Specifications and Compatible Tools

The MKS 628 Baratron measures 0–1000 Torr with ±0.1% FS accuracy, operating on 24V DC power. It features a capacitance-based sensor and 0.1% full-scale repeatability. Compatible tools include:

MKS 628D (2015–2020 models)
MKS 628E (2021–2023 models)
MKS 628C (2010–2014 models)

Avoid pairing with MKS 628A (2005–2009 models), as its analog output interface is incompatible. Always confirm compatibility with the specific controller model. Units must be matched to a compatible power supply and signal conditioning module.

What to Check Before Buying a Used in 2026

Verify calibration certificates: Ensure certificates are dated within 12 months of 2026 and include traceability to NIST standards.
Test with a pressure calibrator: Use a Fluke 729 to validate accuracy at 50% and 100% of full scale. Reject units deviating by >0.2% FS.
Inspect RF-hour count: Reject units with >40,000 RF-hours unless for secondary applications. Primary use requires <30,000 RF-hours.
Check physical integrity: Look for cracks in the diaphragm or corrosion on the housing. Replace units with visible damage.
Confirm serial number match: Cross-reference with OEM records to ensure the unit is not flagged for recall or defect.
