"The CheckitDirect models each offer one test method, while the CheckitDirect+ units are programmed for a number of different parameters. The units supply accurate, reproducible results very quickly. Other major advantages include ease of operation, ergonomic design, compact dimensions and safe handling.","The calibration and software-based adjustment options mean that the CheckitDirect is also suitable for use as a testing instrument.","The tests are conducted using either Lovibond tablet reagents with long-term stability and a guaranteed minimum 5 or 10 year shelf life, VARIO powder reagents or using liquid reagents."
