Dry Block Temperature Calibrator
Jofra ATC Dry Block Temperature Calibrator
Ametek’s Jofra ATC Dry Block Temperature Calibrators offer the accuracy of laboratory calibrators in a portable format. ATC dry block calibrators perform fully automatic calibration routines without the use an external computer. All ATC dry block calibrators can upload/download with computers via an RS232 serial port.
The ATC-155 model uses Peltier elements with “multi-stage-technology” that improve the efficiency and service life of the heating/cooling block. The ATC-320 and ATC-650 models have a dual zone heating block. This new design provides superior temperature homogeneity throughout the heating/cooling block. The performance of this new design is equivalent to a liquid temperature bath.

Sanitary Bimetal Thermometer
 Palmer Instruments manufactures the first bimetal thermometer to meet 3A sanitary standard 09-09. The thermometer responds faster than mercury-in-glass thermometers and eliminates the need for a thermowell because it is installed directly into the process. The thermometer uses replaceable thermometer cartridges. The replacement element comes precalibrated and ready for installation. This can reduce your thermometer replacement costs.
Palmer Sanitary Bimetal Thermometer come with a one-year warranty and free lifetime recalibration service.
