Check all of your thermometers against an affordable NIST-Traceable reference thermometer that’s accurate to ±0.015°C (includes the meter and probe). Choose from several precision calibrated RTD probes.
New Model P795
Our new P795 model is the most accurate thermometer of the series and includes data logging capability to 4000 readings and resolution to 0.001°. Also new to the series is a USB connection for downloading data. With optional software you can graph temperature over time, and set up the instrument for real time recording.
Order a P795 probe and the NIST-Traceable calibration data is already included; pre-programmed into an EEPROM located inside the connector. Simply connect the probe and when the meter is powered on the coefficients are automatically downloaded into the meter’s memory. The P795 also accepts P600 series probes via manual probe coefficient entry.
P600 Series
Each P600 Series thermometer includes a NIST-Traceable calibration report for both the probe and meter. Together accuracies of ±0.03°C can be achieved for testing all types of temperature sensors. Each precision probe is individually calibrated and a unique calibration code is generated that is read by the meter.
Our P655 includes 2 channels and a multi-line display for indicating both channels or a T1-T2 measurement. A fast response mode allows for a measurement update of 4 readings per second. Records Min, Max, and also freezes the display with the Hold feature. For two channel high precision data logging, chose our P655L with a memory capacity of 6000 readings.
You won’t find a better value at this precision anywhere. Compare this precision to any RTD system and you’ll pay over $2000.
