Digital Polarimeter BK-P850Pro ±89.99° Optical Rotation Peltier Temp. Control 8-Inch Touchscreen 8GB Storage (CAT#: STEM-LT-0953-ZJF)

The BK-P Series Polarimeters are high-precision optical instruments with advanced control features and large color touchscreens. Models with “A” offer automatic calibration via five standard points, and “Pro” models include an 8-inch display, 8GB storage, and Wi-Fi connectivity. BK-P850 models integrate Peltier temperature control (15–30°C, ±0.3°C) for stable measurement conditions. All models provide a wide measuring range of ±89.99° optical rotation or 259°Z, 0.001° readability, and 0.002° repeatability, making them suitable for research and industrial applications requiring exceptional accuracy.
