Need the most accurate thermocouple calibrations possible? The Hart Model 9112 Thermocouple Furnace gives you a broad temperature range to 1100°C, stability up to ±0.05°C and all at an excellent price.

In addition, this year were offering optional Calibrate-it software that completely automates the furnace and calibration processes.

Alternative calibration tools such as a sand bath or fluidized alumina bath have been used for calibrations up to 700°C but with very poor comparative performance.

Gradients of several degrees are common in a sand bath, along with poor stability, resulting in low-accuracy calibrations. Sand baths are also known to create a troublesome dust problem. Why buy poor performance and lab pollution?

• Combined stability and uniformity better than ±0.4°C 
• RS-232 serial interface standard 
• High capacity for simultaneous comparison calibrations
