Drop Test Kits

Simple, dependable water testing for a wide range of applications.


DTK Drop Test Kits provide a practical and cost-effective solution for water quality analysis across a wide range of industrial, commercial and water treatment applications.


Using straightforward test methods, the kits allow users to measure individual water quality parameters quickly and reliably without the need for complex electronic instrumentation.


Compact and portable, each kit contains the reagents, equipment and instructions required to perform the specified test, providing a convenient solution for on-site analysis and routine water quality monitoring.

A Wide Range of Testing Options

DTK Drop Test Kits are available for a broad selection of individual water quality parameters, allowing users to choose the testing capability most appropriate to their application.


From routine treatment checks to the investigation of specific water quality conditions, the range provides a flexible approach to testing without the need for a larger multi-parameter kit.


Depending on the test method, individual kits include the appropriate reagents, syringes, test bottles, test cells and accessories required to carry out the analysis.

Suitable for Multiple Applications

DTK Drop Test Kits are suitable for water quality monitoring across a variety of industrial, commercial and specialist applications where individual parameters require regular testing.


The range supports testing in potable water, process water, boiler and cooling systems, swimming pools, leisure facilities and wastewater treatment applications.


This versatility allows users to select individual tests suited to their monitoring requirements, providing a practical solution for both routine checks and specific water quality investigations.

Designed for Straightforward Testing

DTK Drop Test Kits use established testing methods designed to make routine water analysis simple and accessible for operators and experienced water treatment professionals alike.


Clear, step-by-step instructions guide users through the testing procedure, helping to ensure consistent operation and reliable results across regular monitoring activities.


The compact, portable format allows testing to be carried out directly at the sampling location or within a laboratory, providing flexibility across different working environments.

Convenient Replacement Reagents

Replacement reagents are available for applicable DTK Drop Test Kits, allowing existing testing equipment to remain in regular use without the need to purchase a complete replacement kit.


This provides a convenient and cost-effective approach to maintaining testing capability, particularly where individual water quality parameters are monitored frequently.


With replacement reagents readily available, users can replenish their kits as required and continue regular testing as part of an established water quality monitoring programme.

Supporting Effective Water Quality Management

Regular water quality testing helps operators identify changing conditions, assess treatment performance and determine when adjustments to operating processes may be required.


By combining established test methods with portable equipment and straightforward procedures, DTK Drop Test Kits provide an accessible way to carry out individual parameter testing without complex instrumentation.


This makes the range a practical solution for maintaining consistent water quality monitoring across industrial, commercial and water treatment applications.
