Megotec MTA300

Megotec_product_photo Answering the need for a reliable lab analyzer pure water feed system, Hydro, Inc. Atlanta GA has developed the Megotec MTA series ultra pure water system. Megotec will distribute Type I Laboratory grade water as specified by ASTM, CAP/NCCLS and USP to chemistry analyzers and various other points of use within your laboratory. Producing water quality with minimal (low) background noise, Megotec may also be used with mass spectrometer equipment. With a production rate of 94.6 LPH, and the incorporation of our internal semi-automatic emergency bypass feature, Megotec can feed more than one (1) analyzer at any given time (depends upon certain equipment feed requirements). If you are interested in working with a personable water company that manufactures water systems in the U.S.A. (Georgia) and is backed by a personable service department with an outstanding Preventative Maintenance Agreement (PMA), then please contact Hydro, Inc.
