CEM, originating from Shenzhen, is a supplier of measuring and testing instruments. Despite the fact that these products have been available from TME for a long time, there are few new solutions at TME that deserve to be noticed. These are testers and meters for professionals, characterised by high ingress protection rating and resistance to environmental factors – dedicated for installation and maintenance works in electrical and industrial systems.

used in harsh conditions.
Testers and voltage indicators DT-9332 and DT-9231
DT-9231 and DT-9332 to are two-pole voltage indicators which allow to detect AC and DC voltage and take measurements up to 1000V. The testers are equipped with polarisation indicators in single-phase networks, while in three-phase networks they display information about the phase rotation direction. Thanks to the high class of ingress protection, IP64 the device can be used in heavily dusted and humid environments. Testers meet the requirements of CAT III 1000V / CAT IV 600V category. The DT-9231 model is equipped with a simple LED indicator showing the voltage level, whereas the more advanced model has a built-in backlit LCD. Additionally, the DT-9332 allows for measurement of resistance within the range of 0…1999 Ω. The built-in flashlight in both models facilitates work in poor external light conditions.

True-RMS DT-9560 multimeter
and design, will be perfect
for industrial applications.
Another new product available from TME is the True-RMS DT-9560 industrial multimeter. Its distinctive feature is high ingress protection rating, IP67, which means full protection against dust and water. The multimeter offers AC/DC resistance measurement within the range up to 1000V and AC/DC electrical power within the range from 600μA up to 10A, AC bandwidth from 45Hz up to 1kHz. Beside measuring such values as resistance, frequency or capacitance, it is possible to measure temperatures up to 1000°C with the use of K-type thermocouple. The built-in low-pass filter enables the analysis of signals from variable frequency drivers (VFD). A large, backlit display features a 61-level bar graph, while additional functions such as Data Hold, Min/Max boost its attractiveness.
