FAQs of DIGITAL PH METER (HANDHELD) 131, 132 & 133:
Q: How do I calibrate the DIGITAL PH METER (HANDHELD) models 131, 132, and 133?
A: Calibration is performed manually and can be conducted at up to three points using standard buffer solutions. Follow the instruction manual to calibrate, ensuring accuracy over the full pH 014 measurement range.
Q: What is the recommended process for measuring pH using this device?
A: To measure pH, immerse the glass electrode in at least 20 ml of your sample, ensuring the probe tip is fully submerged. Wait for the display to stabilize (under 5 seconds), then note the reading on the digital LCD.
Q: Where can these handheld pH meters be effectively used?
A: These meters are suitable for laboratory environments, educational institutions, field testing sites, and industrial settings across India, owing to their portability and robust design.
Q: What benefits can I expect from using a handheld digital pH meter?
A: The handheld design allows for on-the-go measurements, quick response time, ease of handling, and reliable accuracy, making it ideal for laboratories that require frequent and efficient pH analysis.
Q: When should I replace the electrode, and what is its typical lifespan?
A: The glass electrode generally lasts between 6 and 12 months with typical usage. If readings become unstable or calibration cannot be maintained, its time to replace the electrode.
Q: What type of battery powers the instrument, and how often should it be replaced?
A: These meters use a standard 9V DC battery. Battery life varies based on frequency of use, but replacement is straightforward and can be done when the display indicates low power.
