Very easy to use, precise measurement and all of that for low price. Inspite of it some disadvantages that I found: 1. The capacity of device's memory very low, but for my test work it was sufficient. 2. Box for testing bottles for 0NTU and 100NTU sits to tight so if pull it strongly you may scratch the glass of testing bottles. That's all I have found. Thank You SPER SCIENTIFIC.

Amazingly simle and fast to use. Gret that it cimes with case and calibration solutions.
