Tessio Technology has complete resistance test solutions for various application requiring high-speed or high-accuracy testing integrated to automatic production line, R&D bench top use and portable tester for large equipment to test resistance of motor, cable, grounding, PCB and materials. Such as TR-3545/3542/2301 series resistance tester fit for fast and accurate, TR-3540 resistance meter quite suitable to measure super-low material resistance, TR-3544 resistance tester specially used in measuring strong anti-interference and anti-shock occasions (e.g.: motor and coil resistance test), for hand carry purpose are TR-3548 handheld resistance tester designed for on-site resistance testing and TR-3710/3720 Portable resistance tester designed for on-site to testing high current up to 10A/20A.
TR-2301/TR-3545/TR-3542 Precision DC Resistance Tester is one of the highest-precision DC resistance testers in the industry with 6 1/2 and 0.01μΩ mini. resolution. At full scale measurement range, TR-3545 has 1200000 digits display and TR-3542 has 120000. Both are ideally suited in the inverter motor coil inspection and other fields requiring high-resolution resistance measurement.
TR-2600/TR-3542 multi-channel resistance tester is special for measurement of three-phase motor coil; inspection of connectors and wiring harness; inspection of relay contacts; inspection of welded parts of battery terminals.
TR-2305/TR-3544 resistance tester is specially used for three-phase motor coil measurement, connector and harness inspection, relay contact inspection, and battery terminal weldment inspection. It is featured in its strong anti-interference and anti-surge performance.
The unique TR-3540B resistance tester specially used for the resistance measurement of conductive materials in the power industry, with minimum resolution 0.01μΩ, and accuracy <0.02% at full-range. Using the pulse test method, the current ratio is adjustable at 0.7 / 1.0 / 1.414, which can replace the traditional Wheatstone bridge for high precision measurement of ultra-low resistance.
TR-3548/TR-3710/TR-3720 Handheld & Portable Resistance Tester offers a portable solution for measuring resistance with a wide range 0.1μΩ~3.3MΩ at a high level of precision 0.02%. It has a wide application in measurement of ordinary resistors, coil resistance (large motors, transformers, and inductors), cable length and diameter detection, pipe welding and metals detection and electric cars to ground connection detection and so on.
Due to the strong surge withstand capability, TR-3548/TR-3710/TR-3720 portable resistance meter is designed to test winding resistance of devices.
