Equipment Roundup: For Measurement Technologies, Itís a Smaller World After All
A look at Endress + Hauserís shrinking vision of the future, and a roundup of the latest level, flow, pressure, and temperature products for pharma applications.

In addition to its sanitary temperature gauges, Lumenite Control Technology has expanded its offerings of sanitary (i.e., no threaded gauges, clean-in-place) pressure gauges for pharma applications. The LSPG and LSDPG conform to all 3A sanitary standards with ANSI grade "A" accuracy, and are available in multiple types of sanitary connections. They can withstand an ambient temperature of 300°F.
The Digital Pressure Gauge platform from Anderson Instruments is designed for monitoring critical pressures in sanitary applications. The switch version includes 2 fully adjustable switches with low-voltage relay outputs for simple control or alarming. The gauge has a battery-powered, hi-resolution digital display.
Veriteq Instruments has just released a data recorder for measuring multiple temperature environments simultaneously. The palm-sized 1016/1416 series (photo) is designed to record a group of chambers (up to 4) including -80°C ultra-low temperature freezers, fridges and incubators.
It’s a convenient solution “when there is a close grouping of temperature-sensitive products being held at different set-points,” says VP of Marketing Ken Appel. Using a single logger to do the job of several can reduce equipment and calibration costs, he says. The logger also features automated alarm notification and reporting with a browser-based software.
For lab and plant environmental temperature and humidity monitoring, Hart Scientific (a division of Fluke Corp.) has just released the 1620A paperless temperature and humidity data logger (photo), with wireless and Ethernet capability. The 1620A—aka the “DewK”—is a thermo-hygrometer that accepts inputs from one or two sensors, and can be mounted which may be mounted directly on the base unit or remotely (up to 30 meters). The device’s memory stores up to 400,000 date and time-stamped measurements, though data collected may also be sent in real time to a PC. Hart also offers software for the simultaneous monitoring of many instruments, with alarm triggers included.
Two Dimensional Instruments’ ThermaViewer is a combination data logger and chart recorder that that monitors and documents temperature or temperature/relative humidity. The panel display shows temporature history charts, with scrolling or zoom capability. Each sensor stores up to 80,000 data points—that is, a year’s worth of temperature history if samples are taken every ten minutes. While not wireless, the sensors come with a 20-foot wire for remote monitoring of temperature or temperature/RH. Best of all, it needs no pens or paper.
REOTEMP’s has improved its line of clean-in-place Sanitary RTD’s are designed for temperature sensing in pharmaceutical and biotech applications (photo). Sanitary RTD’s (resistance temperature detectors) are generally used where material contamination and accuracy are paramount. Reotemp’s have polished all 316 Stainless wetted parts, and a tri-clamp design for easy installation.
Data Translation’s new TEMPpoint is a standalone, highly accurate temperature measuring instrument with up to 48 channels (photo). Geared toward bioprocessing, the box allows multiple thermocouple, RTD, or precision voltage measurements to be taken simultaneously (with 24-bit resolution), then viewed, graphed, or exported to Excel. USB and Ethernet versions are available. No programming is necessary, the company says—simply plug and play. On the software side, a variety of PC- and web-based applications (such as those for traceability) are available.
British company Thermal Detection offers temperature sensors for pharmaceutical autoclave operations. The Steriprobe (Sterimaster in the U.S.) load and chamber probe withstands harsh chamber conditions to provide a leak-free chamber entry.
MadgeTech has just released a line of ultra low temperature data recorders, for temperatures to -86°C. The Cryo-Temp uses a USB docking station hooked to a PC. The memory goes to 30,000-plus readings per channel.
