EDUCATIONAL
LABORATORY PORTABLE DESK TOP METERS |
|
|
Laboratory Desk-top instruments are specially designed for easy to use in Schools, Colleges, Radio Shop, Laboratories and Factories. Mounted on insulated Moulded desk type stand with connection on top terminals. The instruments have clear acrylic front ; size 106 x 84 mm with knife edge pointer & an anti-parallax mirror dial. All meters are inclined at an angle of 450 for easy reading. Ranges on multi-range model are selected by connecting to appropriate terminals. These instruments are ideal for use as teaching models and for experiments.
