BR Biochem PHS-25CW pH Meter: Precision Benchtop Acidity Tester for Laboratory
The BR Biochem PHS-25CW pH Meter is a classic, economical, and reliable benchtop pH meter designed for accurate pH and mV measurements in a variety of laboratory, educational, and industrial settings. This instrument combines ease of use with robust performance, making it an ideal choice for basic teaching, production enterprises, and daily testing and controls.
Overview
Equipped with a clear white backlit LCD display, the PHS-25CW provides an intuitive interface for displaying measured values and mode indicators. Its integrated plastic housing and keypad are sealed to protect against accidental spills, ensuring durability and longevity in a busy lab environment. The convenient holder arm can be rapidly switched to both sides, swiveling and articulating for optimal positioning during measurements.
Key Features
• High Accuracy Measurements: Benefit from precise readings with a pH measurement accuracy of ±0.05 pH and an mV measurement accuracy of ±10 mV. The meter covers a wide pH range from 0.00 to 14.00 pH.
• Intuitive 2-Point Calibration: The PHS-25CW features a simple 2-point push-button calibration system. It automatically recognises standard buffer solutions, supporting both USA (pH 4.01, 7.00, 10.01) and NIST (pH 4.01, 6.86, 9.18) standards, ensuring accurate calibration every time.
• Manual Temperature Compensation: To enhance accuracy under varying temperature conditions, the meter includes manual temperature compensation over a range of 0 to 100°C. This allows users to input the sample temperature for optimal measurement results.
• Electrode Diagnostics: An automatic electrode slope display feature provides valuable feedback, helping users determine when a pH electrode may need to be replaced, thus ensuring consistent performance.
• User-Friendly Operation: The meter's succinct membrane keypad with clearly labelled functions and symbols makes it straightforward to operate, facilitating quick and efficient measurements.
Versatile Applications
The PHS-25CW pH Meter is suitable for a broad spectrum of applications, including:
• General laboratory pH and mV value determination.
• Educational purposes and teaching applications.
• Quality control in production enterprises.
• Measurement of water-based paints and viscous samples (when used with an appropriate pH electrode like the P11).
• Applications requiring compliance with standards such as GB/T13531.1, JJF 1575-2016, JJG 2060-2014, and specific industrial tests like those for silica-alumina carbon black, textiles, and leather.
Included Accessories
The standard package for the BR Biochem PHS-25CW pH Meter includes:
• The PHS-25CW Host Meter
• E201-BNC pH electrode
• pH standard buffer reagents (pH 4.01, 6.86, 9.18)
• DC9V Power Adapter
• User Manual
