Frequently Asked Questions
Why is the vertical design important?
Vertical chambers minimize floor footprint while maximizing usable volume—critical in manufacturing facilities where space is premium. A 137L vertical chamber occupies roughly 60 cm × 40 cm floor space versus 100 cm × 80 cm for an equivalent horizontal chamber.
How many sensors can I calibrate simultaneously?
With dual shelves, you can typically calibrate 20–40 sensors depending on probe size. Larger sensor clusters (e.g., automotive harnesses with 5–10 thermocouples) may reduce the count. Consult Indeecon for your specific loading scenario.
What's the typical cycle time for a multi-point calibration?
A standard 5-point calibration (-20, 0, 25, 50, 80°C) with 20-minute stabilization at each setpoint takes approximately 2.5–3 hours. With parallel loading, you can validate 20–30 sensors in a single shift.
Is this suitable for OEM automotive supply chain qualification?
Yes. Indeecon designs this chamber to meet automotive supplier requirements (IATF 16949, APQP protocols). NABL certification and integrated data logging provide the traceability required for OEM quality gates.
Can I control this remotely for shift monitoring?
Yes. The Ethernet interface allows remote temperature monitoring via secure web interface or SCADA integration. Alarm notifications can be sent to maintenance staff via email or SMS.
