Rated 1 out of 5 by from Chart recorder I bought this about a month ago. It's a nice unit, but the chart skips. I don't get a continuous mark for 24 hours.

Rated 5 out of 5 by from works well Have one in continuous operation for over 14 years...still running great. Easy to use and setup. Appropriate for an indoor installation.

Rated 1 out of 5 by from Never use them! We bought four of them. None of them is working satisfactory. Pen is vibrating and very thick line is generated. Actual reading is difficult to find out. It uses black pen and chart lines are dark brown, so you can not visualize properly actual reading line. It stops recording in between and again start during week cycle. I would never use it again.

Can the read temperature be adjusted? (we recently had ours calibrated and it's not reading correctly now, and calibrations won't be for another year or so). We have 3 running in water baths all at the same temperature and one is reading a full degree out

Asked by: Lab Rat
Thank you for your inquiry. There is no temperature adjustment on the CT87P Pressure Recorder.

Can it be used to record water pressures of a water distribution pipe?

Asked by: Hilo
Dear Hilo, yes you may as long as the pressure is within the operating pressure range, also this is rated only for steady static pressure.
