Arrived from two days and still not tested. For the moment I can express myself on constructive quality: poor. Badly made plastic, one of the two wires for connecting the battery is unsoldered and I can only use it at current. That he was not professional could be guessed from the price but I didn't think about these levels. I hope to evaluate it as quickly as possible.

Built well and with a bright display, I find it inaccurate, however, if left as I constantly do in the water to control the aquarium's PH. I was surprised that in the pack there was not even a packet to carry out the calibration of the probe at PH 7, essential for the first start-up of the instrument.

It is advisable to calibrate the first measurement of the instrument. Quite accurate measurement. The probe protection system is excellent. For the Retailer. I would include batteries.
