Tesca Portable Indicating (Pointer) Type Meter is designed for continuously traceable measurement of frequency in laboratories, research rooms, schools, production lines, etc. One of the specialties in the design of this instrument is the application of a frequency-to-DC current transducer to a high-sensitivity moving coil-type indicator. Accurate, quick, frequency measurements are attained with this instrument without any noticeable influence of line voltage fluctuation or waveform distortion. The legible wide scale is perfectly uniformly graduated.

Features:

• Knife edge Pointer & Anti-parallax mirror scale.
• Tough Bakelite Case: The complete body of the instrument is made from a superior grade of bakelite. The unique design makes it very strong in construction and at the same time provides very high insulation.
• Shock-resistant Pivot jewel movements: The pivots are made from Carbon Steel hard chrome plated and are mounted in spring-loaded sapphire jewels. This ensures shock resistance due to vibrations in transit and minimum friction during use.
• Dust Proof: The movement is placed in a separate compartment making it completely dustproof, thus ensuring a long life and years of trouble-free service.
• Quick Response due to unique damping.
• Confirming to BS 89, IEC 51 & ISS 1248.
