ISL's safe, easy to use NCK2 5G Noack evaporation loss analyzer enables the most precise testing possible to meet increasing QS/QA requirements in full compliance with CEC, ASTM & IP methods. Excellent repeatability and reproducibility have been proven through numerous international round robin programs. 

Designed for routine day-to-day work in labs with high sample workloads, the NCK2 5G test initiates with a few simple keystrokes. The test can be started with either a cold or hot heating block, significantly increasing test productivity. Smart assistance features automatically alert the operator if any test device is not properly set, and the instrument carefully tracks sample temperature and vacuum throughout the test's duration, providing a digital display of each and recording the values to memory. 

NCK2 5G's advanced quality control features -- including traceable automatic calibrations with lock-out control and detailed test reports with tracking numbers of all measuring devices -- fulfill strict ISO 9000 quality system requirements. The metal temperature probe is delivered with an engraved serial number and traceable calibration certificate. Extended local memory capacity, graphic printer connection and PC link enable powerful, flexible results management.


Extends NCK2 5G's application to any products requiring evaporation loss measurements between 100 and 300ºC (i.e. waxy products; thin base stock oils; hydraulic, gear box and transmission oils; and special liquids, including synthetic oils). Internal studies show good correlation to Woods Noack results. More laboratories can now benefit from ISL's Noack evaporation loss analyzer, which enables the safest, easiest to use and most precise testing possible to meet increasing QS/QA requirements.


Recommended for use in QA/QC application of petrochemical laboratories, ISL's CRMs are specially formulated to test the accuracy and precision of automatic Noack instruments. Two samples are available: high value (about 17 w%) and low value (about 11 w%) of volatility. Certified values are determined by statistical study of data obtained during Round Robin testing. Products ship in 1/2 gallon containers and include a certificate.
