Hello fellow ACS members. I'm looking for a model of digital timer that displays in seconds only, and at least to the tenth/sec. The only product I have found is the defunct Lab-Line(r) Kwik-Set Lab-Chron No. 1405- and while it may be a fine timer, it would be nice to have something NIST traceable and quiet (this is electro-mechanical). This would mainly be used for capillary viscosity testing. I remember using an alternative to the Lab-Chron that was made specifically for the petroleum industry, and in Texas (I believe)- seems like they were around $600 US/ea!!! I assume with the right materials I could probably make my own...Oh, and the reason for displaying seconds only is that this (if it exists) is a fix to a problem my company is having with production quality testers forgetting to change 1.52.28 to 112.28sec from stopwatch to viscosity formula.
Re: Time measurement: Alternative to old Lab-Chron?
What about an electronic stopwatch? A quick web search brings up several "seconds only" stopwatches, for much less than $600. See, for example, Control Company http://www.control3.com/index.htm. Theywould seem to have NIST traceable stopwatches for what your looking for, and they specifically mention viscosity measurements.
