Sealey TM103 Professional Auto Ranging 11 Function Digital Multimeter

The Sealey TM103 is a professional-grade auto-ranging digital multimeter designed for accurate electrical testing and diagnos... moretics across a wide range of applications. This 11-function instrument delivers high precision measurements whilst conforming to EN 61010-1 CATIII 600V safety requirements, making it suitable for electricians, maintenance engineers and automotive technicians working with both low and high voltage systems. The auto-ranging function automatically selects the appropriate measurement range, streamlining workflow and reducing user error during complex diagnostic tasks. The large digital display features 2.1 x 24.5mm digits for clear visibility in various lighting conditions, whilst the double-moulded housing with soft grip case provides durability and comfort during extended use. Practical design features include integrated probe and lead storage, an upright stand for hands-free workbench operation, and data-hold functionality for recording measurements. This versatile multimeter measures AC and DC voltage up to 600V, AC and DC current up to 10A, resistance up to 40MO, capacitance up to 100µF, frequency from 9.999Hz to 9.999MHz, and duty cycle from 0.1% to 99.9%. Temperature measurement capability extends from -20°C to 760°C, making it ideal for HVAC diagnostics and automotive applications. Additional functions include audible continuity testing and diode testing for circuit verification work. The auto-power-off feature conserves battery life, whilst the low battery indicator ensures you're never caught without power during critical testing. Supplied complete with a zipped carry pouch with strap for secure transportation between job sites. Features and Benefits: • Auto-ranging functionality eliminates manual range selection for faster, error-free testing • CATIII 600V safety rating ensures protection when working with mains electrical systems • Temperature measurement from -20°C to 760°C for HVAC and automotive diagnostics • Data-hold function allows measurements to be locked for recording • Integrated probe storage and upright stand for organised workbench use • Compact design (150 x 70 x 48mm) fits easily into toolboxes and pouches Specifications: Brand: Sealey Nett Weight: 255g AC Voltage (Accuracy): 400mV (±1.5%), 4V (±1.2%), 40V, 400V (±1.5%), 600V (±2%) DC Voltage (Accuracy): 0-400mV (±0.5%), 4V, 40V, 400V (±1.2%), 600V (±1.5%) AC Current (Accuracy): 400µA (±1.5%), 4000µA, 40mA, 400mA (±1.8%), 10A (±3%) DC Current (Accuracy): 400µa (±1%), 4000µa, 40mA, 400mA (±1.5%), 10A (±2.5%) Resistance (Accuracy): 0-400O (±1.2%), 4kO (±1%), 40kO, 400kO, 4MO (±1.2%), 40MO (±2%) Capacitance (Accuracy): 4nF, 40nF (±5%), 400nF, 4µF, 40µF (±3%), 100µF (±5%) Temperature (Accuracy): -20ºC to 760ºC (±3%), -4 to 1400ºF (±5%) Frequency (Accuracy): 9.999Hz to 9.999MHz Duty Cycle: 0.1%-99.9% (±1.2%) Continuity Audible: Yes Diode Test: Yes Transistor Test: No Hi-Impact Rubber Case:
