The Atomfair-APD-732 Photodiode Characteristic Experimental Instrument must be operated within specified environmental and power supply conditions to ensure accurate measurements and prevent damage. The instrument requires AC220V ±5%, 50Hz ±5% mains power and an ambient temperature of 0°C to 40°C with relative humidity ≤80%.
- Power Supply Requirement: Connect the instrument to an AC220V ±5%, 50Hz ±5% mains supply only.
- Ambient Temperature Range: Operate the instrument within an ambient temperature range of 0°C to 40°C.
- Humidity Limit: Maintain relative humidity at or below 80% during operation.
How does the illuminance meter accuracy vary across different measurement ranges for the Atomfair-APD-732?
The built-in high-precision illuminance meter offers a measurement accuracy of ±10%rdg ±10dts at 10,000 lx when calibrated under 2856K white light, with a linearity of +2%. It supports four freely switchable ranges (200 lx, 2000 lx, 20000 lx, and 50000 lx) and a resolution of 0.1 lx, enabling precise irradiance measurements across diverse photodiode characterization experiments.
Can the Atomfair-APD-732 be used to analyze photodiodes operating at different wavelengths, and what light sources are included?
Yes, the instrument includes a multi-band light source system covering seven professional sources: white light (1000-2500 mcd), red (625-630 nm), orange (600-605 nm), yellow (585-590 nm), green (515-520 nm), blue (460-465 nm), and violet (400-405 nm). This allows comprehensive spectral characteristic testing of photodiodes across the visible spectrum.
What are the operating temperature and humidity requirements for the Atomfair-APD-732 instrument?
The Atomfair-APD-732 operates reliably in temperatures from 0 °C to 40 °C and humidity levels ≤80%. It requires a power supply of AC220 V ±5% at 50 Hz ±5%. The host measures 514 mm × 314 mm × 140 mm and weighs ≤4 kg, making it suitable for bench-top use in standard laboratory environments.
The Atomfair-APD-732 integrates a precision host, seven-band light source, and high-resolution illuminance meter into a single benchtop instrument, enabling comprehensive photodiode characterization including dark current, spectral response, and time-response measurements with 0.2% voltmeter/ammeter accuracy.
Positive
- Integrated multi-band light source: Seven discrete LED wavelengths (400-630 nm) plus white light enable spectral response characterization without external monochromators or filter wheels, simplifying experimental setup and reducing alignment errors.
- High-accuracy electrical measurement: Voltmeter and ammeter both offer 0.2% accuracy across four switchable ranges (200mV-200V; 200µA-200mA), providing reliable quantitative data for volt-ampere and photocurrent analysis in research and QC applications.
Trade-offs
- Mains power dependency: Requires AC220V ±5%, 50Hz ±5% supply, limiting portability and necessitating stable laboratory power infrastructure; operation outside this range may affect measurement accuracy.
- Environmental sensitivity: Specified for 0-40°C and ≤80% humidity, so high-humidity or temperature-extreme environments can degrade photodiode dark current measurements and illuminance meter linearity, requiring controlled lab conditions.
