Portable Pocket Tester Kit – pH5, pH+mV+Temp, Interchangeable Probe

Portable Pocket Testers are compact digital pH-measuring instruments designed for routine water and sample testing across laboratory, educational, 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 and temperature measurements wherever testing is required.

Intended Use & Applications

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

It is ideal for measuring pH levels, oxidation-reduction-related values, and temperature in water-based samples, nutrient solutions, beverages, and other 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 immediate measurements are required.

Accurate pH Measurement & Simple Operation

The tester measures pH values from -2 to 16 pH with ±0.01 accuracy and 0.01 pH resolution. It also measures mV from -1000 mV to +1000 mV and temperature from 0 to 60°C with ±0.2°C accuracy.

Push-button calibration allows adjustment from one to three calibration points using pH 4, 7 or 10 buffers, 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.

Complete Starter Kit & Accessories

The complete kit includes calibration buffers, electrode storage solution, batteries and accessories required for immediate use.

Supplied with two AAA batteries, this tester offers an expected battery life of more than 200 hours and supports rechargeable AAA batteries where suitable.
