The Humidity Sensor Evaluator (Model HSE) displays, monitors, and logs relative humidity (RH) and dry-bulb and dew-point temperature readings of resistive and hybrid capacitive humidity sensors via a computer’s USB port. Its software includes RH sensor response curves for hybrid capacitive sensors, such as the manufacturer’s HC-610. It is compatible with Windows 2000, XP and Vista, and requires either a USB 2.0 or a USB 1.2 port. It includes a humidity/dew-point calculator, two relative humidity sensors, and a thermistor.

The CPG 1000 digital test gage has an accuracy of 0.05% of full scale. With 18 selectable pressure units, it can handle virtually any test gage need, and is suitable for applications in calibration service, instrument and control workshops, laboratories, and quality assurance. Its rubber boot and stainless steel construction for the case and all wetted parts make it rugged and durable. The instrument features a convenient, user-adjustable reading sample rate that can be matched to the type of measurement required, allowing up to 10 measured values each second.

The FineAlyzer measures and analyzes dust particles in accordance with ASTM procedures to avoid  vigorous movement or friction of pellets during the fines separation process. The technology is based on the principle that unwanted dust and fines will typically adhere to larger pellets and will be removed by rinsing the test sample with a liquid (preferably demineralized water). This process washes away dust and fines into a beaker. Particles are then poured into the filter collection unit, which separates the fines from the water.

ToughMeter Series 270 analog panel meters are designed to withstand harsh environments. They are available in 2.5-in. and 3.5-in. models, and have an accuracy of 2% DC and 3% AC. The meters have all-metal cases and polycarbonate windows, gasket-sealed bezels, terminals, and zero regulators that ensure dust and moisture protection to International Protection (IP) 66 code. They are available with either pivot and jewel or taut band suspension. 

\TNTplus products work with the manufacturer’s DR 2800 portable and DR 5000 UV-Vis spectrophotometers to increase their productivity and minimize analytical errors. This line of reagent sets now includes copper, high-range nitrite, and mercury-free chemical oxygen demand (COD) testing kits. All three versions are suitable for use in wastewater applications, and the copper model is appropriate for testing potable water. TNTplus features barcode scanning, which enables automatic method and wavelength selection with the insertion of a vial.

The MiniScan EZ is a portable color-measurement instrument that can take product color readings on the plant floor, the production line and outdoors. Its lightweight (2.25 lb), ergonomic design features a rubberized handle for sure-handed carrying that virtually eliminates user fatigue when measuring a large number of samples. Measurements can be stored in memory for later printout or download to a PC.

The Innova-Sonic In-Line Model 206 is a digital transit-time ultrasonic flowmeter designed for liquid applications that require high mag­netic-flowmeter performance at an affordable price. It features a reading accuracy of ±0.5% and can measure down to zero flow in virtually any clean liquid, regardless of conductivity. This model works on conductive liquids only, meaning that it cannot measure hydrocarbons, distilled water or many nonaqueous solutions.

The Data-at-a-Glance PR125 pressure data logger features a minimum/maxi­mum display that enables chemical processors to quickly determine if pressures remain in required ranges. It operates at a 1-s sampling rate, and speeds data transfer by using flash memory cards and triple-speed USB-enabled data downloading. It is available in three models to handle 0–100 psi, 0–300 psi and 0–500 psi pressure ranges, and takes measurements in a variety of units: psi, atm, bar, mbar, in H2O, ft H2O, mm Hg, in Hg, Pascal and kP. A waterproof IP-68 case makes the data logger submersible.

The Model 350 high-temperature gel permeation chromatography (HT-GPC) system is specifically designed for the characterization of polyolefins and other synthetic polymers that are soluble only at elevated temperatures. It provides absolute molecular weight without extrapolation or correction, as well as molecular size (Rg and Rh to less than 1 nm) and intrinsic viscosity. It also gives information on branching, structure and aggregation in a single GPC/SEC (size exclusion chromatography) experiment.

Series 4007B pressure sensors are designed for harsh environments where space is a consideration. They are available with measuring ranges of 0–5 bar and 0–20 bar absolute for use at temperatures from –40 to 200ºC. The sensors have a direct chip exposure (DCE) design, which does not require a diaphragm. A piezoresistive measuring element measures static and dynamic events with excellent dynamic response. The sensing element relies on an implanted resistive bridge on micro-machined silicon, which minimizes hysteresis and repeatability errors.
