The PCE-HPT 1-ICA is a professional single-channel data logger designed for temperature measurement, recording and analysis in industrial, technical and laboratory applications. The instrument uses a Class A Pt100 sensor with a four-wire connection, a configuration particularly suitable for reducing the influence of lead resistance on the measurement result. Compared with conventional two-wire systems, four-wire technology provides more effective compensation for the resistance introduced by the connecting leads, supporting reliable and repeatable measurements even when longer sensor cables are required.

Its measuring range from -100 to +400 °C allows the data logger to be used for low-, medium- and high-temperature monitoring. Typical applications include climate chambers, test benches, heating and cooling systems, production machinery, mechanical components, laboratory equipment, technical furnaces and processes in which thermal stability affects product quality or manufacturing performance.

The Class A Pt100 sensor combines high measurement precision with a fast response time, making the PCE-HPT 1-ICA suitable for both individual checks and continuous observation of temperature trends. Its responsive measuring system helps identify fluctuations, thermal drift and sudden changes that may indicate process anomalies, incorrect settings, heat losses or non-uniform operating conditions.

The data logging function automatically stores the measured values in the internal memory. The sampling interval can be adjusted from 00:01 to 60:59, allowing the recording frequency to be matched to the duration and dynamics of the monitored process. A short interval is recommended when temperatures change rapidly or when heating and cooling phases must be analysed in greater detail. A longer interval can be selected for extended tests, stability checks and environmental monitoring, reducing the volume of recorded data while preserving a clear overview of the temperature trend.

An internal clock assigns a date and time to every stored measurement, improving traceability and allowing temperature changes to be correlated with specific production stages, machine start-ups, setting adjustments, maintenance operations or operating anomalies. The recorded data can be transferred to a computer and processed using the supplied software, which also enables real-time display of the measured temperature. Technicians can therefore monitor process development, compare different operating cycles and retain documented results for testing, quality control and process optimisation.

Correct sensor positioning is essential for obtaining reliable results. During contact measurements, stable thermal coupling should be ensured between the probe and the component being inspected. Areas influenced by external heat sources, air currents or non-representative surface conditions should be avoided. For immersion measurements, the insertion depth should remain consistent and sufficient time should be allowed for the reading to stabilise. During comparative tests, the sensor position, contact conditions and surrounding environment should remain as constant as possible, ensuring that recorded differences are caused by the monitored process rather than by variations in the measuring method.

The backlit display improves readability in poorly illuminated working areas, while the Data Hold function keeps the current value visible on the screen. The instrument also features automatic power-off, battery status indication and selectable °C or °F units. These functions support efficient use during maintenance work, system inspections and field measurement campaigns.

An ISO certificate is included with the instrument, supporting the documentation of its metrological performance and applications requiring enhanced measurement traceability. This makes the PCE-HPT 1-ICA particularly suitable for quality departments, laboratories, companies operating under internal inspection procedures and professionals who need to demonstrate the reliability of their measuring equipment.

By combining a Class A Pt100 sensor, four-wire measurement technology, internal data storage, adjustable sampling intervals and analysis software, the PCE-HPT 1-ICA provides a complete solution for accurate and documented temperature measurement. It helps technicians and engineers detect thermal instability, verify process settings and improve the monitoring of industrial operations.
