Questions

Question
What's the sample rate of the 475 digital manometer series? Is there an average function of the the past samples?
Answer
The sample rate is 1 reading per second. There is no average function of past samples.
Question
I have four Series 475 Mark III Handheld Digital Manometers that we have had for one year. I would like to have them calibrated, but I do not know where to send them. Do you offer a calibration service for the products you sell?
Answer
Yes, we provide NIST calibration for the 475 series both at the time of purchase and afterwards. Please contact one of our customer service representatives at 1-800-872-9141 and provide them with your model number(s).
