Review on HM Digital Waterproof pH and Temperature Meter, 3.3 x 8.5 x 2 inches, White by Anastazja Simiska ᠌

Previously, I bought a similar device from China, worked faithfully for several years. Having bought the same device in a store in 2022, but with a more convenient lid, I took out a device from the box in which something dangles inside. After checking on the calibration solutions, all the control points were in place, and I left to measure the water, upon arrival, I found that the device rebooted during the measurements. After finishing the measurement and upon arrival at the office, the device was put on a shelf and, naturally, in a lid (cap) solution for storing KCL, after 3-4 days there was a call for measurement, before leaving, I measured the calibration points, and they floated away by about 0.4- 0.7 is far from an error. When measuring, it rebooted, something was pounding inside. Draw your own conclusions, I personally do not recommend buying ! P/S. after the review - there was an aggressive reaction of the store to a negative review. it’s scary to imagine what will happen when I have time and another device to replace this one in work and apply for a guarantee. good luck.
