The Cole-Parmer WD-35433-02 is a versatile multiparameter meter designed for comprehensive water quality testing. It measures conductivity, resistivity, salinity, TDS, dissolved oxygen, and temperature, with automatic barometric pressure compensation for accurate DO readings. This instrument is essential for environmental monitoring, wastewater treatment, and industrial process control.
Key Features & Highlights
- Multiparameter Measurement: Conductivity (0 to 500 mS), resistivity (0 to 20.00 MΩ), salinity (0 to 80 ppt), TDS (0 to 500 ppt), dissolved oxygen (0 to 600% or 0 to 90 mg/L), and temperature (14 to 230°F / -10 to 110°C).
- High Accuracy: ±1% full-scale for conductivity, resistivity, salinity, and TDS; ±2% or ±0.2 mg/L for DO; ±0.9°F (±0.5°C) for temperature.
- Data Integrity: Stores up to 500 data sets with time-and-date stamps for GLP compliance. Programmable calibration due dates ensure data reliability.
- Wireless Data Transfer: IrDA port allows wireless download of data to a PC or compatible device.
- Automatic or Manual Calibration: Single or multipoint standard recognition with programmable calibration due alarm.
- Temperature Compensation: Automatic or manual, 0 to 100°C, with linear or pure water modes for conductivity.
- Waterproof and Durable: IP67-rated waterproof design suitable for field use.
- Backlit Display: Dot-matrix LCD with backlighting for easy reading in low-light conditions.
