Top 5 Positive Customer Reviews for co2 meter
It was slight delay of shipping because of Chinese New Year but after that the parcel came to Latvia very quick. The product quality seems ok. Defiantly recommended product and seller
The only problem is that there are no user instructions in English. Only in chinese language. Correctly measured after several days. This is because autocalibration start after 4-5 days.The smallest during this period is considered to be 399 ppm. If the room is not ventilated, there will be an incorrect calibration. Autocalibration periodically.
Very Well packaged in its carry case and the unit looks well built. The Store was excellent and the items were shipped into South Africa very quickly, thanks Steven,. We were let down by the South African DHL agent's very slow bureaucracy which held up the shipment for two weeks without them seeming to be very concerned about it!
