Multimeter Expert-1234 chemical
Multimeter Expert-1234 chemical Multi-parameter instrument - pH meter / ion meter / oximeter / thermometer / photometer / conductivity meter / voltmeter / ammeter / potentiostat / COD meter / meter pressure. Designed for field measurements and research work. One device actually not only replaced 4 serial devices (liquid analyzer "Expert-001", conductometer "Expert-002", photometer "Expert-003", pH meter "Expert-pH"), but also has new additional measurement modes. The Expert-1234 chemical multimeter provides the ability to output information to a portable thermal printer (receipt tape, thermal labels). The measuring transducer of the Expert-1234 chemical multimeter is flexibly equipped with sensors and cells depending on the user’s tasks. Manba: https://www.nv-lab.ru/catalog_info.php?ID=9398
