The Megger MTB7671 instrument test box is produced by Britain’s premier test instrument manufacturer. For that reason it tests your testers to the requirements of British Standards.
Nobody understands the requirements and intentions of the Standards better than Megger, so why waste your money on a lesser product?
Certification bodies like the NICEIC, ELECSA and others now request evidence of your tester’s accuracy and consistency.
The MTB7671 makes that an easy job.
You can test the insulation resistance, continuity, earth loop impedance, PFC, RCD and voltmeter functions of you testers quickly and easily, recording the test results on the record cards included in the pack. There are also self-adhesive test labels for your tester.
These Insulation Resistance Testers are the ideal instruments when high ranges are needed for measuring insulation resistance. Both provide excellent test voltage regulation and an external guard terminal to eliminate surface leakage current from the measurement.
The instruments are all electronic; they generate a regulated dc high voltage and use low-zero-drift, high-accuracy circuits, with high current sensitivity. Designed for portability, each is enclosed in a molded, impact-resistance, flame-retardant case.
No scale multipliers
Multiple test voltages for spot and step voltage testing
Guard terminal to eliminate surface leakage current
The MJ459 and MJ159 replace the BM12 and MJ10, respectively.
Four models are available for general purpose testing which include a low-voltage model.
