Description
The DR3730 digital general pressure gauge is a cost-effective alternative to traditional analogue pressure gauges. It offers 1% FS accuracy across its full range and features a waterproof ABS shell for durability in tough environments. The large LCD screen ensures easy readability, while functions like recording maximum and minimum pressure values and zeroing aid in on-site monitoring. With low power consumption (less than 4.5mA), it can run on AAA alkaline batteries for up to 1 month.

So far, I tested one pressure gauge till 300 over bar (max 600bar optimal for my use). Got two more. Satisfied with quality and accuracy.
