Solving Axial Temperature Gradient Challenges in Dry Wells
Source: | Author:Y | Published time: 2025-06-27 | 1 Views | Share:

The Problem
Studies show temperature gradients in dry wells can reach ±0.18°F near the well mouth, causing significant calibration errors6.

Solutions

  1. Dual-Zone Control: Fluke’s Metrology Well actively adjusts top/bottom block temperatures to improve uniformity8.

  2. Probe Depth Optimization: Experiments using platinum RTDs confirm inserting probes ≥150 mm minimizes gradients610.

Industry Impact
Pharma labs using deep-insert probes (e.g., 170 mm Kaye wells) report 0.1°C uniformity in sterilization validation2.
