Sino HS318 Electric Comparator (Oil)

The HS318 Electric Comparator employs the gas-liquid push principle. The extra air sources provide active power to pre-pressure for the entire calibrating system, perfectly replacing the heavy and complex handwork operation. This instrument is simple to use and generates the required testing pressure quickly, providing precise pressure control, and only takes less than 5 seconds to stabilize the pressure. Following the points mentioned above, its a main advantage is that it saves both effort and time, making it ideal for heavy and repetitive calibration work.
