To mcguire,
  There is growing use of IR video systems for plant maintenance thermal surveys.  Portable units can locate overheated mechanical power transmission components (bearings, gear boxes, seals), electrical cable and insulator incipient failures,  thermal insulation internal damage, and hot gas leaks.  Your colleague may not need a lab service, but might be able to rent equipment or have a contractor perform services at his site.
  One vendor advertised in Plant Services magazine,
www.infraredsolutions.com ,
has demonstration on webpage and offers free on-site demo.  Measurement capability to 1200 degC should be within the needs of your colleague.  They probably could provide references to IR contractors.
Two other vendors
www.mikroninst.com
www.raytek.com
have extensive product lines.  Globalspec.com lists many others under 'thermal imagers'. Finally,
www.snellinspections.com
www.snellinfrared.com
is service advertiser in the magazine with history to 1983.

What I get from the past threads is that member ko99 is in the business and generaly does study for heat sinks. The link is www.ecoolingbiz.com

Regards,

Mcguire, the "Measurement & control instrumentation engineering Forum" may have more suggestions for your friend.

Thanks for the lead.
