DX4090 Z-Meter

Z-Meter DX4090 is the most balanced device for thermoelectric coolers express analysis. It measures directly three TEC key parameters (ACR, Figure-of-Merit and Time Constant) of separate and integrated thermoelectric coolers. The device has two measurement interfaces — internal chamber (works as a passive thermostat) with connectors and external interface with clips. DX4090 has built-in temperature sensor for accurate TEC ACR calculations and build-in function of TEC polarity check. DX4090 is recommended for express quality control of small and mid-size TEC batches, R&D analysis and TEC integrating/assembly process optimization.

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.
