Multimeters
A collection page of circuitrocks
About
Measure with confidence—voltage, current, resistance, continuity, capacitance, frequency, duty cycle, temperature, and more. This collection features true-RMS digital multimeters (DMMs) , AC/DC clamp meters , and essential accessories for repair, prototyping, and classroom labs in the Philippines. Perfect for Arduino , ESP32 , and Raspberry Pi projects. Shop by Type True-RMS DMMs – accurate on non-sinusoidal waveforms Auto-range DMMs – faster, fewer manual range errors Clamp meters (AC/DC) – measure current without breaking the circuit Bench multimeters – stable readings for testing and calibration NCV voltage testers – quick live-wire checks Top Accessories Silicone test leads & gold-plated probe tips Banana-to-alligator clip leads & mini hook clips K-type thermocouples (temperature) 10A/11A HRC fuses (replacement safety fuses) Carrying cases & 9V / AA/AAA batteries Buying Guide Safety first: Check CAT II/III/IV rating and max voltage. Use HRC fuses for high-current ranges. Accuracy & counts: 6000/9999/20000-count DMMs give finer resolution for small changes. True-RMS: Needed for variable-speed drives, switching supplies, and non-sine loads. Features: Auto-range, backlight, data hold, relative/zero, min/max, temperature, continuity beeper. Leads matter: Soft silicone leads bend better and resist heat; upgrade tips for precision work. Usage & Safety Tips Select the correct function and range before probing; start on higher ranges when unsure. For current, move the red lead to the current jack and break the circuit (or use a clamp meter). De-energize when changing probe positions; never measure resistance on a live circuit. Replace blown fuses with the exact HRC type and rating specified by your meter.
