Thermometers may be calibrated at both hot and cold temperatures simultaneously with the Model 9009 Dual-Block Calibrator, eliminating the need to transport two separate temperature sources for field testing. The device combines two dry-block units into a single portable calibrator.
Housed in a water-resistant Pelican case which includes storage room for extra inserts and a power cord, the unit fits both hot and cold systems into a single, portable package. The cold block achieves temperatures from -15°C to +110°C while the hot block covers a temperature range of +35°C to +350°C. Pricing is $3,475.
