N2O Analyzer

The IRIS 4600 N2O Analyzer uses mid-infrared laser absorption spectroscopy to simultaneously measure nitrous oxide and water vapor concentrations. Continuous measurement allows for the calculation of the nitrous oxide dry-mole fraction at sub-ppb levels. The analyzer is capable of making measurements in the range 50 to 4,000 ppb.

Separator for Groundwater Remediation

This Oil/Water Separator is designed to remove oils, grease and solids at groundwater remediation sites. The effluent quality is 10 ppm or less of oil droplets 20 micron and larger. The separation process is automatic and uses no moving parts. Flow rates range from 15 to 5000 gpm. The company also manufactures a full line of industrial wastewater equipment and systems. — Ellis Corporation, 630/250-9222, www.elliscorp.com Circle 3 on Card

Pressure Gauge

The DPGM409 features Gage, Sealed Gage, Absolute, Compound Gage, Vacuum, and Barometric pressure ranges. Its core is a micro-machined silicon sensor with a 0.08% accuracy. Each unit is supplied with a 5-point NIST traceable calibration certificate and is tested to industrial CE standards. A user-selectable analog output is standard on all models, and a built-in wireless transmitter option is available.

The electronics are enclosed in a stainless steel and ABS housing that is washdown rated.

Sampler

The Discrete Interval Sampler is stainless steel and attached to LDPE tubing mounted on a convenient reel. It is pressurized before being lowered to prevent water from entering the sampler until the desired zone is reached. It is used to profile open bodies of water and boreholes, and collect discrete samples without purging. — Solinst Canada Ltd., 905/873-2255, www.solinst.com

Online Analyzer

The TOC-4200 utilizes a 680°C combustion catalytic oxidation method to support analyses from 5 mgC/L to 20,000 mgC/L full-scale. The TOC-4200 can measure samples with TOC concentrations from 0 to 1mgC/L. The TOC-4200 now offers ECO mode that only uses carrier gas and operates the sampling pump when it is needed. The TOC-4200 also has a web-based monitoring function.

Circle6onCard Toxic Gas Multi-Actuator Valve Controller

The Duplex Model II control system quickly closes up to two Eclipse™ actuators on toxic gas cylinder and ton container valves when activated by panic buttons or remote gas sensors. The system applies 50 foot-pounds of torque for emergency closures of the cylinder valve.

All Fire Codes recognize and approve the “automatic-closing fail-safe shutoff valve” system in lieu of a scrubber treatment system. With a

Duplex Model II, your SCADA system can be provided with actuator closure status and error codes to quickly analyze problems. — Halogen Valve Systems Inc., 877/476-4222, www.halogenvalve.com
