About this file
This document is a product specifications sheet for the Thermotron SM-1.0-8200, a compact environmental test chamber designed for temperature and humidity control applications.
The chamber features a workspace of 14" W x 8" D x 14" H with a total volume of 0.89 cubic feet and move-in dimensions of 18" W x 23" D x 30" H, weighing 250 lbs. Operating on 115V single-phase 60Hz power with a 20-amp service requirement, the unit requires 13.8 estimated full load amps and incorporates a 1/3 horsepower compressor. The chamber achieves a temperature range of -40°F to +266°F with humidity control from 20% RH to 95% RH, limited by a +59°F minimum dew point and +185°F maximum dry bulb. Temperature control tolerance is ±2°F with humidity control tolerance of ±2.5% RH above 68°F. Cooling performance reaches 14°F in 11 minutes and -4°F in 22 minutes from ambient (77°F), while heating reaches 150°F in 6 minutes and 230°F in 16 minutes. Water requirements are 0.1 to 0.2 gallons per hour of 5-micron filtered water supplied via manual tank feed only, with a self-contained 6-liter humidity reservoir.
Standard construction includes a heliarc-welded stainless steel chamber liner, left-hand hinged door, sheet metal exterior with removable service panels, and non-burning fiberglass insulation. The refrigeration system uses a hermetically sealed single-stage compressor with CFC-free refrigerant and air-cooled condenser. Electrical features include Nichrome heating elements with stainless steel frames, solid-state photo-isolated zero voltage switching control relays, circuit breaker protection, and a hi-heat limit for over-temperature protection. The humidity system incorporates sheath immersion heaters, electronic humidity sensor, and a refrigerated dehumidification coil for dew points above 59°F.
