This is a tool for all professionals in HVAC and industry field. AMI 300 can measure, store up to 12,000 values and restore on PC (wireless communication) up to 6 parameters alternately. It measures pressure, temperature (RTD, thermocouple, NTC), humidity, air quality (CO/CO2), air velocity and airflow (vanes or hotwire), tachometry. For visual comfort, the instrument has a large colored display (with bargraph) and easy browsing is done thanks to its joystick on keypad. It can be equipped with wireless probes (Radio frequency) supplied with a multifunctional key allowing measurement and settings. Furthermore, the tool can be equipped with interchangeable measurement modules which are individually calibrated and are automatically recognized by the instrument thanks to the Smart-plus system. These measurement modules are available for pressure, thermocouple temperature (4 channels), climatic conditions (hygrometry, air pressure and temperature) and current/voltage parameters.
