BPZ2008 Pressure Gauge/Switch
Introduction of digital pressure gauge:
BPZ2008 is a cost-effective digital gauge specifically designed for measuring corrosive gases and liquids. It utilizes a solid-state sensor, which guarantees accuracy and longevity due to its micro-machined silicon pressure sensor (MEMS) and absence of moving parts. The pressure is transferred to the sensor via stainless steel diaphragms and silicone oil, ensuring reliable performance. This gauge's unique ASIC design enables it to offer exceptional value without compromising on quality.
The device features a large LCD digital display with an 18mm (0.71") height, which eliminates the need for guesswork when taking readings compared to an analog dial gauge. Zeroing the display can be easily done with the push of a button. Additionally, to conserve battery life, the unit has an auto-off function that can display pressure readings for 1-15 minutes (optional) before automatically shutting off.
