1. INTRODUCTION
The portable Z-Meter
provides measurement
of performance and
operational operating
parameters of
thermoelectric (TE)
modules. It can
measure operation and
performance of
thermoelectric cooling
modules, thermoelectric generators, and thermoelectric sensors.
The performance parameters are the following:
AC Resistance (𝑅),
Figure-of-Merit (𝑍),
Time Constant (
),
Maximum Temperature Difference (∆𝑇).
Maximal temperature difference ∆𝑇 only for single stage TECs.
Because of direct correlation with Figure of Merit is calculated within Harman
method approximations.
Additionally new functionality of this device in the family of Z-meters –
measurement of operating parameters of TECs:
Operating voltage (𝑈),
Working temperature (𝑇 or 𝑇 ).
Measurements of temperature can be used for evaluation of cooling
temperature of working TEC (𝑇) if thermal sensor is placed on TEC
cold side. Or to measure ambient temperature (𝑇)of performance
measurements – if to place near TEC.
The Z-Meter provides testing of various types of single- and two-
stage TE modules. It is possible to evaluate quality of more-stage TE
modules by the measurement of electrical resistance.
The parameters are measured at the ambient temperature 𝑇. The Z-
Meter provides recalculation of 𝑅 and ∆𝑇 to another temperature
value from the Ta vicinity.

With the device it is also possible to test thermoelectric generators
and sensors: voltage at thermoelectric generator (TEG) provided by
temperature difference; response of thermoelectric heat flux sensor
ADVANTAGES
Express testing
performance of single stage
and multi-stage
thermoelectric modules.
Testing performance of TE
modules integrated into
optoelectronic devices
(photodetectors, lasers
etc.).
Operating parameters
measurements.
Compatible with other Z-
Meters of PL Engineering
Devices Family.
FEATURES
.Portable device. Metal
housing.
Measurement at direct and
reversed current.
Results normalization to
standard temperatures.
Low power consumption.
Long autonomous
operation.
