The MKS Measurement Head is a key component of the SRG-3 Spinning Rotor Vacuum Gauge System, delivering high-precision, PTB-traceable vacuum measurement. Operating by detecting viscous drag on a magnetically levitated spinning ball, it accurately measures pressure proportional to molecular density in the chamber. Designed for calibration and metrology of other high-vacuum sensors, the system achieves 1% reading accuracy from 1 x 10-2 to 5 x 10-7 Torr (mbar), and can operate with reduced accuracy up to 1 Torr (mbar). Supplied with a 3 m cable, it integrates seamlessly with the SRG-3 electronics module, featuring RS232, USB, high-resolution analog output, and dual trip relays. The SRG-SH700-V3 meets CE and RoHS compliance standards, ensuring reliable performance in demanding lab environments.
