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.

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.

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.

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.

data sheet shows need 10 seconds to read the full surface temperature, how about real time temperature logging? What is the response time?
Asked by: seraph3
Hi Seraph3
Thank you for the inquiry. Response time of the instrument would add to the response time of the sensor.
Best regards
OMEGA

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
