Portable Pocket Tester Kit – PC5, pH+mV+Cond+TDS+Salinity+Temp, Interchangeable

Portable Pocket Testers are compact digital measuring instruments designed for routine water and sample testing across laboratory, education, environmental and industrial applications.

Featuring a replaceable probe design, three-button operation and a large 3-colour backlit LCD display, this handheld tester provides accurate pH, mV, conductivity, TDS, salinity and temperature measurements in one versatile device.

Intended Use & Applications

This portable multiparameter tester is suitable for applications requiring fast and reliable analysis, including aquaculture, aquariums, food and beverage testing, environmental monitoring, horticulture, hydroponics, water treatment, schools and general laboratory use.

It is ideal for measuring pH, conductivity, total dissolved solids (TDS), salinity and temperature in water-based samples and compatible liquids.

Portable Design & Field Convenience

Designed for mobility, the compact pocket format provides easy handling and transport with the included lanyard strap.

Its lightweight design supports convenient testing in laboratories, classrooms, outdoor environments and field locations where multiple measurements are required.

Accurate Multiparameter Measurement & Simple Operation

The tester measures pH from -2 to 16 pH with ±0.01 accuracy and 0.01 pH resolution, mV from -1000 mV to +1900 mV, and conductivity from 0.01µS to 199.9mS with ±2% full scale accuracy and automatic scale resolution.

It also measures TDS from 0.01ppm to 199.9ppt with a 0.40 to 1.00 TDS factor, salinity from 0.01mg/L to 100.0g/L and temperature from 0 to 60°C with ±0.2°C accuracy and 0.1°C resolution.

Push-button calibration allows adjustment from one to three calibration points using pH and conductivity calibration standards, helping maintain reliable measurement performance during routine use.

Waterproof Protection & Durable Performance

With IP67 waterproof protection, the tester is designed to support dependable operation in demanding laboratory, field and outdoor environments. The transparent body allows users to visually check if liquid has entered the unit, providing additional visibility during use.

Display Features & Measurement Indicators

The large LCD display with three-colour backlighting provides clear visibility of measurement values and operating status. Green indicates setup or measurement mode, blue indicates calibration mode operation, and red indicates an alarm or error condition.

Automatic temperature compensation helps maintain accurate readings across varying sample temperatures, while stability indicators and battery warnings assist with consistent operation.
