Porous Ceramics

Porous Ceramics

Porous Ceramics are an integral part of many soil-monitoring and sampling instruments. The ceramic matrix serves as the interface between the soil matrix and the instrument. The ceramic material is porous, and allows water to pass into and out of the instrument.  A pressure gradient across the ceramic wall will cause water to flow through more »

Mini-Tensiometers

Mini-Tensiometers

Mini-Tensiometers are used under conditions in which a tensiometer with a full-size ceramic cup cannot be used. These conditions might include: in a greenhouse environment to monitor plants growing in small containers; in laboratory column studies; or outside under turf, for measurements very near the surface. The mini-tensiometers are constructed with a length of flexible more »

Model Ten Dial-Gauge Tensiometers

Model Ten Dial-Gauge Tensiometers

The Model Ten tensiometer offers versatility as well as reliability. The dial gauge and ceramic cup are easily replaceable, and threaded connections allow easy attachment of accessories.

150-W Supply Targets LED Lighting

The GLC-150 series of constant-current ac-dc LED power supplies, which is said to deliver stable and reliable 150-W output power, suit virtually all LED lighting applications. Green Watt Power’s (a division of Calex Mfg.) GLC-150 series features a universal/full-range ac input voltage of 100 to 277 V ac. Six models are available: 2.8, 3.2, 3.75, 4.2, 5.0, and 6.25 A. All models have self-adjusting output voltage, from 15 to 54 V dc. They’re designed to IP67 standards in an extruded aluminum metal case measuring 8.98 in. (L) by 3.15 in. (W) by 1.78 in. (H). Efficiencies range around 93%, with active power factor correction greater than 0.90. The RoHS-compliant supplies incorporate overvoltage, overcurrent, and overtemperature protection.

Envirologger chosen for PetroSense oil and fuel detection

The PetroSense range of sensors from FCI Environmental is now supported by Envirologger. The probes can detect minute traces of hydrocarbons in soil or water and the data is transmitted instantaneously to a central server and relayed to the client on a web site, by email, SMS, file transfer protocol or via site manager software.

Applications include process water, wastewater, oil field produced water, separation vessel effluent, storm water run-off, bilge and ballast water, groundwater remediation monitoring, carbon filter bed breakthrough and heat exchanger leak detection.
