Measures, graphs, and records PRTs thermocouples, and thermistors, making this reference thermometer ideal for field applications, laboratory measurements, and data logging. Additionally, this instrument provides high accuracy, a wide measurement range, logging, and trending.
Make accurate, consistent measurements… anywhere.
This instrument uses a technique called current reversal in high-end instruments to eliminate thermal EMFs, for precision temperature measurements. Special precision resistors and a highly stable reference voltage source maintain this reference thermometer's accuracy virtually insensitive to environmental temperature. Additionally, it can endure rigorous testing in temperature extremes and under harsh conditions of vibration, allowing professionals to take them anywhere they need to go.
INFO-CON connectors ensure correct temperature conversion
Inside the INFO-CON, a memory chip keeps calibration information for the attached probe. Simply plugging in the probe uploads the information to the readout, ensuring the correct temperature conversion for accurate, hassle-free measurements.
Probes may be locked by password to specific channels and readouts for security or for system calibration traceability. Plug any thermocouple with mini-thermocouple jacks into an optional universal thermocouple adapter for convenient measurement. Each thermocouple adapter or standard connector supports reference junction compensation (RJC) with its own internal precision thermistor.
Monitor trends in the lab or in the field
See trends graphically on the 128 x 64-backlit LCD display. You can change the graph's resolution at the touch of a button. Now it's easy to see when the temperature is stable, without statistics or long delays, or monitor processes over time to verify correct operation.
Document on demand up to 25 readings and associated statistics for easy retrieval. You can view the data through the display or by uploading it to a PC via RS-232 connection and 9940 software, included free. To monitor and log more data over time, use a PC and optional LogWare II software.
RS-232-to-USB adapters are available for those who prefer USB connectors. Battery power lasts at least 20 hours on three AA batteries, or use the dc power adapter for extended periods of measurement. Power saving features can be enabled or disabled for longer battery life or greater convenience.
Calibration, loop checking, plant startup, troubleshooting, maintenance, and repair are some of the varied duties that need a reference thermometer. Use it for a handy temperature reference in baths, dry-block calibrators, thermowell, clean rooms, engines, heat exchangers, furnaces, freezers, or anything else that must be calibrated, checked, or maintained.
