Bante 901 Benchtop Multiparameter pH/Conductivity Meter
The Bante 901 is a high-performance laboratory benchtop meter designed for comprehensive water quality analysis. By combining high-precision pH measurement (±0.002 pH accuracy) with professional Conductivity and TDS capabilities, it serves as a complete solution for checking the chemical and physical properties of aqueous samples.
Equipped with a large backlit LCD and an intuitive button layout, the 901 is ideal for university laboratories, quality control testing, and wastewater analysis where both acidity and ionic content must be verified simultaneously. While primarily a pH/Conductivity meter, it also supports ORP (Oxidation-Reduction Potential) measurements via its mV mode. Key Features
High-Accuracy pH & ORP
- 5-Point Calibration: Supports up to 5 calibration points with auto-buffer recognition (USA, NIST, DIN, and User-defined standards).
- Precision: Delivers research-grade accuracy of ±0.002 pH.
- ORP Capable: Measures absolute millivolts (mV) for Redox potential analysis (requires separate ORP electrode).
- Electrode Diagnostics: Automatic slope and offset display helps you track sensor health.
Professional Conductivity & TDS
- Wide Range: Measures from pure water (0.01 µS/cm) up to saturated solutions (200 mS/cm).
- Linear & Pure Water Compensation: Selectable temperature coefficients ensure accuracy across all sample types, including ultrapure water.
- Adjustable Cell Constants: Compatible with K=0.1, 1.0, and 10.0 electrodes to match your specific measurement range.
General Features
- Automatic Temperature Compensation (ATC): Included temperature probe ensures all readings are corrected to 25°C.
- Calibration Due Alarm: Programmable reminder (1 to 31 days) ensures you never miss a scheduled calibration.
- Data Management: Stores up to 500 data sets with GLP-compliant time/date stamping.
- Connectivity: USB interface for easy data transfer to a PC (DAS software enabled).

Expert Tip: Who needs the 901?
If you currently use two separate meters—one for pH and one for Conductivity—the Bante 901 consolidates your bench space and workflow into a single, highly accurate device. It is superior to handhelds for stationary lab work due to its larger display, higher stability, and data logging capacity.
