This is my second order; the first set of sensors / display has been working successfully since Oct-2020 (I confirm its operation under -28C env. temp and 1.6/2.2 Bar pressure). As for this set I have not installed it yet, but tested: - display: was connected to a 12-volt/2A power supply from satellite receiver; - sensors: were put into an empty 5L plastic bottle and pressure was applied by simply sitting( ;-) !) on it (zeroes on the display changed to 0.1s Bars for each sensor). So everything seems to work.
Received thank you very much.
