Introduction
A pen type conductivity meter is a compact, pen-shaped instrument used to measure the electrical conductivity of the water and the solutions, and it is used in the laboratories, the water treatment, the hydroponics, the aquaculture, and the many other applications. The pen type conductivity meter measures the conductivity by the measurement of the electrical current between the electrodes in the solution, and it provides the conductivity value, expressed in microsiemens per centimeter or in millisiemens per centimeter, with the temperature compensation; the pen type conductivity meter consists of a pen-shaped meter with the display, a conductivity cell or the probe, a temperature sensor, and the battery, and it is compact and portable, with features such as the calibration and the automatic temperature compensation; the pen type conductivity meter is used for the measurement of the conductivity of the drinking water, the process water, the wastewater, the hydroponic solutions, and the aquarium water, for the quality control, for the monitoring, and for many other applications, and it is an essential instrument for the convenient conductivity measurement. Pen type conductivity meters are used in the laboratories, in the water treatment, in the hydroponics, in the aquaculture, and for many other applications. With their pen shape, pen type conductivity meters are essential for the convenient conductivity measurement.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The pen-type conductivity meter is used in water quality testing, aquaculture, hydroponics, swimming pool maintenance, field environmental monitoring and educational settings to quickly measure the electrical conductivity of water and aqueous solutions. It supports drinking water quality checks, aquaculture pond monitoring, hydroponic nutrient solution management, field water survey and general water quality assessment. The pen design allows convenient one-handed operation for spot-checking at multiple locations, making it ideal for homeowners, aquarium enthusiasts, hydroponic growers, field technicians and students requiring immediate conductivity readings without laboratory equipment. It provides a simple indicator of dissolved mineral content and water purity.
Q2: What standards does the instrument comply with?
A: The meter complies with relevant IEC 61010 laboratory and field instrument safety standards. Conductivity measurement references ISO 7888 for water quality and applicable GB/T standards. Calibration should use certified conductivity reference solutions.
Q3: What is the warranty period for the whole machine and key components?
A: The whole meter is covered by a 12-month warranty. The probe and meter circuit are covered, while calibration solution and batteries are consumables excluded from warranty. Probe damage from improper storage, dropping or corrosive samples is also excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation is simple: power on, immerse the probe and read the display. No professional training is required, but users should follow calibration procedures and proper probe handling. We provide an operation manual and remote guidance.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration with certified conductivity standard should be performed periodically, typically monthly or when readings become inaccurate. Probe condition should be monitored and cleaned regularly. Full meter calibration is recommended every 6-12 months.
Q7: Are supporting consumables universal?
A: Calibration solutions are available from chemical suppliers. Conductivity probes may be model-specific for some pen designs. Long-term consumable cost is very low.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes measurement range, display units and branding. Additional probes and calibration solutions can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: No installation is required. The package includes the meter, calibration solution and instruction manual. On-site service is not included for this type of pen instrument.
Q10: What types of samples are compatible with this equipment?
A: The meter measures conductivity of aqueous solutions within the measurement range and temperature specification. Highly corrosive samples may damage the probe. Very high conductivity samples may exceed the range. Users should select the appropriate range for their application, follow proper calibration and storage procedures, and be aware that pen-type meters provide indicative readings suitable for field screening; for precise quantitative work, a benchtop conductivity meter with calibrated electrode is recommended.
