Eutech PH TUTOR-L pH Meter: Precision for Professional Measurement
The Eutech PH TUTOR-L is an advanced, microprocessor-based benchtop pH meter designed for accurate and reliable measurement of pH, mV (ORP), and temperature across a wide spectrum of applications. This user-friendly instrument is an ideal choice for laboratories, educational institutions, research facilities, and various industrial settings where precise pH monitoring is crucial.
The meter operates by detecting the electrical potential difference between a pH electrode and a reference electrode, translating this into clear insights regarding a solution's acidity or alkalinity. Its robust design ensures durability, while its comprehensive features make it a versatile tool for diverse testing needs.
Key Features
• High Accuracy & Wide Measurement Range: Capable of measuring pH from 0.00 to 14.00, along with mV (ORP) from 0 to ±1999mV, providing highly accurate and repeatable results.
• Exceptional Resolution: Offers a fine resolution of 0.01 pH, 0.1 mV, and 0.1 °C for detailed and precise readings.
• Smart Calibration & Buffer Recognition: Features easy push-button calibration with up to 3 points and automatic recognition of standard buffer solutions, simplifying the calibration process. It supports US Standards (pH 4.01, 7.00, 10.01) and NIST Standards (pH 4.01, 6.86, 9.18).
• Automatic Temperature Compensation (ATC): Ensures reliable measurements across varying sample conditions with an automatic or manual temperature compensation range of 0 to 100 °C.
• User-Friendly Display: Equipped with a large, easy-to-read custom dual-line LCD display that shows both pH and temperature values simultaneously.
• Self-Diagnostic Features: Includes a stability indicator, pH slope and offset display, and self-diagnostic messages for enhanced reliability and troubleshooting.
• Comprehensive Kit: Supplied ready-to-use with a pH meter, a plastic-body "3-in-1" pH/Temperature combination electrode (featuring a BNC connector and 1-meter cable), an integrated electrode stand, and a power adapter. Some variants also include standard buffer solutions.

Maintenance Tips for Optimal Performance
To ensure the longest possible life and accurate performance from your pH meter, proper care is essential:
• Electrode Storage: If the electrode is delivered dry, soak it for at least 2 hours in a preservative solution or water. The protective cap can be filled with this solution to keep the electrode operational longer.
• Calibration: Always calibrate the pH meter before use with fresh buffer solutions. If your meter supports single-point calibration, use a buffer solution closest to your expected measurement range.
• Avoid Contamination: Do not introduce contaminants into buffer solutions. Always rinse the electrode with distilled water before and after each measurement and gently dry it with a soft, lint-free cloth. Avoid touching the electrode bulb to prevent static electricity interference.
• Temperature Consistency: Ensure the buffer solution and sample temperatures are consistent. Use temperature compensation if there's a difference.
• Regular Checks: Periodically check the electrode slope using a two-point calibration. If readings drift or the slope is low, clean the electrode.
• Cleaning: For general cleaning, soak the electrode in 0.1M HCl or 0.1M HNO3 solution for 15 minutes, then in electrode storage solution for 30 minutes.
• Long-term Storage: For handheld devices, remove batteries during long-term storage to prevent corrosion. Store all measuring equipment in a non-humid environment, referring to manufacturer instructions.
