PH TESTER TECPEL
PH TESTER TECPEL – High-Precision Waterproof Pen-Type Digital pH & Temperature Meter
The PH TESTER TECPEL (specifically model pH-709) is an IP67-rated waterproof handheld meter engineered for accurate, real-time pH, oxidation-reduction potential (ORP/mV), and temperature measurement. Built with a high-performance microprocessor architecture, this compact instrument delivers fast response times and stable liquid analysis across field testing, laboratory environments, and industrial water treatment systems.
Featuring a dual-line LCD display, the meter simultaneously displays the live pH or mV reading alongside liquid temperature. Integrated Automatic Temperature Compensation (ATC) automatically adjusts measurement calculations based on liquid thermal variations from 0°C to 90°C.
As illustrated in the product image, the meter features an ergonomic, blue-and-white IP67 waterproof housing designed with an angled display screen for effortless reading, alongside tactile front buttons (H/M, MODE, CAL/Power) for quick operation.

Operating Guidelines and Best Practices
CALIBRATION TIP: Perform push-button calibration regularly using standard buffer solutions (pH 4.00, 7.00, or 10.00) to maintain measurement accuracy.
Electrode Storage: Always keep the glass bulb moistened by adding a few drops of electrode soaking solution inside the protective cap when not in use.
Rinsing Technique: Rinse the electrode tip with distilled or deionized water between different fluid samples to prevent cross-contamination.
Industrial Applications and Environmental Testing
Beyond general laboratory testing, integrating a PH TESTER TECPEL unit is ideal for hydroponics nutrient monitoring, swimming pool chemistry control, food and beverage processing, boiler water analysis, and environmental compliance sampling. The instrument’s fast microprocessor architecture ensures rapid response times even in low-conductivity water samples.
