The M1 Wave wireless bore gage with an optional inductive battery charger is equipped with a Li-ion battery pack that features a minimized memory effect, providing continuous use without any need for battery replacement. A fully recharged gage provides approximately 36 to 40 hours of use. When full recharging time of five to six hours is not possible, the gage may be used in cycle measure and charge mode (one measure, one refill shot while waiting for the next workpiece), thus enabling the gage to be used on a 24/7 basis. The gage uses Bluetooth wireless technology to transmit data to the receiving electronic unit, and incorporates IP67 contactless recharging technology. The inductive rechargeable feature is easy to apply and may be retrofitted to the company’s existing gages that use alkaline batteries for operation.
