Acid-Resistant wetted material and components suitable for corrosion/acidizing testing
The M3600 Acid Option Rheometer has been on the market for over 10 years. The option features acid-resistant wetted material that is nickel chromium-molybdenum alloy (Hastelloy C-276). The unit also features all-sheet metals and stage plates that are coated with HCL acid-resistant paint. This provides an excellent resistance to corrosive samples and a variety of chemical compounds.

Two Operational Modes - Stand-alone or Integrated with PC
The M3600 can be used as a stand-alone unit, enabling users to create test sequences and record test data without the use of external equipment. It can also be connected to a Microsoft Windows PC operating our custom software for advanced test operations, test results analysis, and to export test data in spreadsheet format.

Durable, Reliable, and Affordable Digital Power
The M3600 Rheometer is equally suitable for use in both the field and laboratory because of its innovative design, rugged construction, versatility, and portability.

Software to cover all tests, from general viscosity to specialty
The included M3600Frac software is designed for measuring fracturing fluids, while M3600DAQ is designed for general viscosity measurement and mud testing. The Grace Instrument M3600 Acid Rheometer is a true Couette, coaxial cylinder, rotational rheometer. It is engineered to meet the various fluid rheology measuring needs of our customers, from on-site oilfield personnel doing single-speed tests in harsh environments to laboratory researchers doing advanced rheology testing.

The M3600 Acid Rheometer incorporates a steel framework, robust electronics and user-friendly interface for years of trouble-free operation and minimal maintenance. Clean-up between tests is easy and quick, and calibration is ideally performed with the push of a button. Used as a stand-alone unit, or with a Microsoft Windows PC and the included M3600DAQ and M3600Frac software. The unit provides versatile and affordable solutions to meet your rheometer needs.
