Platinum Resistance Thermometer Solutions for Laboratory Temperature Measurement
Our curated collection of resistance thermometers is suited to laboratories that need dependable thermal sensing for monitored experiments, sample handling, and instrument-connected workflows.
- Stable platinum sensor performance: Platinum resistance thermometer probes use temperature-dependent electrical resistance to deliver accurate and repeatable readings, making them well suited to controlled laboratory measurement.
- Application-led probe selection: The visible range is centred on Pt 1000 probe formats from Xylem, supporting users who need compact sensors, cable-connected designs, and consistent response in bench or instrument setups.
- Commercial relevance across technical sectors: These instruments also align with Life Science and Diagnostics and broader Test and Measurement workflows where accurate thermal data influences compliance, method repeatability, and procurement decisions.
How to Choose the Right Resistance Thermometers
Selecting the correct resistance thermometers for your facility requires evaluating several technical parameters:
- Sensor type and resolution: Confirm whether your instrument requires Pt100 or Pt1000 sensing. Pt1000 sensors provide a steeper characteristic curve and reduce lead-related error, which can be useful in two-wire configurations and cable-connected laboratory setups.
- Probe construction and fit: Assess cable length, probe diameter, insertion depth, and connector style so the sensor suits your vessel, chamber, or instrument geometry.
- Calibration and traceability: Review whether your process needs traceable calibration, comparison against a reference standard, or defined uncertainty for regulated laboratory work.
Complete Temperature Monitoring and Control Workflows
Versatile equipment is essential for comprehensive facility management. To further optimise your workspace, we recommend exploring these supporting links:
- Temperature Sensor: Extend your temperature monitoring options where alternative sensing formats or broader installation requirements are needed alongside resistance thermometers.
- Temperature Regulators: Pair sensing hardware with active control equipment when laboratory processes require monitoring and precise thermal adjustment in the same workflow.

Frequently Asked Questions
What is a platinum resistance thermometer?
A platinum resistance thermometer is a temperature sensor that measures temperature by tracking the change in electrical resistance of a platinum element, commonly used where stable and repeatable measurement is required.
How does a resistance thermometer work?
It works by measuring how the sensor’s electrical resistance changes with temperature. The measured resistance value is then converted into a temperature reading using the defined RTD characteristic curve.
Can John Morris Group support bulk orders or calibration-related requirements?
Yes. John Morris Group can assist with application-driven selection, quantity enquiries, and temperature measurement workflows where calibration suitability, sensor format, and system compatibility are part of the buying decision.
