Online counters (e.g., LWL-3) are installed on equipment for 24/7 continuous monitoring with data upload and remote access. Choose based on whether you need mobile testing or fixed continuous monitoring.

Our sensor range covers: DR-400 (4-in-1: viscosity+density+dielectric+temperature), DR-500 (5-in-1: +moisture), DR-600 (6-parameter, intrinsically safe), HWR series (moisture/water content), LWTD series (trace moisture). Parameters include temperature, density, viscosity, dielectric constant, moisture, acid value and more.
