Positive, negative and differential pressures can be measured within a full span accuracy of ±0.25 with the Series 616W Differential Pressure Transmitter. Units are enclosed in a polycarbonate case, rated NEMA 4X (IP66) and operate by sensing the pressure of air and compatible gases then sending a standard 4-20 mA output signal. Design enables operation in 2-wire current loops. A wide range of models are available factory calibrated to specific ranges. The span and zero controls are for use when checking calibration. They are not intended for re-ranging to a significantly different span. The LCD display allows local indication of pressure.
NIST CALIBRATION available in Product Configurator.

Quality Dwyer Products
Ordered this differential pressure transmitter for a project at our Williamsburg, IA site. The transmitter arrived when Dwyer said it would. We haven't installed it yet as the project is ongoing, but based on previous experience, we know that we can trust the quality products from Dwyer.

Not the quality i'd expect from Dwyer.
These are junk. Out of 3 units purchased, one came DOA, and even after warrantee repair, didnt work properly, a second one failed after less than 3 weeks of operation.

Is this 616W-10B-LCD Instrument factory calibrated?
Mike, these will not ship with Factory calibration, that would be an extra adder.
For factory calibration you will need to add -FC and cost will be 37.95 USD
For NIST traceable calibration adder will be -NIST and cost will be 223.60 USD.
