Vacuum gauge with combined piezo/Pirani sensor VD85

digitalUSB

The versatile VD85 vacuum meter with Piezo/Pirani combination sensor with data logger and USB interface reads pressure over 7 decades in the rough and fine vacuum range from 1200 to 5e-4 mbar. Overview VD85 compact vacuum meter Piezo/Pirani: - Wide measuring range due to combined piezo/Pirani sensor, ideal e. g. for the maintenance of vacuum pumps and systems - Excellent long term stability - Long-lasting Pirani sensor with durable, elastic helix filament - Optimized temperature compensation for stable measuring values - Integrated data logger for up to 2000 measurement values Overview VD8 vacuum meters: - Variable: VD8 compact vacuum meters can be used as a portable instrument or for permanent installation in vacuum facilities. The gauges can be operated by a battery or a plugin power supply - Flexible connection: VD8 vacuum meters can be placed directly into a vacuum chamber, connected to an appliance with their flange or with a suitable adaptor - Min/Max memory function: Storage of minimum and maximum pressures achieved during measurement - Long battery livetime: Due to cycled measurements, the compact vacuum meter reaches a high battery lifetime; the user can choose between automatic switch off (time adjustable) for battery saving or continuous operation - Pressure units: mbar, Torr, hPa - Data export: USB interface for easy push button data transfer to PCs, but no PC connection is necessary during measurements - VacuGraphTM Software: To visualize, analyze and save measurements on a PC (lite version free of charge)
