Be prepared for on-site measurements with the UV254 Dip Probe. 

UV254 Dip Probe

For handheld application, the Dip Probe is a submergible in-situ measuring device for UVT (%), UVA (Abs.) or for surrogate measurements of Total Organic Content (TOC), Dissolved Organic Content (DOC), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD) and other organic parameters.

Portable, durable and easy to use, the Dip Probe is a combination of our stable UV254 probe and our innovative Go! controller for the perfect all-rounder in a tough, handy case. The Dip Probe is powered with a long-life, rechargeable, Li-Ion battery and comes with a spare battery for those long days of measuring. The Dip Probe can be submerged by hand for portable measurements, left fixed in an open channel for continuous measurement or floated for example in a side stream of a river.

One of the key benefits of the UV254 Dip Probe is the ability to save your calibration to up to 16 locations for repeatable, reliable results without the hassle of excessive recalibration.

The simple and user friendly interfaces allows the operator to have control of their measurements and data. With straightforward integration with Excel for data export. 

Selection of probe pathlength is key to ensure you get the correct range and accuracy for your application, we offer a range of pathlengths to cover all water no matter how clean or dirty. The general rule is the lower the pathlength the higher the range, and the higher the pathlength the higher the accuracy. Contact our team to find out more about probes and find out if the Dip Probe is the right option for you.

 The Dip Probe comes with a Light-shield to protect the probe from interference of ambient sources of UV light (The sun for example). Perfect for river water monitoring, Water Treatment and Wastewater Treatment Plants.
