As with most high temperature fluids, a fume hood is recommended for operating temperatures above 150ºC.

Temperature Measurement Products ACCU-TEMP RTD INDICATOR   Copyright © 2001 Techne Incorporated

In many cases, our stated display accuracy may be enough for your application but we suggest using an independent reference thermometer to measure the temperature of your calibration bath, dry well block calibrator, fluidised bath or thermal cycler.  The Tecal Accu-Temp RTD indicator is a bench top high accuracy instrument, offering a two probe input and resolution of 0.001 at a lower cost than competitive units. Add one or two of our ITS-90 calibrated Model WSP660 PRT's to the Accu-Temp for high overall system accuracy. We also offer ITS-90 calibrations and recalibration on the sensors you supply or already own. Our low cost, high accuracy thermometer choice is the Model 4400. It offers four probe types one for general purpose use, another for 0.2 and 0.5 thermal cyclers and the third for 384 well thermal cyclers. This unit also includes a foam lined carrying case. All of our thermometer systems include a NIST traceable calibration certificate with all of the relevant calibration data.

Techne Model 4400 
High Accuracy Thermometer

Techne hand-held Model 4400 Series Ultra-High Accuracy Thermometers take metrology-level temperature measurement to the laboratory, the production floor, and the field. Ultra-high thermometer accuracy up to ±0.015°C is achieved because the thermometer uses extremely stable components and circuitry. Each thermometer is electronically calibrated, maintaining excellent repeatability. The 4400 System uses coefficients for the Probes with the Stienhart-Hart algorithm to calculate the exact temperature reading every time you plug in a probe to take a measurement. The 4400 series thermometers are configured and hardwired to the specified probe and calibrated as a system for high accuracy.  When one type of probe will do the job a hardwired system offers excellent repeatability with ultra high accuracy over a wider range.
