P600 Series Precision Handheld Reference Thermometers
  • ±0.03°C System Accuracy
  • NIST traceable certificate provided
  • Dual line display with differential function
  • Probes include unique calibration code read by meter
  • Fast-mode displays 4 readings per second
  • New intrinsically safe model (P650-EX)

For highest precision in a handheld meter and loaded with functionality, you won’t need to look any further than our P600 series thermometers. With system accuracy to ±0.03°C, and NIST-traceable calibration certificate with test data, this precision thermometer is an ideal lab standard.

With our dual channel models (P655 and P655L), you can select a simultaneous display of both channels, or a differential measurement for checking uniformity of baths or in- and outflow measurements. The dual line display is customizable to your needs. Also displayed are functions to track MIN, MAX, and HOLD.

With our P655L logging model, you can select a recording interval to store up to 2,000 readings, or you can chose to record temperatures ‘on demand’. Interval logging can be set from 1 second to 30 minute intervals and then quickly transferred to your PC with our optional Smartgraph software.

There’s more. Select our fast-mode and change the measuring interval from 1 second per reading to 4 readings per second. For prolonged battery life, the P600 series meters can be set to turn off automatically after 30 minutes. For applications that require temperature displayed in basic units, these meters can be switched to display in Ohms.

For intrinsic safety with high precision, we now offer the P650-EX which is certified with an (EEX ib IIb T4) rating.  The P650-EX offers ±0.03°C precision in areas where explosive gases may be present and includes an IS rated 9V “D” cell battery for up to 20 hours continuous use.

You won’t find a better handheld reference thermometer on the market with a system performance better than ±0.03°C for this price. And packed with functions you’ll typically find in a laboratory benchtop meter. Check out the specs and check out the competition.
