Precision Combo Calibration Device
P/N 100-27-31

The Precision Combo Calibration Device is an essential component of every current-generation F/G Series Goniometer and Tensiometer. The device is required to establish a physical reference distance so all resulting profile measurements are accurate in both the x and y axes. All editions of ramé-hart's DROPimage software include a calibration routine which measures the height and width of a fixed dimension sphere or rod and then stores the results for all future measurements and contact angle calculations. This tool is available in two forms: p/n 100-27-31-U is the uncertified version and one is included with all new instruments; p/n 100-27-31-C is the certified version which ships with a certified calibration report with actual horizontal and vertical measurements traceable to a NIST Grand Master Set. The p/n for recalibration is 100-27-31-RE. We also can recertified a previously certified Precision Combo Calibration Device. The p/n for this service is 100-27-31-RE.

The video below shows how DROPimage is calibrated using the Precision Combo Calibration Device. For detailed instructions, consult the documentation for your edition of DROPimage or consult the how to guides on our Technical Support page.

Certified Fixed Drop Calibration Reference Tool
P/N 100-27-03

The Certified Fixed Drop Calibration Reference Tool includes (4) fixed sessile drops at nominal contact angles of 30°, 60°, 90°, and 120°. Use this tool with your calibrated ramé-hart goniometer to ensure that the instrument calibration is accurate and that your measurement procedure is correct. These drops never evaporate and are not affected by humidity, temperature, air quality, and other environmental factors. This product is supported on any edition and any version of DROPimage. Each tool ships with a Calibration Report and detailed instructions on how to use it.

Certified Pendant Drop Calibration Reference Tool
P/N 100-27-05

The Certified Pendant Drop Calibration Reference Tool includes (10) fixed pendant drops representing a variety of liquids. The surface tension of each of these drops can be measured using any version of DROPimage Advanced. The repeatable results will assure the instrument user that the tensiometer is calibrated properly and that correct procedures are in use for measuring surface and interfacial tension. The results are not affected by temperature, contaminants, air quality, humidity, or other environmental factors. Each reference tool ships with a Calibration Report and detailed instructions on how to use it. The video below shows how a simple surface tension experiment can be created and then how the first of the (10) pendant drops can be easily measured using DROPimage Advanced.
