Introduction

DPG108 is a battery powered digital 
pressure gauge, making for easy 
on-site installation.  The DPG108 
uses a high-precision piezo-resistive 
pressure sensor.  The output signal 
is amplified by a high-precision, 
low-temperature drift amplifier.  
The signal is then fed into a high 
accuracy A/D converter for the 
microprocessor to process and then 
show on the LCD display.  

This flexible, simple to operate 
digital pressure gauge is safe, 
reliable, and easy to maintain.  
The DPG108 is widely used in 
hydropower, water, petroleum, 
chemical, mechanical, hydraulic, and 
other industries.  

Features
