15 Sep 2010 TEC Microsystems GmbH introduces Z-Meters - universal measuring and quality control instruments. The devices provide express control of TE cooler performance with high accuracy. Z-Meters have no analogs by provided measuring technique, measuring rates and QC possibilities
Z-Meters provide express control of the following thermoelectric cooler parameters: ACR, Z-Value, dTmax and Time constant (t). Time Constant (t) is the third parameter that characterizes thermoelectric cooler and can be measured by Z-Meters. RMT first in the world introduced routine measurement of TEC Time Constant as it is also very sensitive parameter (as well as ACR and Z-values) and useful additional criteria of thermoelectric cooler performance and reliability analysis. Accurate measurements are provided by four-wire Kelvin Clips scheme and metal housings that plays a role of passive thermostat for measured TE coolers at equilibrium conditions. Built-in digital thermometer provides precise (0.1ºC) control of ambient temperatures. Because of temperature sensitivity of rmeasured ACR and Z pareameter both of them are normalized to any specified standard temperature software selectable by User. Additional corrections are available for precise measurements to exclude affect of measuring environment. |
