VD800 Compact Vacuum Meters

Functioning 
The VD800 vacuum meters measure absolute pressure in a large range of 2000 to 5e-5 mbar and additionally relative pressure in the range of -1060 to +1200 mbar. Their big graphic LCD display shows current measurement values and pressure graphs as well as minimum and maximum pressure with the 4+1 membrane keypad providing a comfortable, menu-driven operation. An integrated data logger saves multiple measurement series with their RTC data. With sampling rates from 20 ms to 60 s the instruments are not only of interest for fast vacuum processes but also for long-term monitoring. If required, an alarm function gives an optic or acoustic signal when reaching a defined threshold value.   

Read-out and analysis of measurement values 
The USB-C interface – or optional Bluetooth® LE for wireless data transfer – allows a direct read-out of the measured data and the export of measurement series stored in the data logger. Using the Thyracont VacuGraph™ software, the user is able to comfortably save and analyze the data as well as to start an online measurement.   

Smart solutions 
Intelligent energy management provides for a long battery performance of the VD800. Using a standard power supply users can swiftly charge their VD800 via its USB-C interface. The new modular design allows an easy exchange of contaminated or defective sensor heads by authorized personnel on-site, reducing maintenance time and costs to a minimum.  

Compact, precise, flexible 
The models: The VD800 is to be used with an external Thyracont USB transducer. It is thus ideally suited for applications with reduced space or to read-out numerous permanently installed sensors. The VD810 with a resistant ceramic sensor measures independent on gas type in the rough vacuum range. The Piezo/Pirani combination sensor of the VD850 covers a wide measuring range in rough and fine vacuum with highest precision and accuracy. 

Variably applicable  
The VD800 vacuum meters can be connected to vacuum pumps or plants, linked to external sensors or directly placed into vacuum chambers. Mobile use or permanent installation in vacuum plants – both are possible. The compact VD800 are perfect for service use, quality control and maintenance work or for leakage testing via rising-pressure method.
