Suggestions needed for which contact-less temperature measurement Ir sensor

Hello,
I already own a Heimann LHI958, and am not sure if it is feasible to measure temperature over a distance of atleast 2 feet. I need suggestions on which sensor should i use for the task mentioned.
Your help would be appreciated
Thanks

To get a suggestion you should specify what you need.

I cannot find a datasheet for the sensor you already own. The data I found show a very large field of view so getting a temperature in 60cm distance might be difficult but that depends on the target application.

So either post a specification of your needs or describe the intended usage in great detail.

Hello,

Please specify more what you need to do. There are hundreds of thermal sensors/cameras.

I.e. Those sensors can go up to 13m but not sure if it fits your accuracy.
