Portable Pocket Tester Kit – COND5, Conductivity+TDS+Salinity+Temp, Fixed Probe

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 conductivity, TDS, salinity and temperature measurements wherever testing is required.

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, pools, schools and general laboratory use.

It is ideal for measuring 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 immediate measurements are required.

Accurate Conductivity Measurement & Simple Operation

The tester measures conductivity from 0.01µS to 199.9mS with ±2% full scale accuracy and automatic scale resolution. It also measures total dissolved solids (TDS) from 0.01ppm to 199.9ppt with ±2% full scale accuracy and a selectable TDS factor from 0.40 to 1.00.

Salinity measurements range from 0.01mg/L to 100.0g/L, while temperature measurements range 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 84µS, 1413µS and 12.88mS 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.
