About testers and meters
Laboratory testers and meters provide fast, practical measurements for samples where quick decisions are important. These handheld and benchtop instruments cover parameters such as refractive index, pH, conductivity, salinity, TDS, soil conditions and basic water quality. In many cases they support rapid screening before more detailed analytical methods are applied.
Within this category on the COLO Lab Store you will find compact devices designed for field work, production lines and routine laboratory checks. Simple operation, short response time and robust housings make these instruments suitable for everyday use in education, industry, agriculture, environmental monitoring and quality control.
Types and applications
The range includes both single-parameter units and more advanced multi-function meters. From here you can move to the most suitable group and then refine your choice by measuring range, sample type, portability and data handling options.
INSTRUMENTS IN THIS SECTION
- Refractometers – quick measurement of concentration, Brix, salinity and refractive index.
- Soil testers – field assessment of pH, moisture, conductivity and basic nutrient status.
- Water quality units – portable tools for pH, EC, TDS and salinity in drinking, process and environmental water.
- Pen-type and pocket meters – ultra-compact devices for on-site checks and daily spot measurements.
- Multiparameter models – combined measurement of several parameters in one unit.
- Specialty testers – dedicated instruments for niche requirements, such as coating thickness or surface gloss (where available).
FEATURED: COLO.Science HANDHELD DEVICES
COLO.Science solutions are designed for clear readings, reliable performance and low maintenance. Intuitive interfaces, replaceable electrodes or sensors and stable calibration help operators obtain consistent results with minimal training. In addition, many models are suitable for both field and laboratory use, supporting quick decisions and routine documentation.
As the range expands, this section will remain the starting point for rapid laboratory and field measurements, helping you select the right instrument for screening and routine monitoring tasks.
