We have been using the Rudolph Research Autopol IV in th General Analytical lab in Pearl River since November 1996, and we are v_ery pleased with its performance. The calibration procedure is straight-foiward and easy to perform. The temperature correction feature makes ·checks for system suitability with NIST traceable quartz plates quick and accurate. We have the instrument connected to a printer, so we are now able to obtain a hard copy of samp,e_measurements. Overall, the instrument has been trouble-free and easy to us_e. Combined with the excellent customer service provided to me by Rudolph Research: on eyery occasion I have contacted them, I highly recommend the instrument.
