This time the pH sensor has arrived after a lot of problems faced during the delivery process where the shop assistant does not update the order status of the item. The pH sensor comes with the pH probe, pH module and the buffer pH solution. I have to wait until the buffer pH solution arrived first in order to test the pH sensor because somehow there is no buffer pH solution in the parcel received.
I have informed the shop assistant about this problem. The shop assistant said that the cost of the delivery will be covered by them and the calibration solution will be arrived in 1-2 working days.
