We are replacing our vintage hygrothermographs and I am wondering what you use and like.
We have only two small labs to monitor. We're +/- 1 Deg C in one and +/- 5 Deg C in the other. RH is +/- 3% in both.
We're leaning towards digital recorders w/sandisc cards but I'd like to know what is is in use in other labs.
We use a duel channel Fluke 1620A temp monitor and we chart it to a computer via a serial cable. Then we can save the data as excel or print the reports from the software. The system works ok enough for the Army. I'm sure you can find something better.
