Profile: Electronic Development Labs, Inc. is a manufacturer of precision temperature products. We specialize in the field of temperature measurement and control. The Cryo-Cal® utilizes the phase change point of liquid nitrogen to establish a reference temperature. The analog instruments are ideal for applications where we need intrinsically safe instruments. These instruments are designed for fast readings and showing reliably trends. The MX temperature controller is a totally self-contained pre-wired system which incorporates the Fuji PXZ series controller with fuzzy logic. There is no need for relays, circuit breakers and power switches to be wired.
