PH 402 Environmental
What it is
The ESPEC PH 402 is an environmental chamber used as a horizontal-type industrial oven. The PH 402 has an interior volume of 35.3 cubic feet, or 1000 liters, and interior dimensions of 1000 by 1000 by 1000 millimeters.[1][2][3]
The PH 402 operates over a temperature range from 45°C to 200°C. The PH 402 uses 208 V power, three-phase, 60 Hz service, and 30 service amps.[1][2][3]
How it works
The PH 402 includes an ESPEC controller with a large LED display. The PH 402 also has two-step programmability with automatic start, stop, ramp, and repeat functions, plus a visual and audible alarm with diagnostic fault code and a specimen power supply control terminal that turns specimen power off if the chamber faults.[2]
The PH 402 includes a four-tier safety system for overheat conditions, an exhaust damper for ventilating the oven and fast cool-down, and two shelves included as standard.[2]
