Reading Magnifier, 60mm, 10cm Focal Length, Alternate Model Capacity_3000mL dropping into the demonstration meter

dropping into the demonstration meter as a 0-1A AC ammeter for transformer and household-current measurements

sweat glands

providing a measurable stress-strain study on paired wire specimens

supplying precise low-resistance values for Wheatstone-bridge and Ohm's-law investigations

viewable between clear plates so students watch sprocket teeth grip and transfer torque under load

Reading Magnifier, 60mm, 10cm Focal Length, Alternate Model Capacity_3000mL dropping into the demonstration meterDrops the focal length to 10cm on a 60mm aperture in alternate model framing, the shorter focus delivering more magnification at the cost of field of view.
