Innovative Design with Dial-Reading Settings
The M3400 is a 9-speed Couette coaxial cylinder rotational viscometer and incorporates years of customer feedback into its design. The M3400 features a steel framework and robust electronics and 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 tests. The innovative design and rugged construction of the M3400 Viscometer makes it versatile and portable--whether operation is in the field or in the laboratory.

Hassle-free Speed Change
Currently, industry standard viscometers shift through different rotational speeds with a control knob that requires some finesse to operate. The M3400 takes all of that hassle away with a control pad, allowing any speed at any time.

One-touch Button Starts Tests
The M3400 comes pre-programmed with the popular test sequences: 10-second gel strength and 10-minute gel strength. With the touch of a button, the manual shifting of speeds in these processes are eliminated. This results in more repeatable test results.
