Alpha instruments Inc was founded in 2005, in Massachusetts, US. We specialized in the development and manufacture of low-pressure transducers, which were applied in HVAC, Critical Environments, Medical Industry, Semiconductor Equipment, etc. With our own R&D Center, we do basic research, also develop our transducers with our unique technologies. The designs of our products are based on decades of experience applied to new innovative ideas. Compared to other capacitive transducers, our extensively engineered, patented products provide better long term stability, more sensitivity, and higher over-pressure capability. Our products cover the pressure range of 0.1 inch H2O to 100 inch H2O, or 25 Pa to 25000 Pa. With our unique manufacturing techniques, we can readily produce transducers with custom pressure ranges. Alpha instruments Inc strives to provide the most advanced low-pressure transducers and bring superior Accuracy, Reliability and Value to our customers.
