Techne - Model 4400 High Accuracy Thermometer Features 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. System Features High Accuracy- ±0.025°C from 0 to 100°C NIST Traceable with certificate Choice of Fixed Temperature Probes Hand-held Flexibility Hold reading button °F/°C Display Rate of Change Indicators Auto Shut-OFF Includes carrying case Applications Temperature Monitoring and calibration: Calibrate/verify your thermal cycler temperatures Use as a reference thermometer for your liquid bath Clinical Laboratory Quality Control Chemical & Petroleum Regulatory/Safety Metrology DNA Thermal Cycler Plate Uniformity Autoclave Integrity Specifications Specifications Resolution: 0.01°C/0.01°F Display: LCD 4 1/2 digit 0.45" high.
