HORIBA APMC-370 Air Pollution Multi-gas Calibrator

Multigas Calibrator for AP Analyzers

Dilution of gases with high accuracy and precision requires high quality MFC’s, especially for high dilution ratios and ranges. Consequently HORIBA’s APMC-370 is equipped with digital MFC’s. These MFC’s are factory calibrated, optional also with a special Polynomial Calibration. HORIBA Europe‘s APMC-370 is designed to calibrate gas analyzers manually, remotely controlled or automatically. It is installed in air pollution monitoring stations for quality assurance in the laboratory and also in the production of gas analyzers.

A special feature of HORIBA’s APMC-370 is the big size touch screen panel, for ease of operation. Characteristic of the operation of HORIBA’s APMC-370 is the intuitive, simple and user friendly menu (for instance control of flow rate: µg/m³, mg/m³, ppb, ppm, automatic cycles etc.) Via the touch screen it is e.g. possible to enter span gas concentrations or to start automatic routines like multi point calibration cycles.
