This the most versatile low temperature indicator for biochemical oxygen demand determination. Caster wheel mounted cabinet is double walled with inner chamber Of anodized aluminum of stainless steel and outer casing of M.S. sheet duly painted. The gap of 75 m.m. between the outer and the inner wall is filled with special grade glass wool to prevent thermal losses. Triple walled back of the unit is fitted with two air circulation fans for maintaining temperature uniform ally through the chamber. Heating elements of nicrome wire are placed in the air path and are duly insulated from the body. The inner chamber is ribbed for placement of shelves at desired height. Full view inner glass door permits inspection of specimens, without disturbing the same, lock and key arrangement Is provided in the double walled outer door. Unit is fitted with door operated illumination lamp inside the chamber. The temperature range from 5 degree c to 50 degree c is controlled by two EGO/JUMO German double action hydraulic capillary thermostat. Refrigeration unit is formed by Hermetically sealed ISI marked SHRIRAM make compressor and the cooling coils are distributed all round the chamber and lie in the air circulation path. An l-shaped prismatic Thermometer is provided at the top on the front panel along with separate indicator lamps for mains, heating and incoming voltage. Supplied complete with 3 shelves, cord and plug to work on 220/230v A.C. supply.
