T-10A / T-10MA
The Konica Minolta T-10A (standard) and T-10MA (multi-point) are high-precision illuminance meters designed for measuring light levels (illuminance in lux) in a wide range of applications. The T-10A illuminance meter features a slim, lightweight receptor head with cosine-corrected diffuser for accurate illuminance measurement regardless of light incidence angle. The T-10MA variant supports up to 30 simultaneous measurement points using separate receptor heads, enabling illuminance mapping of large areas. Both models meet JIS C 1609-1:2006 AA-class and DIN 5032 Part 7 Class B requirements. The T-10A/T-10MA is used for workplace lighting compliance, architectural lighting design verification, roadway lighting assessment, sports facility lighting, and any application where precise illuminance data is required.

Measurement Principle of the T-10A Illuminance Meter
The T-10A receptor head contains a silicon photodiode with a V(λ) matching filter that approximates the human eye's spectral sensitivity. A cosine-corrected diffuser ensures that the measured illuminance is accurate regardless of the angle of light incidence. The instrument measures illuminance in lux (lumens per square meter) with high accuracy and wide dynamic range.
Applications of the T-10A / T-10MA
Workplace Safety
Occupational illuminance compliance testing — verifying that offices (300–500 lux), factories (200–750 lux), and warehouses meet regulatory requirements.
Architectural Lighting
Design verification and commissioning of lighting installations in commercial and public buildings.
Roadway and Outdoor Lighting
Luminance and illuminance assessment of roads, tunnels, parking lots, and sports facilities.
Photography and Film
Set lighting measurement for exposure determination and lighting balance.
Q: What is the difference between T-10A and T-10MA?
A: The T-10A has a single built-in receptor, while the T-10MA supports up to 30 separate receptor heads for simultaneous multi-point illuminance measurement and mapping.
Q: Can the T-10A measure LED lighting?
A: Yes, the T-10A's improved V(λ) filter provides accurate illuminance measurements for LED, fluorescent, and all other common light source types.
