hold with Type-K Measurements
The AST-10 provides a Data Hold function.
Once a stable temperature has been obtained, the user can retain the displayed value.
This can be useful when taking measurements around active paving equipment and recording results afterward.
MAX and MIN Functions
Additional functions include:
MAX measurement
MIN measurement
Relative measurement mode
These provide extra flexibility when monitoring temperature changes in field applications.
How to Choose a Type-K Thermometer for Asphalt
Before buying an asphalt thermometer, consider several factors.
Temperature Range
Check both the main instrument range and probe range.
Probe Type
For penetration measurement, select a suitable needle or penetration probe.
Probe Length
Make sure the probe provides appropriate reach for the intended measurement.
Field Functions
Functions such as Data Hold and MAX/MIN can improve practical usability.
Replacement or Alternative Probes
A thermometer that accepts interchangeable probes can support more than one type of contact temperature measurement.
Common Mistake: Buying the Thermometer Without Checking the Probe
The thermometer and probe work as a measurement system.
A buyer should therefore not ask only:
“What is the thermometer range?”
Also ask:
“What is the probe range?”
and:
“Is the probe suitable for asphalt penetration?”
For the Myzox AST-10, the SE-IN provides the penetration probe specifically relevant to asphalt applications.
FAQ: Is Myzox AST-10 a Type-K Thermometer?
Yes.
The AST-10 supports Type-K thermocouple measurement.
FAQ: Which Type-K Probe Is Suitable for Asphalt?
The Myzox SE-IN Needle Probe is suitable for asphalt penetration measurement.
It is approximately 200 mm long and has a specified range of -50°C to +650°C.
FAQ: Can I Use Any Type-K Probe?
A compatible probe may electrically connect to a Type-K thermometer, but users must still consider probe design, connector compatibility, temperature range and application suitability.
For Myzox AST-10 asphalt applications, the SE-IN is the specified relevant probe.
FAQ: Is Type-K Better Than Infrared for Asphalt?
They serve different measurement purposes.
Type-K penetration measurement provides direct contact temperature within the material.
Infrared measurement generally provides non-contact surface temperature.
The project requirement should determine which method is appropriate.
Type-K Asphalt Thermometer for Malaysian Road Contractors
Selecting an asphalt thermometer is not simply about choosing the instrument with the highest temperature number.
