2441 Laboratory Grade Portable Flow Meter
Brand: Kurz InstrumentsThe Model 2441 Lab Grade Portable Flow Meter is excellent and well-suited for industrial hygiene and HVac measurements. The dual-sting ceramic sensor is mounted in a ¼" diameter, 13" long sensor support with a shield/extender. The ceramic sensor provides a faster response time than the standard sensor Features:
- Excellent sensitivity to low velocities
- Insensitive to dirt and particulates in the flow stream
- User-configurable low velocity cut-off, reference conditions, time constraints, and flow area
- Velocity‐temperature mapping for wide ranging velocity and temperature
- Sensors do not overheat at zero flow by using a unique constant temperature control method and power limiting design
- Sensor lead-length independent circuitry
- Insensitive to installation angle
