Products


With more than 20 years of temperature sensing experience, we can manufacture all types of RTD and thermocouple sensors to your specifications and satisfaction. Please fax or email factory with your specifications for a quick response.


Edison Onguard temperature monitors from Allestec. Models 4400 or 1616 monitors accept both thermocouple and RTD inputs. Highly reliable, these monitors in various styles have been a preferred choice since the 1960s.
The Allestec 800 series gas and fire control panel is designed to supervise and respond to the result of a gas or fire signal while maintaining simple panel annunciation.


Delphian gas monitoring systems. They're installed worldwide, wherever there exists potential danger from toxic and explosive gases. Onshore or offshore, inside or outside, Delphian provides safe solutions to meet the rigors of hazardous gas detection.



The Industry's most advanced 2-wire µP-based transmitter with HART protocol for head mounting or rail mounting. Also loop- and line-powered digital indicators.


A complete line of industrial pressure switches manufactured by the Solon Industrial Controls Division. Included are vacuum, differential, hydraulic, bellows actuated, diaphragm actuated, piston actuated, explosion proof, gauge indicating and temperature compensated pressure switches. Other manufactured controls include pressure actuated pneumatic valves, gas density monitors and electronic density monitors.


Removable insulation with convenient, easy-to-use hook-and-loop fasteners. Installs, removes, and then reapplies with ease following testing or maintenance. Takes just minutes, decreasing down time for repairs and fugitive emissions monitoring. Weather resistant for use outdoors. Protects employees from burns.


Industrial-grade compressed air dryers with the highest adsorbtion capacity. Point-of-use desiccant compressed air dryers remove moisture, water, oil, solid air particles and other contaminants from your compressed air.
The super-dry air tool dryer & protector -- a desiccant compressed air dryer specialized for compressed air tools -- consistently delivers dry, clean air.


Voltage detectors. Zero-tolerance solution provides safe electrical shutdowns in industrial environments. Prevent arc-flash hazards during maintenance work on 3-phase systems. Prevent electric shocks in the work place.
Ground fault monitors. Detect ground faults or phase failures (phase loss, phase reversal, phase unbalance) and alert personnel.
3-Phase monitors. Protect 3-phase electrical equipment such as motors, compressors, pumps, fans, etc.
