Description
Advantages: automatic zero calibration, rapid measuring cycle (approx. 3 seconds), large digital display, SMD microprocessor technology, LEDs with long-term stability, suitable for use as a testing instrument, uses Lovibond® tablet reagents or vial tests with long term stability, fully equipped unit supplied in a case, automatic switch-off
The CheckitDirect models each offer 1 test method, while the CheckitDirect+ units are programmed for a number of different parameters. The CheckitDirect units supply accurate, reproducible results very quickly. Other major advantages include ease of operation, ergonomic design, compact dimensions and safe handling.
The LEDs used as a source of light have long-term stability giving monochromatic light emission with low power consumption.
As it is battery operated, the unit is suitable for both field and laboratory use.
The tests are conducted using either Lovibond® tablet reagents with long-term stability and a guaranteed minimum 5 or 10 year shelf life or using Lovibond® vial tests.
