Frequently Asked Questions

Q: Can I use this probe in a cold storage room (-40°C)?
A: Yes! It operates down to -52°C, but avoid temps below -34°C to prevent seal damage.

Q: What’s the minimum target size for accurate readings?
A: Use a flat target ≥30.5mm (1.2in) or a shaft ≥152mm (6.0in) for reliable data.

Q: Does the “Multiple Approvals” suffix mean it’s explosion-proof?
A: It meets enhanced safety standards—check local regulations for specific certifications.
