8120 Series High Performance Compact Digital Pressure Meter 
The 8120 series is a compact digital pressure meter while maintaining high performance equipped with the tracking function (auto drift cancel). Depending on required rated pressure, 5 models are prepared as shown in the following list. The pressure meter can be offered as OEM with your required joint holes, outer case design and color. And it can be supplied as parts kit to be installed in the system. The model with wet parts materials for the inert specifications whose max. pressure is up to 20MPa is available.

8122 10 MPa
8123 20 MPa
8124 50 MPa
8125 100 MPa


8150 Digital Pressure Meter for micro volume 
Generally, flush diaphragm pressure method is used as a pressure sensor for the scientific instruments. It detects pressure which is applied to certain area by the strain gauge and convert it to the signal. Disadvantage of this method is that the sensor requires certain area. Recently, micro flow and nano flow of the pumps are used so that dead volume of the sensor has not been neglected. Then this method has caused contamination and other problem. Internal volume of the sensor equipped with the 8150 is as small as 4μl. And its internal diameter of the sensor is almost the same as that of tubing, so no contaminations occur. By using the 8150, now it is not necessary to use the pressure sensor with 100μl internal volume while the flow rate of the pump is a couple of μl/min. To meet smaller volume requirement, the pressure sensor with internal volume 1.6μl can be offered.
