Low temperature constant temperature water tank -30~+80 340W LTB-250α 1 piece

It boasts precise temperature control and the durability of the stainless steel coil. The cooling capacity has been improved by adopting a high-performance refrigerator. The circulating water cooler uses a square coil made of SUS304, so it is compatible with pure water. (*If using pure water, please use a liquid with an electrical conductivity of 10μs/cm or more (low purity).) The refrigerant used is R-404, which has an ozone depletion factor of 0, making it environmentally friendly. The external circulation nozzle is installed on the front of the controller and can be freely rotated 180°. The temperature setting display uses a two-stage PV/SV display, allowing you to check the actual value and set value at a glance. By attaching the SB (support rod and bracket set), flasks and external sensors placed in the tank can be fixed with clamps.
