Product Description
pH Meters
We are a leading manufacturer of pH Meters. These meters are based on advanced micro controller based designs and allow display of pH, mv, temp on backlite LCD. Further, these also feature RS-232 interface as well as inbuilt RTC that makes them easy to function. Being GLP compliant meters, these meters also allow entry of buffer value, machine ID through keyboard for GLP print out. Other than this, these meters also have 3 point Automatic pH Calibration (with buffer standards 4.0, 7.0 & 9.2 pH) and 3 point manual pH calibration (using known buffer standards).

Precision pH Measurement Across ApplicationsThis digital pH meter stands out for its broad versatility in laboratories, water treatment, aquaculture, and industrial applications. Measuring from 0.00 to 14.00 pH with 0.01 pH resolution, it ensures reliable results wherever high precision is required. Its replaceable combination electrode and quick response time make it perfect for daily testing routines, and the compact, lightweight body enhances portability and ease of use.
Durable Design and User-Friendly FeaturesCrafted with an IP54 rated plastic body, the pH meter resists splash hazards and provides long-term reliability in busy laboratory or field environments. Features such as auto-off, data hold, and a clear LCD digital display simplify operation, while the replaceable electrode extends the instrument's usable lifespan. Its support for both battery and AC power ensures adaptability to various working conditions.
FAQ's of pH Meters:
Q: How do I calibrate the digital pH meter, and how often should this be done?
A: Calibration is performed manually using 2 or 3 calibration points, with standard buffer solutions. It is recommended to calibrate before initial use and regularly, depending on frequency and type of application, to maintain 0.01 pH accuracy.
Q: What is the recommended storage and maintenance process for this pH meter's electrode?
A: The replaceable combination electrode should be stored at room temperature in a dry place. After use, rinse the electrode with distilled water and keep it slightly moist when not in operation to maximize its lifespan of up to 12 months.
Q: When does the meter indicate low battery, and what are the power supply options?
A: The digital pH meter features a low battery indicator on its LCD display. It operates using a 9V battery for portability or can be powered by a 110-240V AC adapter, allowing flexible laboratory or field operation.
Q: Where is this digital pH meter primarily used?
A: This meter is suited for laboratory, water analysis, aquaculture, and industrial environments. Its robust construction and portable design make it ideal for both stationary and field work across various sectors in India.
Q: What benefits do the auto-off and data hold functions provide during pH measurements?
A: The auto-off feature conserves battery life by automatically switching off the meter when idle, while the data hold function freezes the current reading on the display, allowing users to record accurate measurements without rushing.
Q: How quickly can I obtain stable pH readings with this meter?
A: Stable pH readings are achieved in less than 1 second, thanks to the fast response of the pH electrode, making it highly efficient for processes requiring rapid and repeatable measurements.
