Ashcroft Inc
About
Ashcroft Inc., founded in 1852 and headquartered at 250 East Main Street in Stratford, Connecticut, is one of the world's oldest and most recognized manufacturers of pressure and temperature instrumentation, with over 170 years of continuous operation. The company holds ISO 9001:2015, ISO 14001:2015, and ISO 17025:2017 certifications, employs over 1,000 people, and distributes through more than 100 authorized distributors across 15 countries. Ashcroft's product portfolio spans pressure gauges (1279 Duragauge, 1259 Process, and stainless steel 1008S/1009/1209 series), pressure switches (A-Series through G-Series in watertight, NEMA 4X, and explosion-proof enclosures), pressure transducers and transmitters (E2G general purpose, E2F, E2S, G2, G3, T2, GC51, GC52), and the SL17 submersible level transmitter for groundwater and tank monitoring. Diaphragm seals and isolation rings (DF, 200/201, 202/302, 400-403/510-511, 80/81/82 series) isolate instruments from corrosive, clogging, or viscous media common in water and wastewater applications. The company also offers SMART Transmitter Assemblies combining transmitters with seals as pre-calibrated single-source solutions, bimetal and gas-actuated thermometers (EL/EI, C-600 Duratemp, S5500), thermowells in flanged, threaded, sanitary, and weld-in configurations, RTD probes (S10, S50) and thermocouples (S10, S50, S70), differential pressure instruments, and the ATE-2 calibrator. For potable water applications, Ashcroft provides NSF/ANSI/CAN 61-certified instruments. The company also operates multiple brands including Heise for precision pressure, Rüeger for temperature, Stiko, Weksler, and Willy.
