Portable Dry Block Calibrator (650°C)
Indeecon portable high-temperature dry block calibrator up to 650°C. Handheld field-ready, NABL traceable. Perfect for on-site furnace calibration.
A dry block calibrator is a portable temperature measurement instrument used to calibrate thermocouples, RTDs, and temperature sensors across industrial ranges. Unlike liquid calibration baths, dry blocks use heated/cooled metal blocks for rapid, precise calibration from ambient to 1200°C, making them ideal for field work, process validation, and aerospace compliance (AMS2750G).

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.
