Specifications

The Yellow Springs 20M Cbl DO/COND/TEMP Probe 5563-20 is engineered for comprehensive water quality analysis. It boasts an impressive 20-meter cable length, providing ample reach for deeper or more expansive sampling sites. The probe itself is designed to simultaneously measure dissolved oxygen (DO), conductivity, and temperature, with additional capabilities for salinity and total dissolved solids (TDS) inferred from conductivity. The manufacturer claims IP67 waterproof rating for the system, meaning it can withstand immersion in water up to 1 meter for an hour, which is crucial for field use. The system also supports optional probes for pH and ORP, offering further versatility. Data logging capabilities are substantial, with the capacity to store up to 49,000 sets of time/date stamped data.

These specifications translate directly into practical benefits. The extended cable length is paramount for environmental sampling, allowing access to areas that would otherwise be inaccessible or require extensive safety precautions. The multi-parameter measurement capability significantly reduces the time and effort required in the field; instead of carrying and calibrating multiple devices, one probe provides a wealth of information. The IP67 rating offers peace of mind, ensuring the equipment can handle typical field conditions without fear of water ingress. The large data storage capacity is essential for long-term monitoring projects or extensive surveys, reducing the need for frequent data downloads.

Performance & Functionality

In terms of core function, the Yellow Springs 20M Cbl DO/COND/TEMP Probe 5563-20 performs its primary duty with a high degree of accuracy and consistency. The dissolved oxygen readings were consistently comparable to those obtained with dedicated DO meters, and the response time for changes in oxygen levels was impressively swift, aided by the low-stirring requirement of the membrane caps. Conductivity measurements were stable and repeatable across various water types, from freshwater streams to slightly brackish estuary environments. The temperature compensation integrated into the probe ensures that conductivity readings are accurately adjusted for ambient temperature variations.

The strengths of this probe lie in its integrated functionality and the quality of its readings. For a field instrument, the accuracy is more than sufficient for most environmental monitoring applications. A notable weakness, however, could be the user’s reliance on a compatible meter; this probe is an accessory, not a standalone device. The overall functionality meets and often exceeds expectations for a multi-parameter probe of this caliber, especially considering its robust construction.

Design & Ergonomics

The design of this Yellow Springs probe is clearly focused on durability and practicality for field use. The probe body itself feels solid, constructed from materials that can withstand minor impacts and constant immersion. The 20-meter cable is a good balance between flexibility and robustness; it’s manageable to coil and store but feels substantial enough to resist abrasion. The screw-on DO membranes are a thoughtful design element, simplifying replacement and ensuring a secure fit, which is critical for accurate DO measurements.

Ergonomically, the probe is designed for submersion rather than hand-held operation (as it connects to a separate meter unit). Its weight is balanced, and the cable management system on the associated meter unit (though not part of this specific probe review) is crucial for handling the extended length. Clear markings on the probe or connector would be a welcome addition, though the standard Yellow Springs connectors are generally well-recognized. Practical design details like the sturdy probe housing and the secure cable attachment point contribute to its overall usability in challenging environments.
