圖拉特真空計(jì)vd83
VD83 digital vacuum meter measures absolute pressure in the fine vacuum range. It is equipped with USB interface and can be used as data logger (save up to 2000 measurements).
The VD83 can be operated with battery or external power supply making it ideal for either portable or stationary applications.
描述
Temperature compensated, metal sealed Pirani sensor with durable helix filament
High accuracy, excellent repeatability
Min/Max memory: Storage and display of high and low values
Gas correction factors for correct pressure readings
High battery life due to clocked measurement
The sensor is well protected against condensing solvents
Pressure units: mbar, Torr, hPa
Battery conserving auto-off mode or continuous operation
