The Waltron Aqualert 6051 Hardness Analyzer is an advanced water quality monitoring instrument designed to measure total hardness in water as calcium carbonate (CaCO3). The Aqualert 6051 delivers reliable and affordable automation using titrimetric technology, with a fully automatic, user-friendly design, minimal maintenance requirements and long-lasting reagents.

The unit features high accuracy (±5%) and repeatability (±2.5%) across a wide measuring range of 0.22 to 534 ppm as CaCO3. A 3-inch LCD interface with an intuitive graphic overlay simplifies operation. The system includes two relay outputs, an analog 4–20 mA signal, and an SD card for easy data extraction. With a short cycle time of approximately 3 minutes and no routine calibration required, it provides efficient and mistake-proof monitoring. The unit is housed in a durable ABS, stainless steel, and PVC enclosure, and operates reliably within standard industrial environmental conditions.
