P3000 is intended for standard polarimetry where ±0.01° accuracy is sufficient. It displays optical rotation or the ICUMSA international sugar scale within 1–2 seconds and can convert values to 20 °C.
Advantages
Digital measurement and scales
- Automatic optical-rotation (°) and international-sugar (°Z) measurements; accuracies ±0.01° and ±0.01 °Z.
- Measurement period 1–2 seconds after temperature equalisation and at sample OD < 1; sample transmittance >0.1% (OD 3).
- 589 nm measuring wavelength; sample chamber accepts tubes up to 220 mm.
Operation, adjustment and result output
- 3.5-inch capacitive touchscreen and keypad; automatic menu-guided adjustment.
- RS-232 for a serial ASCII printer; methods and user management are not available.
- Quartz control plates can be used for verification and adjustment; purchase separately.
Temperature compensation and control options
- Pre-installed ICUMSA temperature compensation converts readings to 20 °C.
- Sample temperature control can be retrofitted with an external circulation thermostat and suitable temperature-controlled tube; unlike P9000, it is not integrated Peltier control.
- Optional stainless-steel or PTFE-coated sensors measure sample temperature.

Service support
- Experienced specialists provide product selection, application and operation support.
- Calibration, maintenance and maintenance contracts can be discussed as required.
Selection guidance
For standard tasks without complex method and user management. Confirm accuracy, sample transmittance, tube length, temperature compensation, external temperature control and printing.
Note: measurement period is specified after sample temperature equalisation and at OD < 1. Choose control equipment and tube material for the sample and method.
