Frequently Asked Questions
Can really carry this to a foundry and calibrate furnace thermocouples?
Yes. The dual-block design means you can validate both ambient-temperature reference sensors and high-temperature furnace probes in a single portable unit. Technicians appreciate not having to transport multiple baths or wait for lab turnaround.
What's the accuracy at 650°C?
±0.5°C at 650°C—remarkable for a portable instrument. NABL calibration ensures traceability. Industrial furnaces typically maintain ±5–10°C stability, so ±0.5°C measurement is more than sufficient to validate control thermocouple performance.
How long does it take to reach 650°C from ambient?
First heat-up from ambient to 650°C takes ~40–50 minutes. Subsequent temperature transitions are faster (20 minutes from setpoint to setpoint). Plan for 2–3 hours to validate all thermocouples on a typical furnace.
Is the handle heat-safe to touch at 650°C?
The exterior handle features thermal insulation; the block itself reaches 650°C but the handle stays <50°C. Always use caution, and avoid direct hand contact with the heated block when validating thermocouples at high temperatures.
What happens if I spill water on it?
IP54 sealing protects internal electronics from splashes, but direct water immersion isn't recommended. In a damp foundry environment, wipe-down with a dry cloth and store in a protective case between uses.
What is a dry block calibrator?
A dry block calibrator is a precision temperature calibration instrument that uses a heated metal block to verify the accuracy of thermocouples, RTDs, temperature sensors, and digital thermometers without using liquids.
What is a temperature calibrator used for?
A temperature calibrator is used to verify and calibrate temperature measuring instruments, ensuring accurate readings for industrial processes, laboratories, quality control, and maintenance applications.
Which temperature sensors can be calibrated?
This portable dry block calibrator is suitable for calibrating thermocouples, RTDs, PRTs, temperature probes, transmitters, and digital thermometers using interchangeable inserts.
Why choose a portable dry block calibrator over a liquid bath?
A portable dry block calibrator offers faster setup, clean operation, excellent portability, and minimal maintenance, making it ideal for field calibration and industrial maintenance.
Which industries use dry block calibrators?
Dry block calibrators are widely used in power plants, pharmaceutical manufacturing, foundries, heat treatment, aerospace, petrochemical, calibration laboratories, and process industries.
Does the calibrator support ISO/IEC 17025 calibration?
Yes. The calibrator supports traceable calibration workflows and is suitable for laboratories and industries following ISO/IEC 17025 quality requirements.
