NKE Water Monitoring Instruments Quality Testing Equipment plays a crucial role in assessing the safety and suitability of water, helping you to analyse water with user-friendly, portable equipment. Regularly monitoring and maintaining water quality ensures safer water, meeting both environmental and compliant water standards.

Whether you're after a multiparameter probe to monitor various water quality parameters, or a water level indicator, we will have something for you within our extensive range. We have an excellent selection of multiparameter water monitoring probes suitable for a range of applications. They each allow you to add extra sensors. All probes in our range are constructed from tough marine grade aluminium that has been hard anodised. This makes them suitable for use in both fresh and salt waters.

We also stock many other products to help you with water analysis, including data convertors and temperature loggers. You can buy individual probes, or opt for full water monitoring kits. There is a choice of both basic and advanced packages, allowing you to find and buy the more suitable tools for your projects.
