Class A PT100 Temperature Measurement

The SE015 uses a PT100 platinum resistance sensing element with a manufacturer-specified Class A accuracy of:

• ±0.15 °C at 0 °C

Class A performance makes the probe suitable for engineering and laboratory applications where reliable and repeatable temperature measurement is required.

Typical uses can include:

• Laboratory temperature testing
• Engineering experiments
• Product thermal evaluation
• Equipment testing
• Research and development
• Quality-control measurements
• Temperature data logging
• Suitable insertion measurement points in test assemblies

−75 °C to +250 °C Measurement Range

Pico specifies an operating measurement range of:

• Minimum temperature: −75 °C
• Maximum temperature: +250 °C

This broad range supports both sub-zero and elevated-temperature measurement applications.

The complete measurement setup should remain within the probe's specified range and be suitable for the physical construction of the sensor, cable and handle.

Designed Specifically for Insertion Measurements

The SE015 is specifically described by Pico as an insertion probe.

Its stainless-steel sensing stem can be inserted into suitable measurement locations where direct contact with the test object is required.

Possible engineering uses include:

• Temperature measurement inside suitable test fixtures
• Thermal characterization of test objects
• Product-development experiments
• Laboratory insertion measurements
• Equipment temperature validation

The probe should only be inserted where its dimensions and physical construction are suitable for the application.

Important Difference from an Immersion Probe

The SE015 should not automatically be described as an immersion probe.

Pico sells a separate model, SE014, specifically identified as a PT100 immersion probe.

For this reason, the SE015 product page should focus on insertion applications, rather than broadly claiming suitability for liquid immersion unless Pico explicitly approves the intended installation.

This distinction improves both technical accuracy and product selection.

120 mm Stainless-Steel Probe

The SE015 sensing stem is specified as:

• Length: 120 mm
• Diameter: 3.3 mm
• Material: Stainless steel

The relatively narrow probe diameter makes it suitable for insertion into compatible measurement locations where a slim temperature probe is required.

The 120 mm length provides useful insertion reach for laboratory and engineering applications.

1 m Coiled PVC Cable

Pico specifies the SE015 with:

• Cable length: 1 metre
• Cable form: Coiled
• Cable material: PVC

The coiled cable provides flexibility between the measurement point and the connected data logger while helping reduce loose cable around a test setup when the full extension is not needed.

This can be useful on:

• Laboratory benches
• Engineering test stations
• Product-development setups
• Research experiments
• Temperature-logging systems

Four-Wire PT100 Construction

The SE015 uses a 4-wire PT100 connection.

Four-wire resistance measurement allows a compatible temperature instrument to compensate for resistance in the probe leads.

This is important because PT100 temperature measurement is based on small changes in electrical resistance. Lead resistance can otherwise introduce additional measurement error.

The four-wire configuration therefore supports more accurate PRT measurement when used with compatible instrumentation.

4-Pin Mini-DIN Connector

The probe is fitted with a:

• 4-pin mini-DIN connector

This enables direct connection to compatible Pico PRT measurement hardware.

The connector should be described precisely as 4-pin mini-DIN. DIN accuracy classifications and mini-DIN connector types are separate specifications.

For the SE015:

• Accuracy classification: Class A
• Physical connector: 4-pin mini-DIN

Integrated Probe Handle

Pico specifies:

• Handle: Yes

The integrated handle makes the SE015 convenient for insertion measurements where the probe may need to be positioned, removed and repositioned manually.

This distinguishes it from fixed probe styles supplied without a handle.

Recommended for Pico PT-104

Pico lists the SE015 as a recommended accessory for the PT-104 High-Accuracy Temperature Data Logger.

The PT-104 provides four PRT measurement channels and supports standard PT100 and PT1000 sensors.

Using the SE015 with the PT-104 creates a suitable measurement system for:

• Insertion temperature logging
• Engineering development
• Laboratory experiments
• Product testing
• Research applications
• Multi-point thermal measurement
• Long-duration temperature recording

Multiple SE015 probes can be connected to available PT-104 channels for simultaneous measurements.

Probe Accuracy and Overall System Accuracy

The published ±0.15 °C at 0 °C specification applies to the SE015 probe.

The total accuracy of a complete temperature-measurement system also depends on:

• Data logger accuracy
• Probe tolerance at the measured temperature
• Probe insertion depth
• Thermal contact
• Measurement environment
• Calibration status
• Heat transfer between the probe and test object

For precision measurements, the complete measurement chain should therefore be considered rather than using the probe's Class A specification alone.

Typical Applications

The Pico SE015 is suitable for:

• PT100 insertion temperature measurement
• Laboratory testing
• Engineering development
• Product thermal testing
• Temperature data logging
• Research experiments
• Equipment temperature validation
• Quality-control measurements
• Prototype testing
• Multi-point temperature monitoring
• Educational laboratory experiments
• PT-104 temperature-logging systems
