Add With the rapid development in industries of lithium batteries, smart phones and hybrid vehicles, battery manufacturers have a great need in high-efficiency and high-reliability insulation testing. Tessio Instrument provides 3 models digital Insulation Resistance Meters to meet this demand.

TR-3920 high-speed Insulation Resistance Lithium Tester is designed to fast-sorting insulation resistance (IR) value less than 10GΩ of components and equipment. Using the constant voltage test method, its voltage output range is 25~1000V and the maximum output current is 1.8mA. TR-3920 has contact abnormality detection function to prevent misjudgment in case of poor contact, the minimum test period is only 50Ms, which achieves the fastest speed in the industry and greatly shorten inspection time in production line sorting of electronic components.

TR-2683 high-insulation Resistance Tester, LCD display dual test function, resistance/leakage current in one instrument, measuring the insulation properties of electronic components and components (especially capacitance), dielectrics, materials, devices, wires, cables, etc. and also has a sorting output and external single pulse signal input interface, making it easy for pipeline operation. The instrument has a powerful anti-interference ability, which makes the measurement more reliable.

TR-3930 Insulation Resistance Tester is suitable for ultra-high resistance testing (up to 9.9PΩ) and ultra-low current(low to 10fA) testing.

With the support the matching electrode box, the surface resistance and volume resistivity of various insulating materials can be accurately measured. Widely used in the field of insulation performance evaluation of insulation materials.

Equipped with rich interfaces and communication ports like LAN, RS232 port, I/O port (PLC interface), analog signal output and test ports at the rear panel, TR-3920 is convenient for system integrators.
