Thermistor value for 732A Reference 10V Standard

Hi,

Some years ago I was working with a conductance measuring product that maintained sample cells to 2 millidegrees, and 4 millidegrees front to back of the temperature bath for a stability held week by week at any dialed setting, but accuracy between dialed temp and actual was only expected to be about a degree. I would expect something similar for this, maybe not the 2 millidegree stability though, that was hard to achieve.

Has anyone actually measured the internal temperature of the oven (in degrees
C)?  Since the operating temperature of the 732A is spec'd at 40 C, I suspect
that it is about 45-50 C, or so.

According to the manual it's 48 ± 2°C

And I also suspect that temperature stability
of the oven is more important than absolute accuracy.

You'd be correct :-)

I didn't expect the large outpouring of knowledge!

Nobody expects the large outpouring of knowledge! (with apologies to
M. Python)
