DX4095 Z-Meter Mini
Z-Meter Mini DX4095 mode is a portable tester for thermoelectric coolers express analysis. It uses the same measurement methods as standard DX4090 Z-Meter, measures directly three TEC key parameters (ACR, Figure-of-Merit and Time Constant) of separate and integrated thermoelectric coolers. The device has miniature, pocket size form-factor and it’s ideal for engineers and researchers dealing with TECs. Due to small size DX4095 has only external measurement interface – external clips – connected to Z-Meter.

Z-METER CLIPS FOR WB TECs (OPTIONAL)
By default Z-Meter is optimized for measuring process of TECs with terminal wires or mounted on a header with pins. In case of TECs with WB pads there is a special solution for Z-Meters – WB clips. Z-Meter WB Clip is an optional accessory with stainless steel fixtures, manufactured by request for a specific TEC size. The compact instrument with spring clip fixation has 4-wires measuring method probes, that don’t damage TEC WB pads during measuring process. The clip has a terminal connector compatible with all Z-Meter versions.
Z-METER BNC ADAPTER (OPTIONAL)
Z-Meter can be used also with standard laboratory measurement equipment like 4-wires BNC Kelvin clips or similar tools with BNC connector. For such cases TEC Microsystems provides BNC adapter, that allows to work standard BNC cable sets. Z-Meter BNC adapter is compatible with all Z-Meter versions.
