Item

Description

Stands, rods, and clamps to suspend and support your probes and thermometers.

Silicone oils, salt, and cold fluids in convenient, small quantities.

Model 7900 controller designed by Hart integrates the features of Hart's 2100 controller and can be used in place of the Rosemount 915 controller with Rosemount-designed baths.

Model 2100 and 2200 controllers can be integrated with homemade baths or other heat sources to achieve performance levels approaching Hart levels.
