1. What is the measurement range and accuracy of the PH400F pH meter?
The PH400F measures pH from -2.000 to 20.000 with selectable resolution of 0.1, 0.01, or 0.001 pH and an accuracy of ±0.002 pH.
2. Can the PH400F measure millivolts (mV) and temperature?
Yes. The PH400F measures mV from -2000.00 to 2000.00 mV with 0.1 or 0.01 mV resolution and accuracy of ±0.1 mV or ±0.03% of reading (whichever is greater). Temperature measurement range is −10 to 135 °C (14 to 275 °F) with 0.1 °C resolution and ±0.1 °C accuracy.
3. How do I calibrate the PH400F and what buffer standards does it support?
The PH400F supports multi-point calibration (up to five points) and recognizes buffer standards from NIST, GB, DIN, USA and MERK. Calibration can be performed manually or automatically—follow the instrument prompts or the user manual for step-by-step calibration procedures.
4. Does the PH400F provide temperature compensation?
Yes. The meter offers automatic or manual temperature compensation to ensure accurate pH readings across different sample temperatures. For automatic compensation, use a compatible temperature probe as described in the manual.
5. How much data can the PH400F store and how do I transfer data to a computer?
The PH400F can store up to 500 data sets. Data transfer is supported via USB or RS-232 interfaces. Refer to the product documentation or supplied software/drivers for details on exporting and formatting recorded data.
6. What does the IP54 waterproof rating mean for everyday use?
An IP54 rating means the unit is protected against limited dust ingress and against water splashes from any direction. It is splash-resistant for lab use but is not designed for continuous immersion—avoid submerging the instrument.
7. What electrodes are compatible with the PH400F and how should I maintain them?
The PH400F is compatible with standard laboratory pH electrodes (check for connector compatibility in the manual). Maintain electrodes by rinsing with distilled water between measurements, storing the sensor in appropriate storage solution (never dry), and regularly regenerating or replacing electrodes that show drift or slow response.
8. Is the PH400F suitable for industrial, educational and research labs?
Yes. With its wide measurement range, high resolution and multi-point calibration, the PH400F is appropriate for chemistry labs, water quality testing, cosmetics, pharmaceuticals, education, and many industrial QC applications.
9. What power options does the PH400F support?
The PH400F operates using AC/DC power options. Check the product documentation for the required adapter specifications and any regional power requirements.
10. How often should I calibrate the PH400F?
Calibration frequency depends on usage and required accuracy. For routine lab work, calibrate daily or before critical measurements. For high-precision or regulatory testing, calibrate before each measurement session or sample batch.
11. What should I do if readings are unstable or drifting?
Check electrode condition and cleanliness, ensure proper temperature compensation, verify calibration with fresh buffer solutions, confirm probe connections, and inspect for air bubbles on the sensing junction. Replace the electrode if problems persist.
12. Does the PH400F come with software or drivers for PC connection?
The meter supports data transfer via USB and RS-232. Software or drivers may be provided by the supplier—check the product package or contact your vendor for included software and installation instructions.
