Standard Platinum Resistance Thermometer
Conforming to all ITS-90 ratio requirements for standard platinum resistance thermometers (SPRTs), the Model 5698 working standard SPRT covers temperatures from +200°C to -661°C. Long-term drift is specified at ±0.006°C after 100 hours at maximum temperature. Typical drift at maximum temperature is just ±0.003°C. The strain-free, 25- pure-platinum sensor is enclosed in a 19-in. quartz glass sheath. Calibration options include both fixed-point and comparison calibrations. Price: $2200.

Data Loggers
The Pro series of NIST-traceable data loggers comprises two models: the TR220 for recording temperature and humidity and the SR200 for temperature alone. Each logger is equipped with a push-to-start button, which eliminates unusable pre-data during testing, shipping, and other monitoring conditions. The units store up to 32,512 sample points and are accurate to within ±1.8-F for temperature and ±2% for relative humidity. Dickson, Addison, IL. 800-323-2448. www.dicksonweb.com.
Acoustic Analyzer
The CESVA SC-30 is a Type 1 real-time octave-band analyzer with a frequency range of 31.5 Hz to 16 kHz. You can use the SC-30 as either a sound level meter or a spectrum analyzer, simultaneously measuring all parameters in either mode. It has a single dynamic range of 23 dB to 140 dB, so there is no need for range switching. The handheld meter comes with software that allows real-time retrieval of measured and recorded data, as well as transmission to a PC. Scantek, Columbia, MD. 410-290-7726; www.scantekinc.com.
Temperature-Measurement Module
Joining the DI-1000 family of PC-based instrumentation is the DI-1000TC, a module that performs temperature measurements using J, K, T, E, S, B, N, and R type thermocouples. The unit comes in four-channel and eight-channel versions with input-to-output, channel-to-channel, and channel-to-ground isolation.Temperature measurements range from -200-C to +1820-C, depending on thermocouple type. The DI-1000TC supports both RS-422 and Modbus communications. Base price: $495. Dataq Instruments, Akron, OH. 330-668-1444; www.dataq.com.
Rack-Mount Workstation
Custom-configured to meet your application requirements, the N1C 12A workstation’s standard 6U framework includes a 12.1-in. TFT LCD monitor, two USB ports, an external floppy drive, CD-ROM drive, 5.25-in. bay, and an internal 3.5-in. bay. You can choose a backplane with up to 14 slots and fill the drive bays with any combination of 70 different drives. CyberResearch, Branford, CT. 203-483-8815; www.cyberresearch.com.
8-Bit Digitizer Card
The CompuScope 82GC waveform digitizer for the CompactPCI/PXI bus employs two 8-bit ADCs, each running at 1 Gsample/s for dual-channel simultaneous sampling. In single-channel mode, the CompuScope 82GC achieves a sampling rate of up to 2 Gsamples/s. The 6U card comes with 2, 8, or 16 Msamples of on-board acquisition memory. Bus mastering enables data transfer from on-board memory to host RAM at a rate of 80 Mbytes/s. In addition, the CompuScope 82GC lets you capture both pre-trigger and post-trigger data for rapidly occurring events with no data loss. Base price: $7995. Gage Applied, Lachine, Canada. 800-567-4243; www.gage-applied.com.
Pocket PC Development Software
SoftWire graphical programming software allows the creation of complete Pocket PC applications within the Microsoft Visual Studio .NET environment. Applications can then be compiled and deployed on any Windows platform running the Microsoft .NET Compact Framework. With the addition of Pocket PC and Web service project types to SoftWire, you can build an end-to-end solution for mobile access to enterprise data without ever having to write a line of code. Price: SoftWire–$495 per development seat; Web Service Mobility Pack–$1499. SoftWire Technology, Middleboro, MA. 508-946-8900;www.softwiretechnology.com.
Smart Sensor Development Tools
With the TEDS library for LabView and the NI Plug & Play Sensor Development Kit, you can quickly integrate IEEE P1451.4 smart TEDS analog sensors into computer-based data acquisition systems. The TEDS library is an online database of downloadable LabView virtual instruments that implement basic TEDS management functions for reading and decoding TEDS sensors and editing and recompiling TEDS data according to IEEE P1451.4 specifications. The development kit is a complete data acquisition system for evaluating, using, and developing technology based on P1451.4 specifications. Price: NI Plug & Plug Kit–$3995. National Instruments, Austin, TX. 512-794-0100; www.ni.com.
Technical Plotting Program
Version 9.2 of Tecplot technical plotting software includes a general text loader, which provides a flexible, intuitive interface for getting ASCII data into Tecplot. The general text loader lets you scan data for titles and variables, set filters, and preview the processed data before importing. Tecplot V9.2 runs under Windows 95, 98, NT, 2000, and XP; Mac OS X; Linux; and most Unix workstations. Base price: $1495. Amtec Engineering, Bellevue, WA. 425-653-1200; www.amtec.com.
