KEYCOM’s capacitance method/system is ideal for dielectric constant and dielectric loss tangent measurement of flat plane, liquid, or gel and
capable of taking measurements in the temperature range from liquid nitrogen
or -70 to 400 degrees Celsius.
Different types of electrodes are available for specific materials of specimens; DPT-009 for plate, thin film, gel, DPT-012, DPT-013-050 and DPT-013-200 for liquid, and DPT-2141 for ceramic insulators.
DPS17 can be interfaced with, and controlled by your PC, automating time-consuming temperature/humidity characteristics measurement.

*Windows PC is required.
*Thermostat chamber is required for temperature above or below room temperature.
ASTM D-150, JIS C2101, JIS C2141, JIS K6911 Compliant.
(Please specify the standard of your request)
