Digital tensiometer HK-971

HK-971 Automatic Petroleum Oil Surface Tensiometer Overview HK-971 conforms to ASTM D971 Standard Test Method for Interfacial Tension of Oil Against Water by the Ring Method. It can be used to replace chemical method with physical method, and can be used to measure the surface tension value of a variety of liquid quickly and accurately.HK-971 can also be separated from the use of the computer, built in LCD digital display and small printer, can be stand alone operation, can also be connected to the computer control to observe the dynamic changes in tension curve. Features 1. Large color LCD display screen, English prompt, menu operation, fully automatic testing process 2. Automatic temperature compensation within 25℃ to eliminate the influence temperature imposes on tension value. 3. Functions of auto correction, auto testing, calculation, results displaying, and storage under power off circumstance 4. Main body is equipped with hurricane globe, which lessens influence outside matters impose on testing results. 5. Automatic lift of the lift platform ensures a steady environment as well as high accuracy. 6. Tester program can be updated accordingly if related national standard revised. 7. Tester can work independently and can also realize network management via connection with laptops or microcomputers through USB interface. 8. Tester adopts enclosed magnetic pot type sensor and multi-point calibration of uniform space technology, which improves the repeatability and reproducibility of testing results.
