Extech Instruments 380400 Resistance Box

Resistance, capacitance, and inductance decade boxes are designed with heavy-duty, durable enclosures suitable for product development and calibration testing. They feature a grounded case, three binding posts for isolated substitutions, and offer 1% resistance accuracy from 1 ohm to over 11 million ohms across seven resistance ranges. Values can be adjusted in 1-ohm increments, utilizing 0.3-watt resistors with internal zero resistance for precise measurements. Ideal for test and measurement, maintenance, and repair applications.
