EX470A : 12 Function True RMS Professional MultiMeter + InfraRed Thermometer ยี่ห้อ Extech, USA
 |
True RMS, autoranging DMM with large digit LCD display and Type-K/IR temperature function
The Extech EX470A True RMS Multimeter and Infrared Thermometer with Capacitance, Frequency, and Duty Cycle Measurements and 2 K-Type Remote Probes is the perfect meter for HVAC or plant maintenance. The IR thermometer measures the surface temperature from -4 to 518 °F (-20 to 270 °C) without contact. The built-in laser pointer centers the measuring area. Multimeter functions include AC and DC Voltage to 600 Volt, AC and DC current to 10A, resistance to 40MOhm, continuity and diode test. Also includes Type K thermometer for contact or air temperature measurements from -4 to 1832 °F (-20 to 750 °C). Advanced functions include Capacitance, Frequency and Duty Cycle. The meter comes complete with test leads, Type K temperature probe, 9 Volt battery, protective holster, adjustable tilt stand and Velcro hanging strap.
Features:
- True RMS DMM with 12 functions and 0.3% basic accuracy
- AC/DC Voltage & Current, Resistance, Capacitance, Frequency, Type-K & IR Temperature, Diode/Continuity, Duty Cycle
- Built-in non-contact InfraRed Thermometer with 8:1 distance to target ratio with 0.95 fixed emissivity
