MAS830 Series & HY8233 Series Digital Multimeters
The MAS830 (green/black) and HY8233 (orange/black) series digital multimeters deliver reliable electrical testing. Both feature 2000-count displays, backlit screens, data hold, continuity tests, and max value hold. MAS830 measures DC/AC voltage (up to 600V), DC current (20mA–20mA), and resistance (200Ω–20KΩ) with ±0.8%–±3.0% accuracy. HY8233 adds frequency (20Hz–2000Hz) and temperature (-20℃–1000℃) measurement, auto power-off, and overload protection. Compact (145×74×44mm/148×74×42mm), lightweight (~186g/~174g), and 9V battery-powered, they suit professionals and DIYers.
Product Details
The MAS830 Series and HY8233 Series Digital Multimeters are compact, user-friendly tools designed for precise electrical diagnostics. Both models combine essential measurement functions with durable construction, making them ideal for electricians, technicians, and electronics enthusiasts.
Design & Display:
MAS830: Green/black casing with a central digital display, rotary dial for selecting DC/AC voltage, DC current, resistance, and special functions. Three input jacks (10ADC, COM, VΩmA) enable safe connections.
HY8233: Orange/black design featuring a prominent "HY8233" branding, 6000-count display (showing sample reading "6000"), and a rotary dial with expanded options (voltage, current, resistance, frequency, temperature). Input jacks include COM, 10A, and VΩmA.
Technical Specifications:
Voltage:
MAS830: DC (200mV/2V/20V/200V/600V, ±0.8% reading + 3 digits), AC (200V/600V, ±1.2% reading + 10 digits).
HY8233: DC (200V/600V, ±0.8% reading), AC (200V/600V, ±1.2% reading).
Current:
MAS830: DC (20μA/200μA/20mA, ±3.0% reading + 10 digits).
HY8233: DC (200mA, ±1.5% reading), AC (200mA, ±1.0% reading).
Resistance: Both series cover 200Ω–20KΩ/200KΩ (±0.1%–±1.0% error + 5 digits).
Extended Functions:
HY8233adds frequency (20Hz–2000Hz) and temperature (-20℃–1000℃, ±10℃/±10% accuracy).
Key Features:
Both models include a 2000-count display, backlit screen for low-light use, data hold to freeze readings, continuity test (audible beep for circuits), and max value hold for tracking peak measurements. HY8233 enhances usability with auto power-off (battery conservation) and overload protection (prevents damage from excess input).
Basic Parameters:
Power: 1×9V battery (6F22 type).
Weight: MAS830 (~186g), HY8233 (~174g).
Dimensions: MAS830 (145×74×44mm), HY8233 (148×74×42mm).
Packaging: MAS830 (standard carton), HY8233 (40 units/carton).
Applications:
Ideal for circuit troubleshooting, appliance maintenance, and educational experiments. The MAS830’s simplicity suits basic tasks, while HY8233’s extended functions (frequency/temperature) cater to advanced diagnostics. Their portability allows fieldwork in industrial, residential, or lab settings.
Advantages:
Accuracy: Tight tolerances (±0.8%–±3.0%) ensure reliable results.
Durability: Rugged casings withstand daily use.
Ease of Use: Intuitive dials and clear displays reduce learning curves.
