Ear Bars have laser-engraved scales, 50mm of calibration and are 6.2 mm square. New Standard and Lab Standard series Ear Bars have a different zero point than those for the 51800 series. Standard (18°) Ear Bars taper at the tip to penetrate far into the ear canal for a more secure hold. Non-puncture Ear Bars have a 45° taper and do not puncture the tympanic membrane.
