Product Description
The TPI 287 is a professional-grade True RMS digital clamp meter designed for aviation maintenance, HVAC/R technicians, and industrial electricians who need reliable, Bluetooth-enabled electrical measurements. Featuring a 6000-count dual backlit LCD and autoranging across AC/DC current to 1000A, AC voltage to 750V, and DC voltage to 1000V, the 287 delivers accurate readings in complex non-sinusoidal aircraft electrical systems where average-responding meters fall short. The slim-jaw design with a 33 mm jaw opening fits into tight avionics bays and engine compartments. In-Rush Current capture records motor startup current spikes that standard measurements miss — invaluable for diagnosing aircraft starter motors, actuators, and avionics power loads. Non-Contact Voltage (NCV) detection provides a safety check on live aircraft wiring harnesses. Bluetooth connectivity pairs with the free TPI View App (iOS and Android) to log live readings, create GPS-tagged test reports, and email results from a safe distance. The meter also measures resistance, capacitance, frequency with duty cycle, temperature via K-type probe, and DC microamps. CAT III 600V / CAT IV 300V safety rating meets IEC 61010 standards for professional aviation maintenance.
