Need help?Do you have a question about the fristadenlab PHS-3C and is the answer not in the manual?
The Fristaden Lab Digital pH Meter, Model PHS-3C, is a laboratory instrument designed for accurate measurement of pH and mV values. This user-friendly device offers a range of features for various applications, from basic pH testing to more complex calibration procedures.
The primary function of the PHS-3C is to measure the pH of solutions, indicating their acidity or alkalinity. It also has the capability to measure mV, which can be useful for ORP (Oxidation-Reduction Potential) measurements when an ORP electrode is connected. The meter features a clear LCD display that shows the measured pH or mV value, temperature, and various operational indicators such as "STORE," "MAX," "MIN," "RECALL," and "ATC" (Automatic Temperature Compensation) or "MTC" (Manual Temperature Control).
The device supports both single-point and slope calibration, allowing for precise adjustments to ensure measurement accuracy. It can store and recall maximum and minimum values, which is beneficial for monitoring changes over time or for quality control purposes. The temperature compensation feature, either automatic or manual, ensures that pH readings are accurate regardless of the sample's temperature.
The device's high input resistance ensures minimal current draw from the pH electrode, contributing to stable and accurate readings. Its stability specification indicates that readings will drift by no more than ±0.01 pH over a 3-hour period, highlighting its reliability for extended measurements. The inclusion of pH buffer powders for 4.01, 7.00, and 10.01 pH values facilitates multi-point calibration, which is crucial for achieving high accuracy across the entire pH range.
The PHS-3C is designed for straightforward operation.
Installation: The setup process involves placing the pH meter on a flat surface, connecting the electrode arm, plugging in the pH electrode, attaching the power cord, and turning on the device. Calibration: The meter supports both single-point and slope calibration. For single-point calibration, the device is calibrated to pH 7.00 using deionized water. For slope calibration, multiple buffer solutions (pH 4.01, 7.00, and 10.01) are used to establish a more accurate calibration curve. The manual emphasizes the importance of proper calibration for accurate results. Temperature Control: The device supports both Manual Temperature Control (MTC) and Automatic Temperature Compensation (ATC). For MTC, the user manually inputs the temperature. For ATC, a temperature probe (if available) automatically adjusts readings based on the sample temperature. pH Sample Testing: To test a sample, the electrode is rinsed, placed in the sample solution, and the display is allowed to stabilize before recording the measurement. MAX/MIN Function: This feature allows users to record and view the maximum and minimum pH or mV values measured over a period, useful for monitoring fluctuations. Storage/Recall Function: The meter can store up to 25 measurement values, which can be recalled later for review.
Proper maintenance is essential for the longevity and accuracy of the pH meter and its electrode.
The manual also provides important safety warnings, particularly regarding pH buffer powders, which can cause eye or skin irritation if not handled properly. Users are advised to seek professional medical assistance if contact occurs. It also highlights general safety practices such as operating the machine in a safe environment, keeping it away from magnetic parts, and checking for damage before use.
The Fristaden Lab Digital pH Meter is a robust and reliable instrument suitable for a wide range of laboratory and industrial applications, backed by a 1-year manufacturer's warranty and customer support.
