J-KEM® Temperature Controller Model 270   The Temperature Controller Model 270 was design  for processes requiring uncompromising safety. The only temperature controller available with a built-in independent backup controller to guard against heating accidents from equipment failure. Features: The desired temperature is entered into the digital display of the setpoint controller which regulates heating. A high temperature limit is then entered into the second digital back-up. If the reaction reaches the setpoint of the second controller, power is shut off from the output circuit until the unit is manually reset. Both controllers independently monior the reaction temperature and in the event that one controller fails, the other takes over to prevent a accident. The USB port on the back panel of the controller is an interface to J-KEM’s KEM-Net software.   Specifications: Dimensions: 9.25 × 7.75 × 3.4 in Power: 15 Amps @ 120VAC, 1800 Watts Weight: 7 lbs

J-KEM DVR-200-EV Digital Vacuum Regulator The DVR-200-EV has the same stainless steel pressure transducer inside, but the vacuum valve is outside of the controller. The value of this design is that the vacuum valve can be cleaned or replaced much easier than the valve in the classic DVR-200. Some applications, like distillations or stripping large volumes of solvent, can leave residues inside the valve which causes it to fail. Replacing the vacuum valve is the most frequent repair that J-KEM performs on the DVR-200. Replacing the valve in the classic DVR-200 is difficult and must be returned to J-KEM for repair. With the EV version, the user can disassembled the valve and wash it out, or even replace it in under 5 minutes. For large distillations or botanical applications, J-KEM recommends the DVR-200-EV. No Mercury 100% digital pressure entry and control Wetted parts are 100% stainless steel and Teflon Vacuum ramping feature eliminates bumping Resists: All organic solvents Acids Bases Water   Specifications: 100 watts. Vacuum fittings: 1/8″ NPTM. Warranty: Electronics 2 Years, Vacuum Valve 6 months (void if damaged by chemical buildup)
