hello, in looking at producer (hti-meter.com) documentation it would be interessant to increase the choise among available range of the producer specially with HT-1892 (+- 1b) wich can be also usefull as non différential use because precise gauge(diamétre 80 or100mm) in this range is not easy to find and HT-1891(+- 0.34b) too regards
Thanks !
