DX4190 Z-Meter Multiposition
Z-Meter DX4195 is the must-have device for TEC manufacturers or consumers with serious TEC volumes. DX4190 allows to implement 100% Quality Control in all stages of mass production with no compromises. The device measures directly three TEC key parameters (ACR, Figure-of-Merit and Time Constant) for up to 10 thermoelectric coolers simultaneously. DX4190 can be used with separate (not mounted) TECs by manufacturers or consumers at income/outcome control, or for TECs quality control and performance testing in the end-product with TE cooler integrated.
DX4190 Z-Meter consists of two units – Control Unit and Measuring Unit. The Control Unit is the brain of Z-Meter DX4190 system with 10x independent Z-Meter measuring channels. Control Unit works together with Measuring Unit attached, or can operate with External Clips (without Measuring Unit attached) if required. This gives enough flexibility for mounted (integrated in device) TECs testing. Both units have ambient temperature sensors for precise and accurate measurement results (cause TEC performance parameters depend on ambient temperature).

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.
