TEGAM offers rugged micro-ohmmeter Kelvin probes
October 13, 2014. TEGAM Inc., a supplier of micro-ohmmeters, has just introduced five new Kelvin probes. When used with TEGAM's R1L bond meters or the 1740 or 1750 micro-ohmeters, they enable engineers and technicians to more easily make four-wire bonding and other low-resistance measurements.
The BKP-10 Kelvin probes are designed for heavy-duty applications where engineers must make four-wire surface resistance measurements on bonds and other metallic surfaces. Pin-to-pin spacing is 0.19-in. (4.8 mm), and the probe can be ordered with three types of pins, including a spear point pin, a flat point pin for making surface resistance measurements, and a serrated pin when a coating must be pierced. The test leads are ten feet long and terminated with dual banana plugs on 0.75-in. spacing for use with the R1L bond meters.
The MKP-6 and MKP-1750/5 Kelvin probes are designed for making four-wire surface resistance measurements in tighter spaces. Pin-to-pin spacing is 0.11 in. (2.8 mm), ensuring an operator error-free measurement. These probes can be ordered with five types of pins, including a spear point pin, a flat point pin, a serrated pin, a spherical point pin, and a rotating pin. The test leads of the MKP-6 are ten feet long and terminated with dual banana plugs on 0.75-in. spacing for use with the R1L bond meters. The test leads of the MKP-1750/5 are five feet long and terminated with a connector compatible with the TEGAM 1740 and 1750 micro-ohmmeters.
The MCP-6 and MCP-1750/5 Kelvin probes are designed for making four-wire surface resistance measurements where space is at a premium. These probes use a unique coaxial pin with a 0.63-in. diameter that allows four-wire resistance measurements in very tight spaces. The test leads of the MCP-6 are ten feet long and terminated with dual banana plugs on 0.75-in. spacing for use with the R1L bond meters. The test leads of the MCP-1750/5 are five feet long and terminated with a connector compatible with the TEGAM 1740 and 1750 micro-ohmmeters.
According to Andy Brush, TEGAM CEO, no other company makes a hand-held probe with such a small pin. “These probes enable four-wire measurements in places inaccessible with other probes,” he said.
Another unique feature is their ergonomics. “We designed the probe to minimize hand fatigue in bench and field service applications,” Brush said.
