Great service!
We order from Omega on a regular basis. They almost always have the exact part we were looking for and we always receive our orders in a very timely manner in the condition expected. Top notch.

Timely shipping for a timely needed product
Thermocouples that arrive on time, with no abnormalities and never have to be returned.

Sturdy and Accurate
Have used these products over the years and they have always been reliable and sturdy despite the abuse they get.

Quick Disconnect Thermocouples
Much like all of the other OMEGA products I have used over the years these TC's are a GREAT PRODUCT! Your new website is awful!

Disappointed that the mini connector is separate.
My company has been purchasing this Tcouple for decades. The latest batch came with no connectors. Nobody informed us at time of purchase, and we were charge for rush shipping to a customer that was unhappy with the delay.

Reliable TCs
The TC assemblies are reliable and long lasting. The delivery was prompt and allowed us to begin testing without delays.

Ordered a mouse, got an elephant
Omega has great equipment but lackluster order fulfillment. I ordered a "Quick Disconnect Thermocouples with Miniature Connectors", part KMQSS-125U-12. Title says "Miniature Connectors", what I received was probe with standard connectors. Third time I've ordered this part, first two times got miniature connector, this time a standard connector. Called twice, emailed twice, sent two photos. No replacement, no refund. Not sure how to order next time to ensure I get the right part configured correctly.

Works well for what I needed it for - pharmaceutical products.

when would I use a grounded versus ungrounded thermocouple?
Thank you for your inquiry David W. You would use grounded when there is no risk of any electrical noise affecting your measurement and you want a fast time response. You will used ungrounded to minimize the electrical noise on the system however your time response will be slower.

In the part no for a thermocouple, what is the difference in the first three letters KMQ vs. SCA?
Thank you for your inquiry. KMQ's connectors are molded to the probe and are non-removable. SCA's have removable connectors. Both are Type K Thermocouples.

Do you have guidelines for minimum bend radius? I'm not seeing any in the datasheet.
The minimum bend radius would be 2 times the probes diameter.

What is a maximum diameter of the cable connected to the TC? Could you recommend a cable to connect the TC for length of 80m aprox.?
There is no cable or lead wires attached to the probe. You will need to use a mating female connector and extension wire to extend the run of your circuit. The mating connectors can only handle up to a 20 gauge wire. The maximum distance you can run a type E 20 gauge thermocouple wire is 140'.

What is the response time
Thermocouple response time is a function of the probe diameter and the junction type such as Grounded, Ungrounded and Exposed. The link attached will help you determine the response times of various diameters of thermocouples with the three aforementioned junction types.

Does this item include the female connector?
Thank you for your inquiry. These products do not come with the female miniature mating connector. Sold separately.

I am using the probes with temperature range of 0-260 degC. I make sure the tip is always measuring within range. But, some portion of the sheath far away from the tip may be under a higher temperature, say 300 degC. Is this okay?
Thank you for your inquiry. No the temperature range of the entire sheath is 0 to 260 C. If you exposed any part of the probe to a temperature higher than the rated temperature, it will lead the probe to have a reduce lifetime and failed prematurely. If you need to measure higher temperatures, please get a probe rated for that maximum temperature.

Are your assemblies with exposed junction considered pressure / vacuum tight up to the connector? I want to install one in a vacuum oven. Have used sealed probes before, but need quicker response with exposed junction.
Hello, thank you for your question.
Although the probe is epoxy sealed we do not recommend using ones with exposed junctions in a vacuum environment because air will leak through from the the outside connector side of the probe into the vacuum.
