Save MONEY and time with the Dwyer 1200 Combustion Test Kit. See 1200 MODELS for MAGNEHELIC DIAL GAGE, INCLINED DRAFT GAGE or choose the Magnehelic Dial Gage or the Inclined Draft Gage

IIncludes portable Dwyer® Magnehelic® Draft Gage with large 4" dial instead of No. 171 Inclined Draft Gage, 0 to .25"W.C. range in .01" divisions. Also has air velocity scale with 300 to 2000 F.P.M, range. No leveling necessary; no gage oil required. Kit is otherwise identical to Model 1200-A and weighs only 7 lb 5 oz. OPTIONAL: On special order, the portable Dwyer® Model 460 Air Meter may be substituted for the No. 171 Inclined Draft Gage.

Dwyer's 460 Air Meter Complete Kit includes air meter, return and supply grille probes, angle connector, cleaning materials, instruction card, air velocity calculator, carrying case and one extra plastic ball in plastic tube. Click on Details to see more!

The new Series 641 Air Velocity Transmitter is the ideal instrument for monitoring air flow with its 16 field selectable ranges this Transmitter provides it the versatility to be selected for several air flow applications. transmitter uses a heated mass flow sensor which allows for precise velocity measurements at various flow rates and temperatures.
The optional LED produces a complete, low-cost solution for local indication of air flow. APPLICATIONS: Exhaust Stack Flow Monitoring Air Control in Drying Processes HVAC Air Velocity Measurements Fan Supply and Exhaust Tracking

The Series 641RM is the ideal Air Velocity Transmitter instrument for monitoring air flow.Remotely Mounting Electronic Enclosure. This transmitter uses a heated mass flow sensor, which allows for precise velocity measurements at various flow rates and temperatures.

The Series 641B Air Velocity Transmitter uses a heated mass flow sensor technology. It has four user-selectable ranges from 250 FPM to 2000 FPM with four corresponding metric ranges of 1.25 MPS to 10 MPS.

Dwyer's 660 Air Velocity Monitor Continuously Measures Fume Hood Airflow. The most affordable way to monitor airflow through laboratory fume hood. Installed in the fume hood side fascia and connected to the interior sidewall via 1-1/8" flexible tubing. As the exhaust fan draws air through the device, a sensitive constant temperature thermistor measures flow and lights a green (normal), yellow (high) or red (low) LED. An audible alarm also warns of low flow and requires manual resetting. Mounting holes fit standard single gang electrical box. SEE DETAILS FOR SPECIFICATIONS

Economical and reliable power supply is suitable for powering all Dwyer pressure, temperature or air velocity transmitters, Like the RH/RHL Humidity Temperature Transmitter. Inexpensive, open-frame design allows convenient access to input/output solder terminals. Auxiliary inputs are selectable for operation from power sources found worldwide. Compact size eases enclosure installations: 4-7/8" H x 4" W x 1-5/8" D.
