About this item

Get faster performance with miniature coil design.

All meters feature 0 to 5 VDC output signal for data logging or controlling other instruments

These low-cost flowmeters use thermal gas flow sensing technique that results in highly accurate readings and repeatability. All units are calibrated to air/nitrogen—call our Application Specialists for meters calibrated to other gases or gas mixtures. Meters feature a cable hub connector for a quick connection to a power supply and 0 to 5 VDC output cable; order power supplies/cables under accessories.

Flowmeters have low pressure drop across the sensor. The output signal can connect to a remote display, recorder, or any instrument that accepts a 0 to 5 VDC signal. Compact size makes it easy to carry around.

Wetted materials are anodized aluminum, 316 stainless steel, Viton® O-rings, and 316 stainless steel, and acetal fittings. Order rechargeable battery kit under Accessories.

Delivery: Includes two compression fittings and 36" (0.9 m) cable with bub connector.
