PT100 probe, 1/10 DIN accuracy, 2 m

The Pico SE012 PT100 Probe with 1/10 DIN accuracy and 2 m cable is designed for applications where higher temperature-measurement accuracy is required than a standard Class A or Class B PT100 probe can provide.

Pico Technology specifies the SE012 as a high-precision platinum resistance thermometer (PRT) with an accuracy of ±0.03 °C at 0 °C and a measurement range from −50 °C to +250 °C.

The probe is recommended for use with the Pico PT-104 High-Accuracy Temperature Data Logger, making it suitable for laboratory, research, calibration and engineering applications that require stable and repeatable temperature measurement.

High-Precision 1/10 DIN PT100 Measurement

The key advantage of the SE012 is its 1/10 DIN tolerance specification.

At 0 °C, Pico specifies:

• Accuracy: ±0.03 °C
• Accuracy class: 1/10 DIN

This is significantly tighter than Pico's standard Class A PT100 probes, which are typically specified at ±0.15 °C at 0 °C.

The higher accuracy makes the SE012 particularly useful for:

• Precision temperature logging
• Calibration-related measurements
• Laboratory testing
• Thermal characterization
• Environmental chamber validation
• Scientific experiments
• High-accuracy process monitoring

−50 °C to +250 °C Temperature Range

The SE012 supports a published measurement range of:

• Minimum temperature: −50 °C
• Maximum temperature: +250 °C

This range makes the probe suitable for both below-ambient and elevated-temperature measurements.

Typical applications include:

• Laboratory temperature monitoring
• Thermal chambers
• Liquid and air temperature measurements where probe construction is appropriate
• Electronics thermal testing
• Equipment temperature monitoring
• Industrial experiments
• Research and development
• Temperature reference measurements

Stainless-Steel Probe

The sensing probe is manufactured from stainless steel.

Pico specifies the probe dimensions as:

• Probe length: 150 mm
• Probe diameter: 4 mm

The slim 4 mm probe diameter makes it suitable for measurement points where a relatively narrow sensing element is required.

2 m PTFE Cable

The SE012 is supplied with a:

• 2 metre PTFE cable

PTFE cable insulation is suitable for the published operating temperature range of this probe and provides flexibility when the measurement point is positioned away from the data logger.

The 2 m lead is useful in:

• Environmental chamber testing
• Laboratory benches
• Process equipment
• Remote measurement points
• Test fixtures
• Temperature-monitoring installations

Four-Wire PT100 Construction

The SE012 uses a 4-wire connection.

Four-wire PRT measurement is preferred for high-accuracy temperature measurements because the measurement instrument can compensate for resistance in the connecting leads.

This is particularly important with precision PT100 sensors, where even small amounts of cable resistance can otherwise contribute to measurement error.

The four-wire design is therefore well matched to the high-accuracy capability of the Pico PT-104 data logger.

4-Pin Mini-DIN Connector

The SE012 is fitted with a:

• 4-pin mini-DIN connector

This connector allows direct connection to compatible Pico temperature data-logging equipment such as the PT-104.

The term “1/10 DIN” does not describe the connector. It refers to the probe's temperature-accuracy tolerance class.

Recommended for Pico PT-104

Pico Technology lists the SE012 as a recommended temperature sensor for the PT-104 High-Accuracy Temperature Data Logger.

The PT-104 supports high-resolution PT100 and PT1000 measurements, while the SE012 provides the precision PRT sensor needed to take advantage of high-accuracy temperature-logging applications.

This combination is suitable for:

• Precision temperature acquisition
• Multi-point PT100 measurements
• Research laboratories
• Calibration work
• Environmental testing
• Product qualification
• Long-duration temperature monitoring

Complete Measurement Accuracy

When using the SE012 with a data logger, overall system accuracy depends on both:

• Probe accuracy
• Data logger accuracy

The SE012 itself is specified at ±0.03 °C at 0 °C.

For high-accuracy applications, users should consider the combined uncertainty of the probe, logger, installation conditions and any applicable calibration data rather than treating the probe specification alone as the complete system accuracy.

No Handle Design

Pico specifies:

• Handle: No

The SE012 consists of the stainless-steel sensing probe connected directly to its PTFE cable rather than using a separate hand-held probe handle.

This configuration is suitable for fixed, semi-permanent and laboratory measurement installations.

Typical Applications

The Pico SE012 is suitable for:

• High-accuracy temperature measurement
• PT100 temperature logging
• Calibration laboratory measurements
• Scientific research
• Environmental chamber testing
• Electronics thermal characterization
• Product temperature validation
• Laboratory experiments
• Industrial temperature monitoring
• Process temperature measurements
• Equipment thermal studies
• Long-duration temperature recording
• Multi-channel PT-104 measurements
• Research and development
• Quality-control testing
