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.

Rated 5 out of 5 by from Flat Stanley VLE Well, it's not Stanley but the flat ribbon thermocouple is excellent under heating tape. The application is temperature control in a 100 ml glass boiler of a vapor liquid equilibrium VLE, with a second ribbon thermocouple monitoring for failsafe shutdown.

Rated 5 out of 5 by from great product We absolutely love these probes. The head of the probe is about 1 inch by 1/2 inch and the magnets are extremely strong no problem staying attached even through thick industrial finished pipes and machine housings. rapid response time like all omega probes.

Rated 5 out of 5 by from Great product! This is the best magnetic thermocouple on the market! I have tried a couple of others that have a less than desirable magnetic force.

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.

Probe 88401K. What is its accuracy in the range 150C-200C?

Asked by: Leon
Thank you for your inquiry Leon. The accuracy on this thermocouple for the full 0 to 250 C range is +/- 1.1°C or 0.4% whichever is greater.

When I purchase the Thin Leaf-Type Thermocouples, does it comes with the calibration certificate? or the calibration must be paid separately and what is the cost? thanks, Huy Le

Asked by: Anonymous
Thank you for your inquiry Anonymous. The thin leaf-type thermocouples do not come with calibration. Please send a request for pricing for the probe and calibration at sales@omega.com

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
