Indicators provide continuous visual insight into critical process parameters and display measurement values in real time. In horticulture, water treatment, industry and research environments, indicators help operators quickly assess current conditions without the need for manual measurements. Unlike controllers, indicators display information but do not automatically adjust the process. Looking to buy an indicator? Pay attention to display options, supported parameters, communication protocols and compatibility with your sensors and monitoring systems. Read more

Indicators are used to continuously display measurement values such as EC, pH, temperature, humidity and other environmental or process parameters. In horticulture, indicators provide operators with immediate insight into irrigation water quality, climate conditions and crop environments. In industrial and water treatment applications, indicators support operational monitoring and help identify deviations quickly. Continuous visual monitoring improves process awareness and supports faster decision-making.
Our indicators are designed for reliable and stable operation under demanding conditions. Many models support multiple sensor inputs and provide clear displays that remain easy to read under various lighting conditions. Depending on the model, indicators are available with analogue or digital communication options for integration into existing monitoring systems. Their robust construction makes them suitable for greenhouse environments, industrial installations and outdoor applications.
Are you unsure whether a simple display unit or a more advanced multi-parameter indicator is the right choice for your application? We are happy to help you select the best solution based on practical experience.
Different indicators are available for EC, pH, temperature, humidity and many other process parameters. Selecting the right model depends on the parameter being monitored, the number of measurement channels and the communication standards used within your installation.
Nieuwkoop BV offers a carefully selected range of indicators for professional use in horticulture, water treatment and industrial applications. With fast delivery and technical advice based on practical experience, we support you in selecting, installing and maintaining the right equipment.
