The Iridesc F251 HydroSensor II is a professional-grade collapsible moisture probe engineered to quickly pinpoint moisture in house carpet and carpet cushion, while also checking floors, walls, and furniture where spills or intrusions may track. Its sensitive nickel-plated probe points are retractable for protection when not in use and alert you to moisture content above 17 percent, while a clear visual light and audible transducer beep accelerate or slow based on the amount of moisture detected—so you can survey large areas fast and decide exactly where to extract, dry, or spot-treat. A 31-inch reach collapsible shaft extends securely to save your back during inspections, then folds down for compact storage in your kit. Restoration contractors and carpet cleaning professionals appreciate the stainless steel construction designed for rigorous, long-term field use, and homeowners value its simplicity: just power it on with a standard 9‑volt DC battery and probe. Beyond water tracking, the HydroSensor II can help identify possible pet urine contamination on carpets and furniture, since urine salts often hold enough moisture to be detected; use a black light to confirm. Whether you’re scoping a leak, validating drying progress, or verifying a cleanup, this carpet tester delivers reliable, repeatable feedback and is an excellent way to replace a Dri-Eaz HydroSensor while maintaining trusted functionality and durability. - Brand: Iridesc - Type: Moisture Meter - Unit Quantity: 1 - Unit Type: Unit - Perfect for: house carpet - Compatible With: house carpet - MPN: 00001738 - UPC: N/A - Item Number: 00001738
