Product Specs

Magnetized probes, suitable for long term contact pressure. The 88401 uses PFA insulated lead wire and is rated to a max. surface temperature of 250°C (480°F). The 88402 uses "GG" fiberglass insulated lead wire and is rated to a max. service temperature of 400°C (750°F). Both sensors are supplied with an SMPW connector and TAS adaptor. K Calibration uses CHROMEGA™-ALOMEGA™ metals. E Calibration uses CHROMEGA™- Constantan metals.

Rated 5 out of 5 by from Amazing Product This product is a must have for any process engineer in the plastics injection molding field. I have purchased one of these magnetic thermocouples for all 3 companies that I have been a part of. It easily connects to a pyrometer, and is much more reliable for a accurate steel temperature reading than the spring type surface temperature thermocouples. The product is superior in accuracy because of the magnetic pull being constant vs a person pushing against the steel surface with a spring type thermopcouple.

Do you have a magnetic mount thermocouple rated for 1000 deg F?

Asked by: Derick Kekona
Thank you for your inquiry Derick Kekona. Unfortunately, we do not offer a magnetic mount thermocouple rated for 1000 F. The maximum temperature for the magnetic mount thermocouples is 482 F.

Can these be submerged in a liquid at 400C?

Asked by: TranscatFrank
Thank you for your inquiry! Unfortunately, these probes are not intended for liquid applications and should not be submerged
