Previously purchased material number TT-T-30-SLE(ROHS) no longer is offered on your website. It appears the ROHS compliance is not longer available? Neither copper nor constantan contain lead, and other mfg. PFA insulated cable is ROHS compliant.

Thank you for your inquiry. Omega still offers the TT-T-30-SLE wire with the ROHS compliance but you'll have to enter the part number manually in the order box using the ROHS suffix. For example TT-T-30-SLE-100-ROHS. If the specific wire size that you are wishing to order fails to be valid please contact the Sales Dept and have them assist with that order. Omega's standard spool sizes are 25', 50', 100', 200', 500' and 1000'.

How fast is the response for this type of wire? How long would I need to expose this wire to an environment to obtain an accurate reading? What is the time needed for this wire to reset to ambient temperature?

Thermocouple wire itself does not have a response time. If you were to weld the two wires together to form a sensing junction and if the weld bead that was formed were no larger that 2.5 times the diameter of any one wire leg you might see a response time of about 4.5 seconds on an AWG 24 wire. If the wire size is larger the response time will be longer, conversely, smaller gauge wire can yield a faster time response. This again is determined by the method of forming the sensing junction where the two wires meet.

What does "high performance", noted after the Neoflon & PFA in the Insulation column in data sheet, mean?

Thank you for your inquiry Tabull. The high performance just means that it offers a combination of excellent dielectric properties across a wide temperature and frequency range, and the highest level of chemical resistance of most insulated wires.

I am using FF-T-20-SLE-1000 and my readings keep jumping around alot like 50 degs at a time. Does anyone else have this problem?

Thank you for your inquiry JOELBARB0. Due to the complexity of your question, please send an email to temp@omega.com and one of our engineers will assist you in finding this information.

Whats is the response time for the wire type T-30?

Thank you for your inquiry! The response time is a function of the junction type and the wire/probe diameter. Please see this technical reference for specific response time data: https://www.omega.co.uk/temperature/Z/ThermocoupleResponseTime.html
