2019 BTS256-PAR

Product catalog summary

Overview: The BTS256-PAR is a sophisticated light meter designed for measuring photosynthetically active radiation (PAR), illuminance, luminous color, and other photometric and colorimetric parameters. It is equipped with a BiTec light sensor that combines a silicon photodiode and a CMOS diode array for precise measurements.

Key Features:

BiTec Light Sensor: Combines silicon photodiode and CMOS diode array for accurate photometric and spectral-radiometric measurements.
User-Specific Weighting Functions: Allows up to five custom weighting functions for tailored calculations.
Cosine Corrected Field of View: Ensures measurement accuracy with a diffuser window that meets DIN 5036 quality class B standards.
DIN Quality Class: Meets DIN 5032 quality class A and B standards for various photometric parameters.
Display Modes: Offers standard and customizable display modes for various measurement needs.
Data Logging: Features fast data logger modes for recording photodiode and spectral data.
PC Connectivity: USB 2.0 interface for data exchange and battery charging, with optional WiFi connectivity.

Specifications:

Sensor: Bi-Technology sensor with photometric broadband detector and array spectrometer.
Input Optics: 20mm diameter diffuser window with cosine correction.
Calibration Uncertainty: Illuminance +/-2.2%, spectral irradiance varies by wavelength.
Spectral Range: 380 - 750 nm with 10 nm optical bandwidth.
Measurement Range: Up to 199,999 lx for illuminance, 0.1 - 20000 µmol/(m²s) for PAR.
Power Supply: 5VDC via USB, with rechargeable battery for over 8 hours of operation.
Dimensions and Weight: 159mm x 85mm x 45mm, 500g.

meets the conditions specified for two of the DIN 5036 quality classes. • In terms of the f2 uncertainty i.e. < 3%, the device corresponds to the quality class B (DIN 5032 section 7). • In applications where limitation of the viewing angle is acceptable, the BTS256-PAR, with its f1', u, f3 and f4 values, corresponds to the quality class A (DIN 5032 section 7). Diverse photometric and colorimetric measurands A much broader diversity of measurands as the one offered by conventional light meters is required for verification and testing of LED lamps. The BTS256-PAR offers fourteen measurands and...
