Feature :
1, the core of the product using the new intelligent micro-processing chip, stable and functional and
practical performance.
2, LED displays the current pressure or level value;
3, the pressure or level can be set to start or stop according to their needs;
4, four LED products according to customer needs three units can choose: Mpa, KG.F / CM2, PSI
5, can be set high and low pressure or level alarm, and relay or optocoupler output to the control device;
dual relay output (SPDT) switch;
