es-d series electronic density balance:
es-d series electronic density balance adopts the archimedes principle, is a combination of electronic balance and density-testing device, can either weigh or test density, easy operation and testing accuracy can reach 0.0001.
this series is widely used in the industries of electronics, rubber, plastics, wire and cable manufacturing, shoemaking, sports goods, food and cosmetics etc.
main features:
l this series can realize the measurement of solid and solid volume, liquid and concentration
l density, volume, concentration, purity read directly, reduce tedious calculation.
l full stainless steel density stand.
l standard rs232 communication port, realize the communication between data and computer, printer or other device.
*  select the below hook weighing device.
*  select usb interface.
*  select thermal printer.
*  select glass counter weight (only for solid liquid double-use density balance)
