Reference Thermometers
Reference thermometers (standard thermometers) are, due to their excellent stability and their geometrical adaptations, ideally suited for applications in industrial laboratories. They enable easy comparative calibration in baths, in tube furnaces and in dry-well calibrators. The advantage of reference thermometers is the wide temperature range, and with this, their flexible operation. Furthermore, with their low drift, a long service life is ensured.

TEV Antenna
TEV sensor is a partial discharge sensor whose working principle is based on a direct Capacitive coupling with a Switchgears earthed metal case. The two ends of TEV sensor can be coupled magnetically to virtually any opening on a metal Surface. It picks up the electric signal given by PD activity onto the two metallic surfaces. Thanks to its special design has high sensitivity, larger than other single ended TEV sensors. His compact and robust design (passive sensor) makes the TEV the optimal sensor for direct installation on medium voltage Switchgears.

Omnidirectional Antennas
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis.[1][2] When graphed in three dimensions (see graph) this radiation pattern is often described as doughnut-shaped. Note that this is different from an isotropic antenna, which radiates equal power in all directions, having a spherical radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted. Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS, as well as for base stations that communicate with mobile radios, such as police and taxi dispatchers and aircraft communications.
