Portable Vibration Meter
PVM 100 handheld meter measures equipment vibration in terms of acceleration, velocity, and displacement. To use, attach the accelerometer, press one button to select acceleration, velocity or displacement, and hold it down to freeze the metric or English output on the digital display. To further pinpoint a noise source, plug headphones into the top-mounted jack. More info at controlglobal.com. Wilcoxon Research; 301/216 3039; www.wilcoxon.com
On-line H2S Analyzer
H2S-220 fiber optics diode array UV spectrophotometer performs online H2S monitoring. The diode array corrects for species that have interfering absorbencies, and can measure very low and very high levels of H2S with the same analyzer. The unit measures 1,024 discrete frequencies between 190 nm and 800 nm with a 1.0 nm resolution. Output signals include 4-20mA and Modbus TCP/IP. Applied Analytics; 888/461-0080; www.a-a-inc.com
Safe H2S Gas Sensor
TS Series hydrogen sulfide gas detectors can be used in general purpose, intrinsically safe, or explosion-proof areas to sense H2S over a range of 0 to 100 ppm in temperatures from -40 to +50 °C. Models are available with 4-20 mA output, dual-redundant Modbus communications, self-calibration, fault codes for troubleshooting, and a built-in LCD indicator that provides local status, fault and calibration data.

Photoionization Detector
2020ProPlus photoionization detection instrument is suitable for TVOC survey applications, including OSHA compliance, confined space pre-entry, emergency response, site characterization, fugitive emissions and law enforcement. It has a dynamic range of 10,000 ppm with 0.1 ppm precision to 100 ppm, and 1 ppm precision up to 10,000 ppm. More info at controlglobal.com. Photovac; 781/290-0777; www.photovac.com
Gas Monitor
Gas-Max Monitor is available in toxic, LEL and dual-monitor configurations. The dual configuration allows both a toxic sensor and an LEL sensor to be incorporated into the same unit, thus reducing space, simplifying installation, and decreasing installation costs. A real-time clock/calendar allows logging events such as alarms and calibrations. More info at controlglobal.com. Global Detection Systems; 409/927-2980; www.gdscorp.com
Gel Analysis
Gelatin Bloom Strength Test system includes a LFRA texture analyzer, two baths, and one refrigeration unit. Load capacities are 100 g to 4,500 g. Standard probes, fittings and accessories are available for standard applications. Industrial applications include pharmaceuticals, personal care products, rubber, wax, sponges, soaps, paints, caulking and adhesives.

Stream Selector Improves Analysis
SSV series stream selector system delivers a representative sample from multiple sample streams to one analyzer. These modular assemblies are ANSI/ISA 76.00.02 compatible, and accommodate multiple process streams in a limited space. Each stream is controlled by a double-block and bleed (DBB) module to eliminate cross contamination, and maintain sample integrity. More info at controlglobal.com.

FTIR Gas Analyzers
FTIR gas analyzers provide real-time, multi-component, extractive, gas-phase analysis for process optimization/control and specialty gas QC applications. The hermetically sealed industrial spectrometer has externally mounted, corrosion-resistant gas cells. Cell path lengths range from 1 cm to 20 m. Thermal isolation from the spectrometer allows operation from ambient to 240 C, allowing moist sample streams to be analyzed without condensation. Midac; 714/546-4322; www.midac.com
Single-gas Detector
Altair detector can monitor carbon monoxide, hydrogen sulfide or oxygen. Carbon monoxide and hydrogen sulfide versions can operate for more than two years. Its alarm system has two bright LEDs, a piercing audible alarm, and a vibrating alarm to ensure that no alarm condition goes unnoticed. The unit automatically records the last 25 alarm events.
