Customer Questions & Answers

  • Question: What is the Extech SDL100 PH and ORP Meter SD Logger used for?

    Answer: The Extech SDL100 PH and ORP Meter SD Logger is designed to measure the pH and oxidation-reduction potential (ORP) of liquids. This handy tool is ideally used in laboratories, aquariums, pools, and agricultural applications where understanding the acidity and electrochemical potential of a solution is crucial. The data logging feature allows users to track changes over time, making it invaluable for monitoring processes and ensuring optimal conditions.
  • Question: How does the SD logging feature work on the Extech SDL100?

    Answer: The SD logging feature on the Extech SDL100 allows users to store measurement data onto an SD card. This means you can record extensive data sets without worrying about losing any information. The device can log data at specified intervals, which is beneficial for long-term project tracking or research. Once data is recorded, it can be exported for analysis or reporting, making it perfect for professionals who need to maintain accurate records.
  • Question: Can the SDL100 measure temperature as well?

    Answer: Yes, the Extech SDL100 includes a temperature measurement feature alongside pH and ORP readings. This ability is essential as temperature can significantly influence both pH and ORP levels in solutions. Many applications, such as aquaculture and environmental monitoring, require constant temperature and pH tracking to ensure ideal conditions for aquatic life or chemical reactions. This multifunctionality makes the SDL100 a versatile tool for any technician or researcher.
  • Question: Is the Extech SDL100 suitable for home use?

    Answer: Absolutely! The Extech SDL100 is user-friendly and can easily complement home projects, whether you’re managing a home aquarium, maintaining a swimming pool, or simply monitoring the soil pH for gardening. Home users can benefit from understanding their water quality or soil conditions better, ensuring that plants thrive or that pools remain clean and safe. Its clear display and intuitive functions make it accessible for non-professionals as well.
  • Question: What are the calibration requirements for the SDL100?

    Answer: Calibration is essential for accurate measurements with the Extech SDL100. The device typically offers a one-point or two-point calibration system, which allows users to calibrate the pH sensor using standard buffer solutions. Regular calibration is recommended to maintain accuracy, especially if the meter is used frequently or over extended periods. This practice is vital, ensuring that readings remain reliable, particularly in critical applications like laboratory analysis or water quality monitoring.
  • Question: How do I replace the pH electrode on the SDL100?

    Answer: Replacing the pH electrode on the Extech SDL100 is a straightforward process. When the electrode reaches the end of its lifespan or shows inconsistent readings, it can be unscrewed and replaced. It's advisable to keep an extra electrode on hand for quick changes, enabling uninterrupted data collection. Users should follow detailed instructions in the manual for the replacement process to ensure proper installation and continued accuracy in measurements.
  • Question: Can the SDL100 be used for wastewater analysis?

    Answer: Yes, the Extech SDL100 is well-suited for wastewater analysis. With its ability to measure pH and ORP, it helps monitor water quality and treatment processes effectively. Regular monitoring can prevent harmful discharges and ensure compliance with environmental regulations. This functionality is indispensable for municipalities and industrial operators aiming to optimize treatment systems and maintain sustainable practices.
  • Question: What is the display feature like on the SDL100?

    Answer: The Extech SDL100 features a large, backlit LCD display, making it easy to read measurements even in low-light conditions. The clear interface presents pH, ORP, and temperature readings simultaneously, providing a comprehensive view of the sample conditions. This design is especially beneficial during fieldwork, where accessibility and visibility are critical for accurate readings and decisions.
  • Question: What is the power source for the SDL100?

    Answer: The Extech SDL100 is powered by AAA batteries, which are easily replaceable when needed. Its design allows for efficient energy usage, ensuring that the device can be used for extended periods without needing frequent battery swaps. This makes it convenient for outdoor or field applications where power outlets may not be available, ensuring reliability in a variety of situations.
  • Question: Where can I buy the Extech SDL100 PH and ORP Meter SD Logger in India?

    Answer: You can purchase the Extech SDL100 PH and ORP Meter SD Logger through Ubuy. They offer a comprehensive selection of electronic measurement tools, including this model, to ensure you can find exactly what you need for your pH and ORP monitoring requirements.

Extech Data Loggers Editorial Review

The Extech RE300 ExStik ORP Meter is a handheld device that measures ORP (oxidation-reduction potential) in various solutions. The full set includes six AA batteries, an SD card, a hard carrying case, sample buffers, a mini pH electrode, and a thermistor temperature probe. The meter's log is capable of datalogging information from 1 second to almost 9 hours, with data saved on the SD card. However, this product does not ship with thorough instructions. Customers have reported inConsistent and unreliable readings due to moisture penetrating the meter's compartment, which appears to be a design flaw. Some users have had difficulty getting Consistent baseline readings, which requires an attempt to decipher vague instructions. Others reported inConsistent readings even after receiving replacements. The product's probe must be purchased separately to measure ORP, although it is capable of measuring pH too. The device is made in China, and some issues could be due to a long journey that damages the probe. The Construction is excellent and much better than many other devices that have exposed electrodes.
