New Yokogawa Big Look Panel Meters feature extra-wide scales, big bold numerals above the scale and divisions for unobstructed reading. Tapered needle-sharp pointers and shadow-free acrylic covers help to pinpoint values. Available in taut band and pivot and jewel types. Gasket sealer gives New Big Look dust and moisture resistant design. (Except 1 1⁄2").

Dust Resistant Construction.
YOKOGAWA Big Look panel meters, except 1-1/2”, feature gasketed construction to seal out dust and other air-suspended damaging particles. Application is ideal for adverse environments. Special dust resistant features are included on all YOKOGAWA New Big Look meters (except 1-1/2”). For more severe applications, to meet UL-1437 or IEC 144 requirements, other models are also available upon request.

Clean, Readable Case Design Provides Extra Safety:
YOKOGAWA’s brand New Big Look and Horizon Line panel meters are designed to provide attractive styling, quick, sure readability for any application, and a built in safety feature to help you meet national safety requirements. If you must remove the acrylic cover, you have to remove the instrument itself from the panel in order to reach the special safety screws holding on the cover. Removing the meter prevents shock hazard. This safety feature is standard on all New Big Look and Horizon Line meters.

Gasket Sealing Design Establishes A New Industry Standard:
Dust resistant construction is now a standard feature of all New Big Look panel meters 2-1/2” - 4-1/2” only. YOKOGAWA's unique gasket sealing design eliminates the need for a crimped bezel, providing for quick modification and scale changes while maintaining the integrity of the meters.

Pivot and Jewel:
In this design the coil and pointer are supported by polished steel pivots at each end which fit into jewel bearings. Pivot and jewel meters are recommended for high vibration environments because of the mechanism’s inherent stability and strength. Accuracy and repeatability are almost equal to the taut-band’s, and good performance from the pivot and jewel construction is the reason for its long popularity. Don’t specify pivot and jewel meters for applications that involve high shock, but do take advantage of this meter’s ability to withstand vibration.

Conduit Mounting Case — 2-1/2-inch New Big Look Meter:
Available only for 2-1/2-inch Type 250 panel meters, for indoor or outdoor use, the conduit mounted case provides protection to the meter under severe environmental conditions. The conduit case is both sealed and weatherproof and is pre-drilled, ready for mounting of separately ordered panel meters. Assembly of meter into case is done by purchaser. (Drawing No. 2579K10700.)
