Responce would be needed if you are monitoring temp vs time. SS covered probles have a big time lag responce. Which is used for tank and inline probes. If you have an option use exposed sensors. If not get grounded for faster responce, un-grounded for less noise, and slower responce. RTD are highly accurate used them mostly for references.

Flowmeters. I use to have to measure rates down to 3cc/hour. Can you say sloooooow, liguid and gas. Where the gas was toxic. I alwas liked the lamilar flow, felt it was more accurate than the others. But its alway nice having tranduces in the 0-30" and 0-6"WC range, and a Big Budget. Made of HC276 wetted materials with a overburden pressure at 1500psi..... I think they cost $1200USD each in 1990, the last time I purchaed them.
I used Eurotherm Temp Controlers with scr's. With these I could do my own tuning for responce curves. I was able to have temp contol deviation of less 0.5F.

Since I worked with Hazardous materials all of the time. They (Arco) built a building specially to handle it. Restricted Access, tighter than our data center. I had single pass air (scrubbed), explosion proof rooms/bunkers. Designed to with stand a cubic foot of gas @ 30,000psi, catastropic failure = 5 sticks of TNT with no damage. I was paid to take thing to failure some times. Fun when you get to do that. A lot of the work I did, I watch come to market 5+ years later.
