This is a fully functional Thermotron SE-300-2-2 Temperature/Humidity Test Chamber (-70°C to +170°C, 10% to 95% R.H.) in excellent cosmetic and working conditions. The chamber has a working space of 10.2 cu. ft. with interior chamber dimensions of 24”W x 26”D x 28”H. The interior chamber has four sets of rails for shelf moving in and out. This chamber has been very well maintained and just fully tested and validated by our engineer. It controls the temperature and humidity very precisely, well within the manufacturer's specifications. The chamber has a temperature range of -70°C to +170°C and humidity range from 10% to 95% R.H. (in the dry bulb range from + 7°C to + 85°C) that have been tested and verified. It has a very clean stainless-steel interior chamber. The chamber comes with a transparent glass observing window and interior light. The chamber has a built-in IEEE 488 computer connector.
Different temperatures with different humidity levels have been tested, including the most used temperature humidity conditions: 85°C / 85% RH (Damp Heat), 65°C / 75% RH, 65°C / 95% RH, 40°C / 93% RH, and different temperatures of 170°C, 120°C, 85°C , 25°C, 4°C, -10°C, -20°C, -30°C, -40°CoC, -55°C, -70°C. The chamber is a complete ready-to-use system with everything needed for testing operation. Technical support will be provided to the buyer for the initial applications, if requested. The functionalities of the compressors, heating elements, water supply and drain system, and humidity and temperature control system have just been thoroughly checked and validated. The chamber uses 208 - 230 Volts single phase 60 H power.
Temperature and humidity conditions are controlled by a user-friendly two-channel 7800 Programmer/Controller that is a programmable microcomputer. The user can program the 7800 to automatically operate the chamber, or can manually operate the chamber using the 7800 front panel keyboard and display, or operate the 7800 from a host computer. Channel 1 senses the chamber temperature using a dry bulb thermocouple input. Its output controls the heating and cooling systems. Channel 2 senses the chamber humidity. Its output controls the humidity system’s steam generator and dehumidify coil.
The following electronic manuals for both the chamber and the 7800 programmer/controller will be provided with the chamber: 1) SE-Series Environmental Chamber Manual 2) 7800 Programmer-Controller Technical Manual 3) 7800 Programmer-Controller Operator Manual 4) 7800 Programmer-Controller Computer Interface Manual.
